Professor Renato Almeida from the University of São Paulo and Professor Felipe Torres from the University of Sergipe arrived to assist Isaac Bezerra in core handling activities and in communication with Geosol management on site, providing updates to the executive committee.

Professor Negri has been crucial in planning drilling activities in the Acre Basin. He has contributed to advancing research in paleozoology in the state of Acre since 1988. His energy and dedication to work during corehandling activities are contagious.

Pieces of wood debris are primarily fibrous or flaky. The sand associated with them is high sulfur (S) coal linked to the organic matter itself, a phenomenon commonly observed in coal deposits. Discussions are ongoing regarding the occurrence of high-sulfur coal deposited in brackish environments or not.

The core diameter is 63.5 mm. We are using split liners. The depth is around 865 m.

The sediment sampling on site is intended to serve as a preliminary analysis of the luminescence methods conducted by André Sawakuchi.

The mud fluid engineer added sodium chloride to the drilling mud fluid. The salt causes damage to the iron and metal tools on site.

Francisco Negri from Federal University of Acre and Clauses Sergio, the company man accompanying the activities.

During the coring through the cementation zone, the drill bite core from previous stuck drill pipe was cored.

Felipe Figueiredo arrived and accompanied the measurements on the piezometers.

The stratigraphic description helps to understand the geometry of the sand bodies cored on the drill site.

Fabiano Pupim sampled the Juruá River sandbar in the Pucalpa locality. The quartz sedimentological sample will be used for cosmogenic analysis.

While the drilling company is finishing the cementation phase, the team on site is conducting fieldwork on fluvial terraces near the drill site city.
These fluvial terraces are an important piece for understanding the evolution of the landscape of western Amazonia.

After the project manager's inspection, the condition of the core samples stored in the warehouse is being discussed.
The executive committee is concerned that it may be microbial growth. However, the dark coloration is related to the decomposition of the drilling fluid.

The caliper probe was used to check for overwash below the stuck pipeline. An overwash section was identified, and cementing is required.
None of the team members in the operation are geophysicists. The team on site received online guidance from geophysicist Tacio Bicudo.

Fieldwork in the Boa Fé region (white sands, understanding of deposits), with OSL collection via auger.

Field in Serra do Divisor (understanding of regional geology), with OSL and cosmogenic collection and description of some outcrops.

Water collection in piezometers installed in the region of Rodrigues Alves and Cruzeiro do Sul.

Professor Ingo and Isaac accompanied the cementing of the well and the cleaning of the mud disposal tank.

Optically stimulated luminescence (OSL) thermochronometry and cosmogenic collection as well as description in the Prophet community.

Arrival of Prof. Fabiano and return of Isaac. Birthday party for Angela and farewell from Elisa.

Mapping to create a digital elevation model of the area around the probe.

Placement of a piezometer in the forest near Mr. Tadeu's property in Cruzeiro do Sul.

Arrival of cores 327 and 328 on the night shift.

Pedro and Fernanda analyzed the mud used in drilling to understand what caused the bad smell.

New shift members went to the probe to learn their roles.

Checking the cores at the warehouse.

Dailson installing greenhouse gas chambers on the abandoned meander of the Jurua River.

Our company man, Clauses Sergio, checking drilling operations very carefully.

The section pipe is being pulled through during the night shift.

Time for installing piezometers at 8 m deep with Ingo, Pedro, and Elisa.

Greenhouse gas monitoring close to the drilling site.

Sampling of Jurua River floodplain deposits.

Roney and Ingo are preparing piezometers for groundwater sampling as we wait for drilling to resume.

Today we had visitors from Germany for the channel “ZDF Info” in the series "Wonders of Nature - on the traces of the history of the Earth" and we showed them our day-to-day life at the drill site.

Time for downhole sound logging.

Leaving the drill site at shift change.

Fernanda is describing the core catcher lithology as Roney updates the drilling information.

Today we are adding new members to our science team. Elisa Piispa came all the way from Iceland to Acre and she is ready to curate new cores.

Look at how beautiful our drill site is at night time.

Check out the beautiful gypsum crystal that we drilled today.

Some tidying up is in order. Time to take these cores from the drilling site to the warehouse.

Day and night shift gathering at the drilling site.

Today, Carlos, Pedro, and Leonardo went upstreaming the Jurua River for some drone imaging.

As we wait for new cores to come, some members of the team went to describe the modern fluvial bars of the Jurua River.

More cores are coming as we have reached over 700 m drilled!

Check out the textured 3D model of our drilling site produced with the drone flights conducted earlier this week. This model is available on the Sketchfab portal at this link: https://sketchfab.com/3d-models/tadp-ac-01-9f07f7bdd91c4d8a997e593e55b2bb00

Today we had a chat with Cunha Vasconcelos School students, where our team showed the TADP project and our day-to-day life at the drill site.

Leonardo is surveying the drill site for 3D image modeling.

Professors Carlos D'Apolito from Acre Federal University (UFAC), Cleverson Guizan from Fluminense Federal University (UFF), and Fernanda Rodrigues, a post-doctoral researcher from the University of São Paulo (USP), have joined the team.
