A total of 42 Earth scientists from 14 countries met in Gioia dei Marsi, central Italy, on 23 to 27 October 2023 to explore the potential for deep drilling of the thick lake sediment sequence of the Fucino Basin. The aim was to reconstruct the history of climate, ecosystem, and biodiversity changes and of the explosive volcanism and tectonics in central Italy over the last 3.5 million years, constrained by a detailed radiometric chronology.

The Deep Drilling in the Turkana Basin project seeks to determine the relative impacts of tectonics and climate on eastern African ecosystems. To organize goals for coring, we hosted a workshop in Nairobi, Kenya, which focused on how a 4 Myr sedimentary core from Turkana will uniquely address research objectives related to basin evolution, past climates and environments, and modern resources. We concluded that a Pliocene to modern record is best accomplished through a two-phase drilling project.

In August 2022, 65 scientists from 13 countries gathered in Antigua, Guatemala, for a workshop, co-funded by the US National Science Foundation and the International Continental Scientific Drilling Program. This workshop considered the potential of establishing a continental scientific drilling program in the Lake Izabal Basin, eastern Guatemala, with the goals of establishing a borehole observatory and investigating one of the longest continental records from the northern Neotropics.

We measured the surface area of minerals in two 21 m cores from soil to bedrock to test hypotheses on the formation of the surface area of weathered rock. A sharp increase in high-surface-area secondary minerals extended from 3 m to the ground surface. Half the total surface area was from corroded iron minerals, which form in the presence of oxygen, even though corroded iron comprised less than 0.1 % of the rock. Element removal by rock dissolution started at 7 m but did not form new minerals.

Short summary
We present initial results from the upper 450 m of ER-1, a legacy core collected from modern-day Bears Ears National Monument, Utah, USA. This section contains a relatively complete record of Upper Carboniferous to Early Permian sediments, providing a unique window on Earth's last icehouse–hothouse transition. Ongoing research will tie our results to important fossil sites, allowing us to better understand how this climate shift contributed to the evolution of terrestrial life.
