Global Cycles and Cataclysmic Events

Drilling the subsurface of lakes as archives of global cycles and cataclysmic events

The advantage of being able to drill superb long, continuous and high-resolution archives, allows numerous unprecedented reconstructions of climate change and natural hazards that offer a high societal relevance. However, these advantages are not easy to be unraveled, as complex logistical and technologic challenges for drilling operations need to be overcome, in particular as many drilling targets were in remote and climatologically harsh areas. These 'aqueous' drilling operations on large and remote lakes required a steep learning curve in order to maximize scientific output of these endeavors.

All of the projects implied a substantial outreach and societal component for the local community, as new data, technologies and international contacts were introduced to areas often not very well developed. This role of ICDP is important, and the international drilling community needs to be aware of its responsibility towards these local hosts and populations, in particular in the context of the respective educational and research structures.

Lake-drilling targets often contain dual objectives, as the sedimentary column as well as the rock substrate provide independent scientific themes. Natural hazards were amongst the objectives for most lakes, many of them representing indeed cataclysmic events, notably meteorite impacts, earthquakes and volcanic eruptions. Climate changes stored in the succession of lacustrine sediments may be of rapid or more gradual nature. Many of the globally-known events (i.e. from marine and ice-core records) are also recorded - their nature, structure and amplitude often differ substantially from one area to another, so that the regional climate and its teleconnections can be studied in more detail as would possible without ICDP drilling. Special focus is given to the paleolimnologic, paleobiologic states contained in the sedimentary lithologies as well as the subsurface biosphere. The majority of the targeted lakes allows in particular a detailed reconstruction of past hydrologic states, and thus offer new insights into atmospheric circulation patterns. The increasing and still growing number of such long and continuous paleoclimate records and lake drilling projects, at the scale of several glacial-interglacial cycles and covering a wide range of lake types, will in detail reconstruct climate teleconnections between all continents and thus refine significantly underlying mechanisms controlling global climate.
