Lake Ohrid is considered to be the oldest existing lake in Europe. Moreover, it has a very high degree of endemic biodiversity. During a drilling campaign at Lake Ohrid in 2013, a 569 m long sediment sequence was recovered from Lake Ohrid. The ongoing studies of this record provide first important information on the environmental and evolutionary history of the lake and the reasons for its high endimic biodiversity.

Many important processes within the global mercury (Hg) cycle operate over thousands of years. Here, we explore the timing, magnitude, and expression of Hg signals retained in sediments of lakes Prespa and Ohrid over the past ∼90 000 years. Divergent signals suggest that local differences in sediment composition, lake structure, and water balance influence the local Hg cycle and determine the extent to which sedimentary Hg signals reflect local- or global-scale environmental changes.

The pollen and dinoflagellate cyst content of 21 surface sediments from the northern Gulf of Mexico is used to test the applicability of three palynological ratios (heterotroph/autotroph, pollen/dinocyst, and pollen/bisaccate ratio) as proxies for marine productivity and distance to the coast/river. Redundancy analysis confirms the suitability of these three ratios, where the H/A ratio can be used as an indicator of primary production, and the P/B ratio best tracks the distance to the coast.

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.

The investigation of a 9 m long sediment core recovered at ca. 300 m water depth demonstrates that cold-water coral mound build-up within the East Melilla Coral Province (southeastern Alboran Sea) took place during both interglacial and glacial periods. Based on the combination of different analytical methods (e.g. radiometric dating, micropaleontology), we propose that corals never thrived but rather developed under stressful environmental conditions.

Levinson-Lessing Lake in northern central Siberia provides an exceptional opportunity to study the evolution of the Earth's magnetic field in the Arctic. This is the first study carried out at the lake that focus on the palaeomagnetic record. It presents the relative palaeointensity and palaeosecular variation of the upper 38 m of sediment core Co1401, spanning ~62 kyr. A comparable high-resolution record of this time does not exist in the Eurasian Arctic.

Anoxia in lakes is a major growing concern. In this study we applied a multiproxy approach combining high-resolution hyperspectral imaging (HSI) pigment data with specific HPLC data to examine the Holocene evolution and main drivers of lake anoxia and trophic state changes. We find that when human impact was low, these changes were driven by climate and natural lake-catchment evolution. In the last 500 years, increasing human impact has promoted lake eutrophication and permanent anoxia.

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.

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.

The mid-Pliocene warm period (mPWP; 3.3–3.0 million years ago) is thought to be the last geological interval with similar atmospheric carbon dioxide concentrations as the present day. Further, the mPWP was 2–3 °C warmer than present, making it a good analogue for estimating the effects of future climate change. Here, we construct a new precise age model for the North Sea during the mPWP, and provide a detailed reconstruction of terrestrial and marine climate using a multi-proxy approach.

Climate changes occur today as they occurred in the past. This study deals with climate changes reconstructed at Lake Ohrid (Albania and FYROM) between 160 000 and 70 000 years ago. Climate reconstruction, based on a high-resolution pollen study, provides quantitative estimates of past temperature and precipitation. Our data show an alternation of cold/dry and warm/wet periods. The last interglacial appears to be characterized by temperatures higher than nowadays.

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 buildup and melting of ice during the early glaciations in the Northern Hemisphere, around 2.5 million years ago, were far shorter in duration than during the last million years. Based on molecular compounds and microfossils from sediments dating back to the early glaciations we show that the temperature on land and in the sea changed simultaneously and was a major factor in the ice buildup in the Northern Hemisphere. These data provide key insights into the dynamics of early glaciations.

The first high-resolution Lake Dojran pollen record for the last 12 500 years is presented. The ecological succession shows Late Glacial steppe vegetation gradually replaced, since 11 500 yr BP, by Holocene mesophilous forests. The first human traces are recorded around 5000 yr BP and increased considerably since the Bronze Age. Pollen data and sedimentological, biomarker and diatom data available from the same core contribute to an understanding of the environmental history of the Balkans.

The hothouse climate of the early Paleogene and the associated violent carbon cycle perturbations are of particular interest to understanding current and future global climate change. Using dinoflagellate cysts and stable carbon isotope analyses, we identify several significant events, e.g., the Paleocene–Eocene Thermal Maximum in sedimentary deposits from the Otway Basin, SE Australia. We anticipate that this study will facilitate detailed climate reconstructions west of the Tasmanian Gateway.

The observed palaeovegetation movement signals probably correspond to several glacial phases of the middle Oligocene and Early Miocene and might be best reflected within peaks of the conifer forests. Glacial phases exposed shallow shelf areas and allowed the spreading of substrate-depending forest formations. Temperature estimates revealing relative stable humid warm temperate conditions. A Sporadic occurred extinct taxon widens the understanding of its distribution pattern during the Cenozoic.

We explored the potential of a sedimentary sequence in Valle d'Aosta (Northern Italy) as a natural archive of hazards. Our results suggest that this sequence is regionally the most sensitive to earthquake shaking with the record of 8 earthquakes over the last ~270 years and that it well represents the regional and (multi-)decennial variability of Mediterranean summer–autumn floods. Hence, this sequence offers a great potential to extend chronicles of regional floods and earthquakes back in time.

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.

Chronology is fundamental in paleoclimatology for understanding timing of events and their origin. In this paper we try to obtain a more detailed chronology for the interval comprised between ca. 140 and 70 ka for the DEEP core in Lake Ohrid using regional independently-dated archives (i.e. speleothems and/or lacustrine succession with well-dated volcanic layers). This allows to insert the DEEP chronology within a common chronological frame between different continental and marine proxy records.

The magnetic record from Lake Ohrid reflects a strong change in geochemical conditions in the lake. Before 320 ka glacial sediments contain iron sulfides, while later glacials are dominated by siderite. Superimposed on this large-scale pattern are climatic induced changes in the magnetic mineralogy. Glacial and stadial sediments are characterized by relative increases of high- vs. low-coercivity minerals which relate to enhanced erosion in the catchment, possibly due to a sparse vegetation.

We use stable isotope data from carbonates to provide a palaeoenvironmental reconstruction covering the last 637 kyr at Lake Ohrid (FYROM/Albania). Our results indicate a relatively stable climate until 450 ka, wetter climate conditions at 400–250 ka, and a transition to a drier climate after 250 ka. This work emphasises the importance of Lake Ohrid as a valuable archive of climate change in the northern Mediterranean region.

Lake Ohrid (FYROM/Albania) is the deepest, largest and oldest lake in Europe. To understand the climatic and environmental evolution of its area, a palynological study was undertaken for the last 500 ka. We found a correspondence between forested/non-forested periods and glacial-interglacial cycles of marine isotope stratigraphy. Our record shows a progressive change from cooler and wetter to warmer and dryer interglacial conditions. This shift is also visible in glacial vegetation.

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.

The long-term response of the flood activity to both Atlantic and Mediterranean climatic influences was explored by reconstructing the Foréant record. Both influences result in a higher flood frequency during past cold periods. Atlantic influences seem to result in more frequent high-intensity flood events during past warm periods, suggesting an increase in flood intensity under the global warming. However, no high-intensity events occurred during the 20th century.

Lake Ohrid is situated in the southern Balkans between Albania and Macedonia. It is a unique ecosystem with remarkable biodiversity and a sediment record of past climates that goes back more than a million years. Detailed reconstructions of past climate development and human alteration of the environment require underpinned and so in this study we go the present-day lake vegetation and catchment soils and test new proxies over one of the known recent cooling events of the region 8200 years ago.

Gamma ray (GR) fluctuations and K values from downhole logging data obtained in the sediments of Lake Ohrid correlate with the global climate reference record (LR04 stack from δ18O) (Lisiecki and Raymo, 2005). GR and K values are considered a reliable proxy to depict glacial-interglacial cycles and document warm, humid and cold, drier periods. A robust age model for the downhole logging data over the past 630kyr was established and will play a crucial role for other working groups.

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.

Lake Vida is one of the largest lakes in the McMurdo dry valleys, Antarctica, and has the thickest known ice cover of any lake on Earth. For the first time, Lake Vida was drilled to a depth of 27m. With depth the ice cover changes from freshwater ice to salty ice interspersed with thick sediment layers. It is hypothesized that the repetition of sediment layers in the ice will reveal climatic and hydrologic variability in the region over the last 1000--3000 years.

A diverse suite of “fossils” associated with the ~1.5 Ga Volyn (Ukraine) kerite was published recently. We show that at least some of them represent modern contamination including plant hairs, pollen, and likely later fungal growth. Comparable diversity is shown to exist in moderm museum dust, calling into question whether any part of the Volyn biota is of biological origin while emphasising the need for scrupulous care in collecting, analysing, and identifying Precambrian microfossils.

Rate-of-change records based on compositional data are ambiguous as they may rise irrespective of the underlying trajectory of ecosystems. We emphasize the importance of characterizing both the direction and the rate of palaeoecological changes in terms of key features of ecosystems rather than solely on community composition. Past accelerations of community transformation may document the potential of ecosystems to rapidly recover important ecological attributes and functions.

The Volyn biota (Ukraine), previously assumed to be an extreme case of natural, abiotic synthesis of organic matter, is more likely a diverse assemblage of fossils from the deep biosphere. Although contamination by modern organisms cannot completely be ruled out, it is unlikely, considering all aspects, i. e. their mode of occurrence in the deep biosphere, their fossilization and mature state of organic matter, their isotope signature, and their large morphological diversity.

This study looked into the regional and global response of planktonic foraminifera to the climate over the last 5 million years, when the Earth cooled significantly. These single celled organisms exhibit the best fossil record available to science. We document an abundance switch from warm water to cold water species as the Earth cooled. Moreover, a closer analysis of certain species may indicate higher fossil diversity than previously thought, which has implications for evolutionary studies.

Deep-living organisms are a major yet poorly known component of ocean biomass. Here we reconstruct the evolution of deep-living zooplankton and phytoplankton. Deep-dwelling zooplankton and phytoplankton did not occur 15 Myr ago, when the ocean was several degrees warmer than today. Deep-dwelling species first evolve around 7.5 Myr ago, following global climate cooling. Their evolution was driven by colder ocean temperatures allowing more food, oxygen, and light at depth.

Benthic foraminifera play a significant role in modern reefal ecosystems mainly due to their symbiosis with photosynthetic microorganisms. Foraminifera were also components of Devonian stromatoporoid coral reefs; however, whether they could have harbored symbionts has remained unclear. We show that Devonian foraminifera may have stayed photosynthetically active, which likely had an impact on their evolutionary radiation and possibly also on the functioning of Paleozoic shallow marine ecosystems.

This paper is a step towards understanding the basal peat ecosystem beneath the North Sea. Plant remains followed parallel sequences. Methane concentrations were low with local exceptions, with the source likely being trapped pockets of millennia-old methane. Microbial community structure indicated the absence of a biofilter and was diverse across sites. Large carbon stores in the presence of methanogens and in the absence of methanotrophs have the potential to be metabolized into methane.

The exploitation of deep-sea sedimentary archive relies on the recovery of mineralized skeletons of pelagic organisms. Planktonic groups leaving preserved remains represent only a fraction of the total marine diversity. Environmental DNA left by non-fossil organisms is a promising source of information for paleo-reconstructions. Here we show how planktonic-derived environmental DNA preserves ecological structure of planktonic communities. We use planktonic foraminifera as a case study.

A comparative analysis of the metagenomes from two 30,000-year-old permafrost samples, one of lake-alluvial origin and the other from late Pleistocene Ice Complex sediments, revealed significant differences within microbial communities. The late Pleistocene Ice Complex sediments (which are characterized by the absence of methane with lower values of redox potential and Fe2+ content) showed both a low abundance of methanogenic archaea and enzymes from the carbon, nitrogen, and sulfur cycles.

We measured the oxygen isotopic composition of Late Jurassic chondrichthyan teeth (sharks, rays, chimaeras) from the Swiss Jura to get ecological information. The main finding is that the extinct shark Asteracanthus (Hybodontiformes) could inhabit reduced salinity areas, although previous studies on other European localities always resulted in a clear marine isotopic signal for this genus. We propose a mainly marine ecology coupled with excursions into areas of lower salinity in our study site.

The Smithian--Spathian boundary was a key event in the recovery of marine environments and ecosystems following the end-Permian mass extinction ~1.5 million years earlier. Our analysis of the Shitouzhai section in South China reveals major changes in oceanographic conditions at the SSB intensification of oceanic circulation leading to enhanced upwelling of nutrient- and sulfide-rich deep waters and coinciding with an abrupt cooling that terminated the Early Triassic hothouse climate.
