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.

A workshop was held in Basel, Switzerland, to discuss the scientific opportunities for evolutionary biology, paleobiology and paleoecology of a drilling project at Lake Tanganyika, one of the oldest and most biodiverse lakes on Earth. A record of the numerous endemic organisms collected from the lake coupling body fossils, environmental history and potentially aDNA or ancient protein records would be transformative for understanding evolution in isolation and the biogeographic history of Africa.

Archaeal molecular fossils (tetraethers) have been used around the globe to track changes in climate. Little is known about archaeal response to environmental change in soda lakes, especially lakes influenced by hydrothermal inputs. For the first time in Lake Magadi, we show tetraethers tracking abrupt changes in methane and non-methane producers due to hydrothermal inputs to the lake. This study provides insight into the role of hydrothermal water sources and methane production in soda lakes.

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.

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.

With regard to global warming, an understanding of past temperature changes is becoming increasingly important. Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are membrane lipids used globally to reconstruct lake water temperatures. In the Bale Mountains lakes, we find a unique composition of brGDGT isomers. We present a modified local calibration and a new high-altitude temperature reconstruction from the Horn of Africa spanning the last 12.5 kyr.

We present a reconstruction of winter–spring temperatures developed using organic proxies preserved in well-dated lake sediments from southwest Iceland to assess seasonal temperature changes in the North Atlantic region over the last 2000 years. The gradual warming trend observed in our record is likely influenced by sea surface temperatures, which are sensitive to changes in ocean circulation and seasonal insolation, during the winter and spring season.

We present a curated database of western North American Holocene paleoclimate records, which have been screened on length, resolution, and geochronology. The database gathers paleoclimate time series that reflect temperature, hydroclimate, or circulation features from terrestrial and marine sites, spanning a region from Mexico to Alaska. This publicly accessible collection will facilitate a broad range of paleoclimate inquiry.

Ferruginous lakes experience restricted primary production due to phosphorus trapping by ferric iron oxides under oxic conditions. We report the presence of large crystals of vivianite, a ferrous iron phosphate, in sediments from Lake Towuti, Indonesia. We address processes of P retention linked to diagenesis of iron phases. Vivianite crystals had light Fe2+ isotope signatures and contained mineral inclusions consistent with antecedent processes of microbial sulfate and iron reduction.

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 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 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.

Cushion peatlands are versatile climate archives for the study of past environmental changes. We present the environmental history for the last 2100 years of Cerro Tuzgle peatland, which is located in the NW Argentine Puna. The results reflect prominent late Holocene climate anomalies and provide evidence that Northern Hemisphere climate oscillations were extensive. Volcanic forcing at the beginning of the 19th century seems to have had an impact on climatic settings in the Central Andes

Lake Ohrid (Macedonia, Albania) is thought to be more than 1.2 million years old. To recover a long paleoclimate record for the Mediterranean region, a deep drilling was carried out in 2013 within the scope of the Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project. Here, we present lithological, sedimentological, and (bio-)geochemical data from the upper 247.8 m composite depth of the overall 569 m long DEEP site record.

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.

Around half of all pyrogenic carbon (charcoal+soot) derived from wildfires comes from semi-annual burning of tropical savannas. This pyrogenic carbon is significant because it is a component of global aerosols capable of modulating the greenhouse effect and is resistant to degradation. We use controlled field burns in northern Australian savannas to determine how much pyrogenic carbon is formed, how much of this is recalcitrant and how it is partitioned between ground residues and airborne soot.

Lake Victoria is home to the largest human population surrounding any lake in the world and provides critical resources across eastern Africa. It is vital to understand the connection between the lake and climate and how it has changed through its history, but to do so we need a complete archive of the sedimentary record. To evaluate the Lake Victoria basin as a potential drilling target, ~50 scientists met in Dar es Salaam, Tanzania, in July 2022 for the Lake Victoria Drilling Project workshop.

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.

In 2016, an international team cored Orakei Basin, a former volcanic crater lake in the Auckland Volcanic Field. The retrieved sediment cores are over 100 m long from the basal volcanic eruptive material to the topmost marine mud. The lake sediment sequence of ca. 80 m will be used to reconstruct paleo-environmental and -climatic changes of the region over the last ca. 120 000 years and to reconstruct the history of volcanic eruptions in Auckland through ash layers in the stratigraphic record.

The Tibetan Plateau is of relevance as it provides water to a large portion of the Asian population. To define parameters for climate change scenarios it is necessary to improve the knowledge about past climatic changes in this area. Sedimentary archives like Nam Co provide the possibility to get such information. In order to explore opportunities of an ICDP drilling at Nam Co, 40 scientists met in May 2018. Everybody agreed on the need to drill this site with a sediment thickness > 1 km (> 1 Ma).

A new annually resolvable sedimentary record of southern hemisphere climate has been recovered from Lake Ohau, South Island, New Zealand. The Lake Ohau Climate History (LOCH) Project acquired cores from two sites that preserve an 80 m thick sequence of laminated mud that accumulated since the lake formed ~ 17 000 years ago. Cores were recovered using a purpose-built barge and drilling system designed to recover soft sediment from relatively thick sedimentary sequences at water depths up to 100 m.

CHADRILL aims to recover a sedimentary core spanning the Miocene–Pleistocene sediment succession of Lake Chad through deep drilling. This record will provide significant insights into the modulation of orbitally forced changes in northern African hydroclimate under different climate boundary conditions and the most continuous climatic and environmental record to be compared with hominid migrations across northern Africa and the implications for understanding human evolution.

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.
