Short summary
U–Pb ages of zircon crystals are used to determine the provenance and depositional age of strata of the Triassic Chinle and Moenkopi formations and the Permian Coconino Sandstone of northern Arizona. Primary source regions include the Ouachita orogen, local Precambrian basement rocks, and Permian–Triassic magmatic arcs to the south and west. Ages from fine-grained strata provide reliable depositional ages, whereas ages from sandstones are compromised by zircon grains recycled from older strata.

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.

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.

The Paleocene–Eocene Thermal Maximum (PETM) is the closest geological analog to modern anthropogenic CO2 emissions, but its causes and the responses remain enigmatic. Coastal plain sediments can resolve this uncertainty, but their discontinuous nature requires numerous sites to constrain events. Workshop participants identified 10 drill sites that target the PETM and other interesting intervals. Our post-drilling research will provide valuable insights into Earth system responses.

Climate cycles with millennial periodicities are enigmatic because no Earth external climate forcing exists that operates on millennial timescales. Using a statistical analysis of a famous Greenlandic air temperature record, we show that two disparate energy sources (one astronomical and one centennial) fuel millennial climate variability. We speculate that two distinct Earth internal cryospheric/climatic/oceanic processes are responsible for the transfer of energy to millennial climate cycles.

Oxygen isotopes are used to date marine sediments via similar large-scale ocean patterns over glacial cycles. However, the Arctic Ocean exhibits a different isotope pattern, creating uncertainty in the timing of past Arctic climate change. We find that the Arctic Ocean experienced large local oxygen isotope changes over glacial cycles. We attribute this to a breakdown of stratification during ice ages that allowed for a unique low isotope value to characterize the ice age Arctic Ocean.

Our planet experienced enormous environmental changes in the last 10 million years. Lake Tanganyika is the oldest lake in Africa and its sediments comprise the most continuous terrestrial environmental record for this time period in the tropics. This workshop report identifies key research objectives in rift processes, evolutionary biology, geomicrobiology, paleoclimatology, paleoecology, paleoanthropology, and geochronology that could be addressed by drilling this globally important site.

MexiDrill, the Basin of Mexico Drilling Program, recovered a continuous, high-resolution 400 000 year record of tropical North American environmental change. The field location, in the densely populated, water-stressed, Mexico City region, gives this record particular societal relevance. The record also contains a rich record of volcanic activity; knowledge of the history of the area's explosive volcanic eruptions will improve capacity for risk assessment of future activity.

The Towuti Drilling Project seeks to understand the long-term environmental and climatic history of the tropical western Pacific and to discover the unique microbes that live in metal-rich sediments. To accomplish these goals, in 2015 we carried out a scientific drilling project on Lake Towuti, located in central Indonesia. We recovered over 1000 m of core, and our deepest core extended 175 m below the lake floor and gives us a complete record of the lake.

We report on a planned Trans-Amazon Drilling Project (TADP) that will continuously sample Late Cretaceous to modern sediment in a transect along the equatorial Amazon of Brazil, from the Andean foreland to the Atlantic Ocean. The TADP will document the evolution of the Neotropical forest and will link biotic diversification to changes in the physical environment, including climate, tectonism, and landscape. We will also sample the ca. 200Ma basaltic sills that underlie much of the Amazon.

In the frame of the DOVE (Drilling Overdeepened Alpine Valleys) project and with the support of the International Continental Scientific Drilling Program (ICDP), we drilled and recovered a 252 m long sediment core from the Basadingen Through. The Basadingen Trough, once eroded by the Rhine glacier during several ice ages, reaches over 300 m under the modern landscape. The sedimentary filling represents a precious scientific archive for understanding and reconstructing past glaciations.

Western North American contains accessible and under-recognized paleolake records that hold the keys to understanding the drivers of wetter conditions in Pliocene Epoch subtropical drylands worldwide. In a 2021 ICDP workshop, we chose five paleolake basins to study that span 7° of latitude in a unique array able to capture a detailed record of hydroclimate during the Early Pliocene warm period and subsequent Pleistocene cooling. We propose new drill cores for three of these basins.

Previous glaciations eroded below the ice deep valleys in the Alpine foreland, which, with their sedimentary fillings, witness the timing and extent of these glacial advance–retreat cycles. Drilling such sedimentary sequences will thus provide well-needed evidence in order to reconstruct the (a)synchronicity of past ice advances in a trans-Alpine perspective. Eventually these data will document how the Alpine foreland was shaped and how the paleoclimate patterns varied along and across the Alps.

A scientific drilling was conducted into a bedrock trough (overdeepening) in Bern-Bümpliz (Switzerland) in an effort to advance the knowledge of the Quaternary prior to 150 000 years ago. We encountered a 208.5 m-thick succession of loose sediments (gravel, sand and mud) in the retrieved core and identified two major sedimentary sequences (A: lower, B: upper). The sedimentary suite records two glacial advances and the subsequent filling of a lake sometime between 300 000 and 200 000 years ago.

How much of the West Antarctic Ice Sheet will melt and how quickly it will happen when average global temperatures exceed 2 °C is currently unknown. Given the far-reaching and international consequences of Antarctica’s future contribution to global sea level rise, the SWAIS 2C Project was developed in order to better forecast the size and timing of future changes.

Earth has experienced remarkable climate–environmental changes in the last 65 million years. The Weihe Basin with its 6000–8000 m infill of a continuous sedimentary sequence gives a unique continental archive for the study of the Cenozoic environment and exploration of deep biospheres. This workshop report concludes key objectives of the two-phase Weihe Basin Drilling Project and the global significance of reconstructing Cenozoic climate evolution and tectonic–monsoon interaction in East Asia.

The events of the Permian — the orogenies, biospheric turnovers, icehouse and greenhouse antitheses, and Mars-analog lithofacies — boggle the imagination and present us with great opportunities to explore Earth system behavior. Here we outline results of workshops to propose continuous coring of continental Permian sections in western (Anadarko Basin) and eastern (Paris Basin) equatorial Pangaea to retrieve continental records spanning 50 Myr of Earth's history.

This paper summarizes a workshop held in Parker, AZ, USA, to discuss planned scientific drilling in the Miocene(?) or early Pliocene Bouse Formation, a controversial deposit (of lacustrine, marine, or some hybrid origin) found in the lower Colorado River valley. The drilling project is intended to address this controversy as well as shed light on Pliocene climates of southwestern North America during an important period of past climate change.

The CONOSC (COring the NOrth Sea Cenozoic) project brings scientists together that aim at scientific drilling of the north-western European marginal seas where in the last 65 million years the influence of sea and land was recorded continuously in the sediments. The subsiding area is ideally suited for detailed study of the relations between changing climate, biodiversity, and changing land masses. The report discusses the ICDP workshop outcome and overall project aims.

As a pilot study for a possible depth-drilling project, an 82m long sedimentary succession was retrieved from the Fucino Basin, central Apennines, which hosts ca. 900m of lacustrine sediments. The acquired paleoclimatic record, from the retrieved core, spans the last 180ka and reveals noticeable variations related to the last two glacial-interglacial cycles. In light of these results, the Fucino sediments are likely to provide one of the longest continuous record for the last 2Ma.

We report on a planned Trans-Amazon Drilling Project (TADP) that will continuously sample Late Cretaceous to modern sediment in a transect along the equatorial Amazon of Brazil, from the Andean foreland to the Atlantic Ocean. The TADP will document the evolution of the Neotropical forest and will link biotic diversification to changes in the physical environment, including climate, tectonism, and landscape. We will also sample the ca. 200Ma basaltic sills that underlie much of the Amazon.

Short summary
The Colorado Plateau Coring Project-1 recovered ~ 850 m of core in three holes at two sites in the Triassic fluvial strata of Petrified Forest National Park, AZ, USA. The cores have abundant zircon, U-Pb dateable layers (210–241 Ma) that along with magnetic polarity stratigraphy, validate the eastern US-based Newark-Hartford astrochronology and timescale, while also providing temporal and environmental context for the vast geological archives of the Triassic of western North America.
