We present initial results from a 650 m long core of Late Triasssic to Early Jurassic (190–202 Myr) sedimentary strata from the Cheshire Basin, UK, which is shown to be an exceptional record of Earth evolution for the time of break-up of the supercontinent Pangaea. Further work will determine periodic changes in depositional environments caused by solar system dynamics and used to reconstruct orbital history.

Here we review current progress in LA-ICP-MS U–Pb carbonate geochronology and present strategies for acquisition and interpretation of carbonate U–Pb dates. We cover topics from imaging techniques and U and Pb incorporation into calcite to potential limitations of the method – disequilibrium and isotope mobility. We demonstrate the incorporation of imaging and compositional data to help refine and interpret U–Pb dates. We expect this paper to become a
go-toreference paper for years to come.

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.

Geologists can decipher the past climates and thus better understand how future climate change may affect the Earth's complex systems. In this paper, we report on a workshop held in Longyearbyen, Svalbard, to better understand how rocks in Svalbard (an Arctic archipelago) can be used to quantify major climatic shifts recorded in the past.

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 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.

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.
