The microflora is dominated by Quercus pollen. Pollen ornamentations indicate that Quercus pollen most likely originated from species of sections Quercus, Lobatae, Quercus/Lobatae and aff. section Protobalanus. Eotrigonobalanus, an extinct Fagaceae lineage, was present in the coastal plain. Relative abundances of several tree taxa (e.g., Carya) did not change significantly between the Oligocene warm phases, but contrast to late middle Miocene (comprising most of the Langhian and Serravallian) records from the same area. By assigning terrestrial palynomorphs to paleovegetation units, topographic movements of these units were identified. The mesophytic forest was the most widespread and zonal vegetation type in the hinterland through the analyzed interval. Periodic changes in the relative abundances of paleovegetation units suggest altitudinal vegetation movements responding to global climate change. Observed movement signals are generally weak, but increases in bisaccate pollen, representing spread of high- and mid-latitude forest, probably reflect the onset of cold intervals such as cooling phases at ~ 29.1, ~ 28.5, and 23.5 Ma. Spread of edaphically controlled forest formations during regression phases also indicates climate change. The onset of the Mi-1 event at ~ 23.03 Ma is probably reflected by a decrease in pollen-inferred paleotemperatures, although the event itself occurred during a sedimentation hiatus. Pollen-based paleoclimate reconstructions indicate long-term stability in temperature and precipitation within the humid warm temperate zone. © 2020 Elsevier B.V. 2020 English 00346667 10.1016/j.revpalbo.2020.104224 Review of Palaeobotany and Palynology 279 Elsevier B.V.

Donders article Cosgrove20191291 Trajectories of successive clinoform rollovers are widely applied to predict patterns of spatio-temporal sand distribution. However, the detailed internal architecture of individual clinothems is rarely documented. Understanding the textural complexities of complete topset-foreset-bottomset clinothem sequences is a key factor in understanding how and when sediment is transferred basinward. This study used high-resolution, core-based analyses of 267 samples from three research boreholes from quasi-coeval topset, foreset, and bottomset deposits of a single Miocene intrashelf clinothem recovered during Integrated Ocean Drilling Program (IODP) Expedition 313, offshore New Jersey, USA. Topset deposits were subdivided into three sedimentary packages based on grain character and facies analysis, consisting of upper and lower river-dominated topset process-regime packages separated by a middle wave- and storm-dominated process-regime package. Temporal variability in topset process regime exerts a quantifiable effect on grain character across the complete depositional profile, which was used here to correlate topset deposits with time-equivalent sedimentary packages in foreset and bottomset positions. River-dominated sedimentary packages have higher sand-to-mud ratios; however, the grain character of river-dominated sedimentary packages is texturally less mature than that of wave- and storm-dominated deposits. Differences in grain character between packages dominated by different process regimes increase basinward. The novel use of quantitative grain-character data allows intraclinothem time lines to be established at a higher resolution than is possible using chronostratigraphic techniques. Additionally, stratigraphic changes in grain character were used to refine the placement of the basal sequence boundary. These results challenge the idea that clinoform trajectories and stacking patterns are sufficient to describe spatio-temporal sand-body evolution across successive clinothems. © 2019 The Authors. 2019 English 1553040X 10.1130/GES02046.1 Geosphere 15 Geological Society of America 1291-1322 School of Earth and Environment, University of Leeds, Leeds, LS2 9JT, United Kingdom 4 Deposits; Offshore boreholes; Offshore oil well production; Rivers; Sedimentology; Storms; Stratigraphy, Higher resolution; Integrated ocean drilling programs; Internal architecture; Sand distribution; Sedimentary packages; Stratigraphic changes; Temporal variability; Textural complexity, Sand, chronostratigraphy; correlation; deposition; facies analysis; Miocene; Ocean Drilling Program; offshore application; resolution; sand; sedimentary structure, New Jersey; United States https://www.scopus.com/inward/record.uri?eid=2-s2.0-85070791459&doi=10.1130%2fGES02046.1&partnerID=40&md5=66f6b138649dd2fcae52dadc4d71ce4a cited By 3 G.I.E. Cosgrove D.M. Hodgson N.P. Mountney W.D. McCaffrey article Gulick2019157 Shorelines are ephemeral features, yet many science problems cross this ever-moving boundary and require sampling on both its dry and wet sides. The logistics of working on land and at sea are distinct, such that funding agencies in many countries divide their research programs at the shoreline. Similarly, scientific drilling is split between the International Ocean Discovery Program (IODP) in the ocean and the International Continental Scientific Drilling Program (ICDP) on land. Here, we discuss three examples of drilling projects that effectively coordinated activities between IODP and ICDP and highlight the need for increasing cooperation and coordination across the shoreline. We end by casting an eye toward the future of scientific drilling, where truly amphibious projects are now possible. © 2019 The Oceanography Society, Inc. 2019 English 10428275 10.5670/oceanog.2019.139 Oceanography 32 Oceanography Society 157-159 Institute for Geophysics, Department of Geological Sciences, Jackson School of Geosciences, The University of Texas at Austin, Austin, TX, United States; Department of Earth and Planetary Sciences, Rutgers University, Piscataway, NJ, United States; Lamont-Doherty Earth Observatory, Columbia University, Palisades, NY, United States; Department of Earth Science and Engineering, Imperial College London, London, United Kingdom; Géosciences Rennes, Université de Rennes 1, Rennes, France; Department of Geology, Faculty of Science, Niigata University, Research and Development Center for Ocean Drilling Science, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan 1 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85066038967&doi=10.5670%2foceanog.2019.139&partnerID=40&md5=161ad26af297d7363c834c5e3041dcca cited By 1 S.P.S. Gulick K. Miller P. Kelemen J. Morgan J.-N. Proust E. Takazawa article Riedel201917 Numerical modelling of fluid flow and transport processes relies on a well-constrained geological model, which is usually provided by seismic reflection surveys. In the New Jersey shelf area a large number of 2D seismic profiles provide an extensive database for constructing a reliable geological model. However, for the purpose of modelling groundwater flow, the seismic data need to be depth-converted which is usually accomplished using complementary data from borehole logs. Due to the limited availability of such data in the New Jersey shelf, we propose a two-stage processing strategy with particular emphasis on reflection tomography and pre-stack depth imaging. We apply this workflow to a seismic section crossing the entire New Jersey shelf. Due to the tomography-based velocity modelling, the processing flow does not depend on the availability of borehole logging data. Nonetheless, we validate our results by comparing the migrated depths of selected geological horizons to borehole core data from the IODP expedition 313 drill sites, located at three positions along our seismic line. The comparison yields that in the top 450 m of the migrated section, most of the selected reflectors were positioned with an accuracy close to the seismic resolution limit (≈ 4 m) for that data. For deeper layers the accuracy still remains within one seismic wavelength for the majority of the tested horizons. These results demonstrate that the processed seismic data provide a reliable basis for constructing a hydrogeological model. Furthermore, the proposed workflow can be applied to other seismic profiles in the New Jersey shelf, which will lead to an even better constrained model. © 2018, Springer Science+Business Media B.V., part of Springer Nature. 2019 English 00253235 10.1007/s11001-018-9360-9 Marine Geophysical Research 40 Springer Netherlands 17-32 Department of Geosciences and Geography, University of Helsinki, P.O.

Riedel S. Reiche K. Aßhoff S. Buske article Proust20181564 Understanding the history, causes, and impact of sea-level changes is a challenge for our societies that face accelerated global sea-level rise. In this context, improvement of our knowledge of sea-level changes and shoreline migration at geological time scales is critical. The preserved, laterally correlative sedimentary record of continental erosion on passive margins has been used to reconstruct past sea level. However, the detailed nature of a basic clinothem progradational pattern observed on many of these margins is still poorly known. This paper describes the sedimentary facies and interprets the depositional environments and the architecture of the clinothems of the New Jersey shelf (offshore northeastern USA) to depict the origin and controls of the distribution of the sediment on the margin. We analyze 612 cores totaling 1311 m in length collected at three sites 60 km offshore Atlantic City, New Jersey, during International Ocean Discovery Program-International Continental Scientific Drilling Program (IODP-ICDP) Expedition 313. The three sites sampled the lower to middle Miocene passive margin sediments of the New Jersey shelf clinothems. We also collected wireline logs at the three sites and tied the sedimentary architecture to the geometry observed on seismic profiles. The observed sediment distribution in the clinoform complex differs from that of current models based on seismic data, which predict a progressive increase in mud and decrease in sand contents in a seaward direction. In contrast, we observe that the clinoforms are largely composed of muds, with sands and coarser material concentrated at the rollover, the bottomset, and the toe of the slope. The shelf clinothem topsets are storm-influenced mud whereas the foreset slope is composed of a mud wedge largely dominated by density current deposits (e.g., low-density turbidites and debrites). The architecture of the clinothem complex includes a composite stack of ~30-m-thick clinothem units each made up of four systems tracts (Transgressive, Highstand, Forced- Regressive, and Lowstand Systems Tract) building individual transgressiveregressive sequences. The presence of mud-rich facies deposited during highstands on the topset of the clinoform, 40-60 km offshore from the sand-prone shoreface deposit (observed in the New Jersey onshore delta plain), and the lack of subaerial erosion (and continental depositional environments) point to a depositional model involving a subaerial delta (onshore) feeding a distant subaqueous delta. During forced regressions, shelf-edge deltas periodically overstep the stacks of flood-influenced, offshore-marine mud wedges of the New Jersey subaqueous delta, bringing sand to the rollover and building up the large-scale shelf-prism clinothems. The clinothem complex develops on a gently dipping platform with a ramp-like morphology (apparent dip of 0.75°-0.5°) below mean storm wave base, in 30-50 m of water depth, 40-60 km seaward of the coastal area. Its shape depends on the balance between accommodation and sedimentation rates. Subaqueous deltas show higher accumulation rates than their subaerial counterparts and prograde three times further and faster than their contemporaneous shoreline. The increase in the intensity of waves (height and recurrence intervals) favors the separation between subaqueous and subaerial deltas, and as a consequence, the formation of a flat topset geometry, a decrease in flood events and fluvial discharge, an overall progressive decrease in sediment grain size (from sequence m5.45, ca. 17.8-17.7 Ma, onwards), as well as an increase in sedimentation rates on the foresets of the clinoforms. All of these are recognized as preliminary signals that might characterize the entry into the Neogene icehouse world. © 2018 The Authors. 2018 English 1553040X 10.1130/GES01545.1 Geosphere 14 Geological Society of America 1564-1591 Geosciences, CNRS, University of Rennes, Rennes, 35042, France; Department of Earth Science, College of Science, Ibaraki University, Bunkyo Mito, 310-8512, Japan; Camborne School of Mines, University of Exeter, Penryn Campus, Penryn, Cornwall, TR10 9FE, United Kingdom; School of Earth and Environment, University of Leeds, Leeds, LS2 9JT, United Kingdom; Géosciences, CNRS, University of Montpellier, Montpellier, 34090, France; Géosciences Océan, CNRS, Institut Universitaire Européen de La Mer, Plouzané, 29280, France; New Jersey Geological Survey, Trenton, NJ 08638, United States 4 Deposits; Erosion; Floods; Sand; Sea level; Sedimentology; Seismic waves; Seismology; Storms; Tectonics, Continental scientific drillings; Depositional environment; Depositional models; Facies architecture; Global sea level rise; Recurrence intervals; Sediment distribution; Sedimentary architecture, Sediments, continental margin; depositional environment; facies analysis; Miocene; passive margin; progradation; reconstruction; sea level change; spatial distribution, Atlantic Ocean; New Jersey Shelf https://www.scopus.com/inward/record.uri?eid=2-s2.0-85051137615&doi=10.1130%2fGES01545.1&partnerID=40&md5=e363d248d76d5ded08d4967aa327a334 cited By 8 J.-N.

During IODP Expedition 313, siliciclastic deposits of late Eocene to late Pleistocene age were drilled down to 631, 669 and 755 m below seafloor at sites 27A, 28A and 29A respectively in very shallow waters (33.5 to 36 m depth). Pore water salinities display multilayered brackish-salty-brine units 10 to 170 m thick, where low-salinity water is preferentially stored in fine-grained sediments. The sharp boundaries of these buried aquifers are often marked by cemented layers a few centimetres thick. The mineralogy and scanning electron microscope observations of these layers show two phases of cementation by authigenic minerals: (1) the early carbonate cement is frequently associated with pyrite, and (2) the late silicate cement infills the residual porosity. The isotopic compositions of the carbonate cements vary widely: −2.4 < δ18O ‰ VPDB < +2.8; −15.1 < δ13C ‰ VPDB < +15.6. The δ18O values indicate that the carbonate cements precipitated with pore waters comprising variable mixtures of seawater and 18O-depleted fresh water originating from submarine groundwater discharge. The δ13C values of the carbonate cements are related to organic matter diagenesis, providing 13C-depleted dissolved inorganic carbon during bacterial sulphate reduction and anaerobic oxidation of methane, and 13C-rich dissolved inorganic carbon during methanogenesis. The diagenetic cementation processes included chemical weathering of reactive silicate minerals by the CO2-rich pore waters issued from organic matter diagenesis that released bicarbonate, cations and dissolved silica, which were further precipitated as carbonate and silicate cements. The estimated range of temperature (18±4 °C) during carbonate precipitation is consistent with carbonate cementation at moderate burial depths; however, silicate cementation occurred later during diagenesis at deeper burial depths. © 2017, Springer-Verlag Berlin Heidelberg. 2017 English 02760460 10.1007/s00367-017-0506-6 Geo-Marine Letters 37 Springer Verlag 537-547 UPMC-Sorbonne Universités, LOCEAN, 4 place Jussieu, Paris Cedex 05, 75252, France; MNHN-Sorbonne Universités, CR2P, 57 rue Cuvier, Paris, 75005, France; UPMC-Sorbonne Universités, ISTEP, 4 place Jussieu, Paris Cedex 05, 75252, France; Geosciences Montpellier, Université Montpellier, Montpellier Cedex 5, 34095, France 6 Aquifers; Biogeochemistry; Biological materials; Carbon; Carbon dioxide; Carbonation; Cementing (shafts); Discharge (fluid mechanics); Dissolution; Groundwater; Groundwater resources; Hydrogeology; Minerals; Organic compounds; Organic minerals; Scanning electron microscopy; Sedimentology; Silicate minerals; Silicates; Submarines; Water; Weathering, Anaerobic oxidation of methanes; Bacterial sulphate reductions; Carbonate precipitation; Dissolved inorganic carbon; Fine-grained sediment; Pore water salinities; Siliciclastic sediments; Submarine groundwater discharge, Cements, carbonate sediment; cementation; chemical weathering; continental shelf; discharge; groundwater; Ocean Drilling Program; organic matter; silicate mineral; siliciclastic deposit; underwater environment, Atlantic Ocean; New Jersey Shelf, Bacteria (microorganisms) https://www.scopus.com/inward/record.uri?eid=2-s2.0-85017156984&doi=10.1007%2fs00367-017-0506-6&partnerID=40&md5=bbd8001cb936f14dba670691b81563d9 cited By 3 C. Pierre M.-M. Blanc-Valleron O. Boudouma J. Lofi article Hodgson201795 Drilling of intrashelf Miocene clinothems onshore and offshore New Jersey has provided better understanding of their topset and foreset deposits, but the sedimentology and stratigraphy of their bottomset deposits have not been documented in detail. Three coreholes (Sites M27-M29), collected during Integrated Ocean Drilling Program (IODP) Expedition 313, intersect multiple bottomset deposits, and their analysis helps to refine sequence stratigraphic interpretations and process response models for intrashelf clinothems. At Site M29, the most downdip location, chronostratigraphically well-constrained bottomset deposits follow a repeated stratigraphic motif. Coarse-grained glauconitic quartz sand packages abruptly overlie deeply burrowed surfaces. Typically, these packages coarsen then fine upwards and pass upward into bioturbated siltstones. These coarse sand beds are amalgamated and poorly sorted and contain thin-walled shells, benthic foraminifera, and extrabasinal clasts, consistent with an interpretation of debrites. The sedimentology and mounded seismic character of these packages support interpretation as debrite-dominated lobe complexes. Farther updip, at Site M28, the same chronostratigraphic units are amalgamated, with the absence of bioturbated silts pointing to more erosion in proximal locations. Graded sandstones and dune-scale cross-bedding in the younger sequences in Site M28 indicate deposition from turbidity currents and channelization. The sharp base of each package is interpreted as a sequence boundary, with a period of erosion and sediment bypass evidenced by the burrowed surface, and the coarse-grained debritic and turbiditic deposits representing the lowstand systems tract. The overlying fine-grained deposits are interpreted as the combined transgressive and highstand systems tract deposits and contain the deepwater equivalent of the maximum flooding surface. The variety in thickness and grain-size trends in the coarse-grained bottomset packages point to an autogenic control, through compensational stacking of lobes and lobe complexes. However, the large-scale stratigraphic organization of the bottomset deposits and the coarse-grained immature extrabasinal and reworked glauconitic detritus point to external controls, likely a combination of relative sea-level fall and waxing- and-waning cycles of sediment supply. This study demonstrates that large amounts of sediment gravity-flow deposits can be generated in relatively shallow (~100-200 m deep) and low-gradient (~1°-4°) clinothems that prograded across a deep continental shelf. This physiography likely led to the dominance of debris flow deposits due to the short transport distance limiting transformation to low-concentration turbidity currents. © 2017 The Authors. 2017 English 1553040X 10.1130/GES01530.1 Geosphere 14 Geological Society of America 95-114 Stratigraphy Group, School of Earth and Environment, University of Leeds, Leeds, LS2 9JT, United Kingdom; Department of Earth and Planetary Sciences, Rutgers University, Piscataway, NJ 08854, United States; Camborne School of Mines, University of Exeter, Penryn Campus, Penryn, Cornwall, TR10 9FE, United Kingdom; Department of Geosciences, University of Oslo, Oslo, 0371, Norway; Géosciences Rennes, CNRS, Université de Rennes, Campus de Beaulieu, Rennes, 35042, France 1 Erosion; Ocean currents; Offshore drilling; Sea level; Sediment transport; Sedimentology; Sediments; Stratigraphy; Thin walled structures; Turbidity, Benthic foraminifera; Compensational stacking; Highstand systems tract; Integrated ocean drilling programs; Maximum flooding surfaces; Sediment gravity flow; Sequence-stratigraphic interpretation; Stratigraphic organizations, Deposits, chronostratigraphy; debris flow; Miocene; quartz; sediment transport; sedimentology, New Jersey; United States, Foraminifera https://www.scopus.com/inward/record.uri?eid=2-s2.0-85041464062&doi=10.1130%2fGES01530.1&partnerID=40&md5=ab562085ccc23354f8fa105321a5a9e2 cited By 26 D.M.

Proust article Kominz20161437 Onshore drilling by Ocean Drilling Program (ODP) Legs 150X and 174AX and offshore drilling by Integrated Ocean Drilling Program (IODP) Expedition 313 provides continuous cores and logs of seismically imaged Lower to Middle Miocene sequences. We input ages and paleodepths of these sequences into one-dimensional backstripping equations, progressively accounting for the effects of compaction, Airy loading, and thermal subsidence. The resulting difference between observed subsidence and theoretical thermal subsidence provide relative sea-level curves that reflect both global average sea level and non-thermal subsidence. In contrast with expectations, backstripping suggests that the relative sea-level maxima in proximal onshore sites were lower than correlative maxima on the shelf. This requires that the onshore New Jersey coastal plain has subsided relative to the shelf, which is consistent with models of relative epeirogeny due to subduction of the Farallon plate. These models predict subsidence of the coastal plain relative to the shelf. Although onshore and offshore sea-level estimates are offset by epeirogeny, the amplitude of million-year-scale Early to Middle Miocene sea-level changes seen at the New Jersey margin is generally 5-20 m and occasionally as great as 50 m. These events are interpreted to represent eustatic variations, because they occur on a shorter time frame than epeirogenic influences. Correction for epeirogenic effects largely reconciles differences between onshore and offshore relative sea-level estimates and suggests that backstripping provides a testable eustatic model for the Early to Middle Miocene. 2016 English 1553040X 10.1130/GES01241.1 Geosphere 12 Geological Society of America 1437-1456 Department of Geosciences, Western Michigan University, 1186 Rood Hall, 1903 West Michigan Avenue, Kalamazoo, MI 49008, United States; Department of Earth and Planetary Sciences, Institute of Earth, Oceans, and Atmospheric Sciences, Rutgers, The State University of New Jersey, 610 Taylor Road, Piscataway, NJ 08854-8066, United States; Department of Earth and Planetary Sciences, Rutgers, The State University of New Jersey, 610 Taylor Road, Piscataway, NJ 08854-8066, United States; Department of Earth and Environmental Sciences, Rensselaer Polytechnic Institute, 110 8th Street, Troy, NY 12180, United States 5 Offshore drilling; Submarine geology; Subsidence; Tectonics, Continental shelves; Integrated ocean drilling programs; Middle Miocene; Ocean drilling programs; Offshore sea level; Onshore drilling; Relative sea level; Sealevel change, Sea level, coastal plain; continental shelf; eustacy; Miocene; Ocean Drilling Program; paleoceanography, New Jersey; United States https://www.scopus.com/inward/record.uri?eid=2-s2.0-84993967985&doi=10.1130%2fGES01241.1&partnerID=40&md5=429a4c7ca9a661f7d42fba0c2c016699 cited By 26 M.A. Kominz K.G.

Mountain article Kotthoff20141523 We investigated the palynology of sediment cores from Site M0027 of IODP (Integrated Ocean Drilling Program) Expedition 313 on the New Jersey shallow shelf to examine vegetation and climate dynamics on the east coast of North America between 33 and 13 million years ago and to assess the impact of over-regional climate events on the region. Palynological results are complemented with pollen-based quantitative climate reconstructions. Our results indicate that the hinterland vegetation of the New Jersey shelf was characterized by oak-hickory forests in the lowlands and conifer-dominated vegetation in the highlands from the early Oligocene to the middle Miocene. The Oligocene witnessed several expansions of conifer forest, probably related to cooling events. The pollen-based climate data imply an increase in annual temperatures from ∼11.5 °C to more than 16 °C during the Oligocene. The Mi-1 cooling event at the onset of the Miocene is reflected by an expansion of conifers and mean annual temperature decrease of ∼4 °C, from ∼16 °C to ∼12 °C around 23 million years before present. Relatively low annual temperatures are also recorded for several samples during an interval around ∼20 million years before present, which may reflect the Mi-1a and the Mi-1aa cooling events. Generally, the Miocene ecosystem and climate conditions were very similar to those of the Oligocene. Miocene grasslands, as known from other areas in the USA during that time period, are not evident for the hinterland of the New Jersey shelf, possibly reflecting moisture from the proto-Gulf Stream. The palaeovegetation data reveal stable conditions during the mid-Miocene climatic optimum at ∼15 million years before present, with only a minor increase in deciduous-evergreen mixed forest taxa and a decrease in swamp forest taxa. Pollen-based annual temperature reconstructions show average annual temperatures of ∼14 °C during the mid-Miocene climatic optimum, ∼2 °C higher than today, but ∼1.5 °C lower than preceding and following phases of the Miocene. We conclude that vegetation and regional climate in the hinterland of the New Jersey shelf did not react as sensitively to Oligocene and Miocene climate changes as other regions in North America or Europe due to the moderating effects of the North Atlantic. An additional explanation for the relatively low regional temperatures reconstructed for the mid-Miocene climatic optimum could be an uplift of the Appalachian Mountains during the Miocene, which would also have influenced the catchment area of our pollen record. © Author(s) 2014. 2014 English 18149324 10.5194/cp-10-1523-2014 Climate of the Past 10 1523-1539 Institut für Geologie, Centrum für Erdsystemforschung und Nachhaltigkeit, Universität Hamburg, Bundesstraße 55, 20146 Hamburg, Germany; Department of Biology, Brandon University, 270 18th Street, Brandon, MN, R7A 6A9, Canada; Department of Earth Sciences, Brock University, 500 Glenridge Avenue, St. Catharines, ON, L2S 3A1, Canada; Camborne School of Mines, College of Engineering, Mathematics and Physical Sciences, University of Exeter, Treliever Road, Penryn, Cornwall TR10 9FE, United Kingdom 4 climate variation; Eocene; Miocene; paleoclimate; palynology; reconstruction; regional climate; sediment core, Atlantic Coastal Plain; New Jersey; United States https://www.scopus.com/inward/record.uri?eid=2-s2.0-84936933799&doi=10.5194%2fcp-10-1523-2014&partnerID=40&md5=75a88e0e41af19d6009695be3182d56e cited By 29 U.

Hesselbo article Fang20131303 The stratigraphic utility of carbon-isotope values from terrestrial organic matter is explored for Miocene siliciclastic sediments of the shallow shelf, New Jersey margin, USA (Integrated Ocean Drilling Program [IODP] Expedition 313). These shallow marine strata, rich in terrestrial organic matter, provide a record of deposition equivalent to the Monterey event, a prolonged interval of time characterized by relatively positive carbon-isotope values recorded from foraminiferal carbonate in numerous oceanic settings. Coherent stratigraphic trends and short-term isotopic excursions are observed consistently in palynological preparation residues, concentrated woody phytoclasts, and individually picked woody phytoclasts obtained from the New Jersey sediments. A bulk organic matter curve shows somewhat different stratigraphic trends but, when corrected for mixing of marine-terrestrial components on the basis of measured C/N ratios, a high degree of conformity with the woody phytoclast record is observed. However, assuming that the correlations based on strontium-isotope values and biostratigraphy are correct, the carbon-isotope record from the New Jersey margin contrasts with that previously documented from oceanic settings (i.e., lack of positive excursion of carbonisotope values in terrestrial organic matter through the Langhian Stage). Factors that may potentially bias local terrestrial carbonisotope records include reworking from older deposits, degradation and diagenesis, as well as environmental factors affecting vegetation in the sediment source areas. These possible factors are assessed on the basis of pyrolysis data, scanning electron microscope observations, and comparison to palynological indices of environmental change. Some evidence is found for localized degradation and/or reworking of older woody phytoclasts, but where such processes have occurred they do not readily explain the observed carbon-isotope values. It is concluded that the overall carbon-isotope signature for the exchangeable carbon reservoir is distorted, to the extent that the Monterey event excursion is not easily identifiable. The most likely explanation is that phytoclast reworking has indeed occurred in clinoform toe-ofslope facies, but the reason for the resulting relatively heavy carbon-isotope values in the Burdigalian remains obscure. © 2013 Geological Society of America. 2013 English 1553040X 10.1130/GES00851.1 Geosphere 9 1303-1318 Department of Earth Sciences, University of Oxford, South Parks Road, Oxford OX1 3AN, United Kingdom; Camborne School of Mines, College of Engineering, Mathematics and Physical Sciences, University of Exeter, Tremough Campus, Penryn, Cornwall TR10 9EZ, United Kingdom; Nordic Centre for Earth Evolution (NordCEE), Department of Geosciences and Natural Resource Management, University of Copenhagen, Øster Voldgade 10, DK-1350, Copenhagen K, Denmark; Institut für Geologie, Universität Hamburg, Bundesstrasse 55, 20146 Hamburg, Germany; Department of Earth Sciences, Brock University, 500 Glenridge Avenue, St. Catharines, Ontario L2S 3A1, Canada; School of Earth and Space Science, Peking University, 5 Yiheyuan Road, Beijing 100871, China; Research Laboratory for Archaeology and History of Art (RLAHA), University of Oxford, South Parks Road, Oxford OX1 3QY, United Kingdom 5 carbon isotope; deposition; environmental factor; Miocene; mixing; organic matter; palynology; pyrolysis; shelf sediment; siliciclastic deposit; stratigraphy; strontium isotope, New Jersey; United States https://www.scopus.com/inward/record.uri?eid=2-s2.0-84885167117&doi=10.1130%2fGES00851.1&partnerID=40&md5=d431e4f0151f009b84cf03f1da1e5ff5 cited By 8 L.

Ditchfield article Breuker2013578 The investigated deeply buried marine sediments of the shallow shelf off New Jersey, USA, are characterized by low organic carbon content and total cell counts of < 107 cells per mL sediment. The qPCR data for Bacteria and Archaea were in the same orders of magnitude as the total cell counts. Archaea and Bacteria occurred in similar 16S rRNA gene copy numbers in the upper part of the sediments, but Bacteria dominated in the lowermost part of the analyzed sediment cores down to a maximum analyzed depth of c. 50 meters below seafloor (mbsf). The bacterial candidate division JS1 and the classes Anaerolineae and Caldinilineae of the Chloroflexi were almost as highly abundant as the total Bacteria. Similarly high dsrA gene copy numbers were found for sulfate reducers. The abundance of the Fe(III) and Mn(IV) reducers comprising Geobacteraceae in the upper c. 15 mbsf correlated with concentrations of manganese and iron in the pore water. The isolated 16S rRNA gene sequences of Archaea in clone libraries could be allocated to the phyla Thaumarchaeota, Euryarchaeota, and Crenarchaeota with 1%, 14%, and 85%, respectively. The typical deep subsurface sediment-associated groups MBG-B, MBG-D, MCG, and SAGMEG were represented in the sediment community. MCG was the dominant group with a high diversity of the isolated 16S rRNA gene sequences. © 2013 Federation of European Microbiological Societies. 2013 English 01686496 10.1111/1574-6941.12146 FEMS Microbiology Ecology 85 578-592 Bundesanstalt für Geowissenschaften und Rohstoffe, Hannover, Germany 3 RNA 16S, abundance; biosphere; data set; gene; manganese; marine sediment; microbial community; organic carbon; polymerase chain reaction; porewater; seafloor; shallow soil; sulfate, archaeon; article; bacterium; biodiversity; Chloroflexi; classification; Crenarchaeota; deep biosphere; Deltaproteobacteria; Euryarchaeota; genetics; IODP; isolation and purification; microbiology; Miscellaneous Crenarchaeotal Group; phylogeny; sea; sediment; sediments; travel; United States, Crenarchaeota; deep biosphere; Euryarchaeota; IODP; Miscellaneous Crenarchaeotal Group; sediments, Archaea; Bacteria; Biodiversity; Chloroflexi; Crenarchaeota; Deltaproteobacteria; Euryarchaeota; Expeditions; Geologic Sediments; New Jersey; Oceans and Seas; Phylogeny; RNA, Ribosomal, 16S, New Jersey; United States, Anaerolineae; Archaea; Bacteria (microorganisms); Chloroflexi; Chloroflexi (class); Crenarchaeota; Euryarchaeota; Geobacteraceae; Lake Victoria marburgvirus https://www.scopus.com/inward/record.uri?eid=2-s2.0-84881557283&doi=10.1111%2f1574-6941.12146&partnerID=40&md5=d0814b627f919b3645a9f3d5958adcf0 cited By 34 A. Breuker S. Stadler A. Schippers article Katz20131488 Integrated Ocean Drilling Program (IODP) Expedition 313 drilled three holes (Sites M27, M28, and M29; 34-36 m present water depth) across a series of prograding clinothems from the inner continental shelf of the New Jersey (USA) margin, a region that is sensitive to sea-level change. We examined 702 late Eocene to Miocene samples for benthic foraminiferal assemblages and planktonic foraminiferal abundances. We integrate our results with lithofacies to reconstruct paleobathymetry. Biofacies at all three sites indicate a long-term shallowing-upward trend as clinothems built seaward and sediment fi lled accommodation space. Patterns in biofacies and lithofacies indicate shallowing-and deepening-upward successions within individual sequences, providing the basis to recognize systems tracts, and therefore sequence stratigraphic relationships in early to early-middle Miocene sequences (ca. 23-13 Ma). The clinothem bottomsets and the lower portions of the foresets, which contain the thickest parts of clinothems, yield the deepest water biofacies. Shallower bio facies characterize the sequences in the upper portions of the clinothem foresets and on the topsets. Topsets are characterized by transgressive (TST) and highstand systems tracts (HST). Foresets contain lowstand systems tracts (LST), TSTs, and HSTs. Flooding surfaces mark parasequence boundaries within LSTs, TSTs, and HSTs. Superimposed on the long-term trends, short-term variations in paleowater depth are likely linked to global sea-level changes indicated by global oxygen isotopic variations. 2013 English 1553040X 10.1130/GES00872.1 Geosphere 9 1488-1513 Department of Earth and Environmental Sciences, Rensselaer Polytechnic Institute, 110 8th Street, Troy New York 12180, United States; Department of Earth and Planetary Sciences, Rutgers University, Piscataway, New Jersey 08854, United States; New Jersey Geological Survey, PO Box 427, Trenton New Jersey 07640, United States; Department of Earth, Atmospheric and Planetary Sciences, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139-4307, United States 6 Accommodation space; Benthic foraminifera; Foraminiferal assemblages; Highstand systems tract; Individual sequences; Integrated ocean drilling programs; Sequence-stratigraphic interpretation; Short-term variations, Sea level; Stratigraphy; Tectonics, Coastal zones, benthic foraminifera; continental shelf; depositional sequence; Eocene; Miocene; Ocean Drilling Program; parasequence; sequence boundary; sequence stratigraphy; systems tract; transgression, Atlantic Ocean; New Jersey Shelf, Foraminifera https://www.scopus.com/inward/record.uri?eid=2-s2.0-84889675272&doi=10.1130%2fGES00872.1&partnerID=40&md5=bef354d5234c70286656595ece33203f cited By 23 M.E.

Williams article Miller201374 We used cores and logs from Integrated Ocean Drilling Program (IODP) Expedition 313 to generate biostratigraphic, lithofacies, biofacies, and geochemical data that constrain the ages and paleoenvironments of Pleistocene sequences. We integrate sequence stratigraphy on cores with new seismic stratigraphic data to interpret the Pleistocene history of the Hudson shelf valley and paleoenvironmental and sea-level changes on the inner to middle continental shelf. Improved age control compared to previous studies is provided by integrated calcareous nannofossil biostratigraphy, Sr isotopic stratigraphy, and amino acid racemization. We recognize four upper Pleistocene-Holocene sequences: sequence uP1 is correlated with Marine Isotope Chrons (MIC; "chron" is the correct stratigraphic term for a time unit, not "stage") 7 or 5e, sequence uP2 with MIC 5c, sequence uP3 with MIC 5a, and sequence uP4 with the latest Pleistocene to Holocene (MIC 1-2). However, within our age resolution it is possible that sequences uP2 and uP3 correlate with MIC 4-3c and 3a, respectively, as suggested by previous studies. Lower Pleistocene sequences lP1 and lP2 likely correlate with peak interglacials (e.g., MIC 31 and MIC 45 or 47, respectively). Thus, we suggest that preservation of sequences occurs only during peak eustatic events (e.g., MIC 45 or 47, MIC 31, and MIC 5), unless they are preserved in eroded valleys. The architecture of the Pleistocene deposits at Sites M27 and M29 is one of thin remnants of highstand and transgressive systems tracts, with lowstand deposits only preserved in the thalwegs of incised valleys. Incised valleys at the bases of sequences uP3 (IODP Site M27) and uP2 (IODP Site M29) document more southward courses of the paleo-Hudson valley, compared to the more southeastward course of the MIC 1-2 paleo-Hudson valley. The patchy distribution of Pleistocene sequences beneath the New Jersey inner-middle continental shelf is due to low accommodation during an interval of large eustatic changes; this predicts that sequences in such settings will be discontinuous, patchy, and difficult to correlate, consistent with previous studies in Virginia and North Carolina. © 2013 Geological Society of America. 2013 English 1553040X 10.1130/GES00795.1 Geosphere 9 74-95 Department of Earth and Planetary Sciences, Rutgers University, Piscataway, NJ 08854, United States; GNS Science, Department of Paleontology, PO Box 30368, Lower Hutt 5040, New Zealand; Department of Geology, University of Delaware, Penny Hall, Newark, DE 19716, United States 1 biofacies; biostratigraphy; continental shelf; eustacy; incised valley; integrated approach; lithofacies; marine isotope stage; nanofossil; Ocean Drilling Program; paleoceanography; paleoenvironment; Pleistocene; Pleistocene-Holocene boundary; sea level change; seismic stratigraphy; sequence stratigraphy; thalweg; transgression, New Jersey; United States https://www.scopus.com/inward/record.uri?eid=2-s2.0-84873511052&doi=10.1130%2fGES00795.1&partnerID=40&md5=b9f8e75d882e8026d3ae77b9f82ca41c cited By 19 K.G.

Lombardi M.D. Feigenson article McCarthy20131457 Integrated Ocean Drilling Program Expedition 313 recovered Miocene sequences at Holes M0027A and M0029A on the New Jersey shallow shelf that contain a characteristic acid-resistant organic component. The palynofacies within each sequence refl ects variations in terrigenous versus authigenic fl ux through the Miocene that are associated with sea-level change. Very high ratios of terrigenous versus marine palynomorphs and of oxidation-resistant versus susceptible dinocysts are associated with seismic sequence boundaries, consistent with their interpretation as sequence-bounding unconformities generated at times of low sea level. Comparison of palynological distance from shoreline estimates with paleodepth estimates derived from foraminiferal data allows relative sea level to be reconstructed at both sites. Ages assigned using dinocyst biostratigraphy are consistent with other chronostratigraphic indicators allowing sequence boundaries to be correlated with Miocene oxygen isotope (Mi) events. Paleoclimatic evidence from the pollen record supports the global climate changes seen in the oxygen isotope data. Although chronological control is relatively crude, Milankovitch-scale periodicity is suggested for parasequences visible in thick sequences deposited in relatively deep water where substantial accommodation existed, such as during the early Langhian at Site 29 (Middle Miocene Climatic Optimum). Palyno logical analysis thus supports the long-held hypothesis that glacioeustasy is a dominant process controlling the architecture of continental margins. 2013 English 1553040X 10.1130/GES00853.1 Geosphere 9 1457-1487 Department of Earth Sciences, Brock University, Catharines, ONT L2S 3A1, Canada; Department of Earth and Environmental Sciences, Rensselaer Polytechnic Institute, Troy, NY 12180, United States; Institut für Geologie, Universität Hamburg, Bundesstrasse 55, 20146 Hamburg, Germany; Department of Earth and Planetary Sciences, Rutgers University, Piscataway, NJ 08854, United States; Camborne School of Mines, College of Engineering, Mathematics and Physical Sciences, University of Exeter, Penryn Campus, Penryn, Cornwall TR10 9EZ, United Kingdom; Nordic Centre for Earth Evolution (NordCEE), Department of Geosciences and Natural Resource Management, Øster Voldgade 10, DK-1350, Copenhagen K, Denmark 6 Continental margin; Global climate changes; Integrated ocean drilling programs; Organic components; Oxidation resistant; Relative sea level; Sea-level control; Sequence-bounding unconformities, Isotopes; Oxygen; Submarine geology, Sea level, biostratigraphy; chronostratigraphy; continental shelf; glacioeustacy; Miocene; Ocean Drilling Program; palynology; sea level change; sequence boundary; sequence stratigraphy, Atlantic Ocean; New Jersey Margin; New Jersey Shelf https://www.scopus.com/inward/record.uri?eid=2-s2.0-84889679284&doi=10.1130%2fGES00853.1&partnerID=40&md5=5ddec971bc45590c243fbaf5968b7c8c cited By 27 F.M.

Mountain article Inwood20131025 In this study, a novel application of a statistical approach is utilized for analysis of downhole logging data from Miocene-aged siliciclastic shelf sediments on the New Jersey Margin (eastern USA). A multivariate iterative nonhierarchical cluster analysis (INCA) of spectral gamma-ray logs from Integrated Ocean Drilling Program (IODP) Expedition 313 enables lithology within this siliciclastic succession to be inferred and, through comparison with the 1311 m of recovered core, a continuous assessment of depositional sequences is constructed. Signifi cant changes in INCA clusters corroborate most key stratigraphic surfaces interpreted from the core, and this result has particular value for surface recognition in intervals of poor core recovery. This analysis contributes to the evaluation of sequence stratigraphic models of large-scale clinoform complexes that predict depositional environments, sediment composition, and stratal geometries in response to sea-level changes. The novel approach of combining statistical analysis with detailed lithostratigraphic and seismic refl ection data sets will be of interest to any scientists working with downhole logs, especially spectral gamma-ray data, and also provides a reference for the strengths and weaknesses of multi component analysis applied to continental margin lithofacies. The method presented here is appropriate for evaluating successions elsewhere and also has value for hydrocarbon exploration where sequence stratigraphy is a fundamental tool. © 2013 Geological Society of America. 2013 English 1553040X 10.1130/GES00913.1 Geosphere 9 1025-1043 Department of Geology, University of Leicester, University Road, Leicester LE17RH, United Kingdom; Geosciences Montpellier, Unité Mixte de Recherche 5243, Université Montpellier 2, Bâtiment 22, 34095 Montpellier cedex, France; Institut des Sciences de la Terre, Université Joseph Fourier, BP 53, 38041 Grenoble CEDEX 9, France; Department of Geography and Geology, University of Copenhagen, OesterVoldgade 10, DK-1350 Copenhagen K, Denmark; Department of Earth and Planetary Sciences, Rutgers University, 610 Taylor Road, Piscataway, NJ 08854, United States; Unité Mixte de Recherche 6118 Centre National de la Recherche Scientifique Géosciences, Université de Rennes 1, 35042 Rennes cedex, France; Ocean Research Institute, University of Tokyo, Ocean Floor Geoscience, 1-15-1 Minamidai, Nakanoku, Tokyo, Japan; Thule Institute, University of Oulu, PO Box 7300, Oulu, FI-90014, Finland 4 cluster analysis; continental margin; core logging; depositional environment; depositional sequence; hydrocarbon exploration; lithofacies; lithology; lithostratigraphy; Miocene; Ocean Drilling Program; sea level change; sediment chemistry; sequence stratigraphy; shelf sediment; siliciclastic deposit, Atlantic Ocean; New Jersey Margin https://www.scopus.com/inward/record.uri?eid=2-s2.0-84881511164&doi=10.1130%2fGES00913.1&partnerID=40&md5=625c64323d1c35e61551064d1cf68452 cited By 12 J.
