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.

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.

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.

This paper presents the first comprehensive compilation of diatom oxygen isotope records in lake sediments (δ18OBSi), supported by lake basin parameters. We infer the spatial and temporal coverage of δ18OBSi records and discuss common hemispheric trends on centennial and millennial timescales. Key results are common patterns for hydrologically open lakes in Northern Hemisphere extratropical regions during the Holocene corresponding to known climatic epochs, i.e. the Holocene Thermal Maximum.

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 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.

Lakes act as important stores of organic carbon and inorganic sediment material. This study provides a first investigation into carbon and sediment accumulation and storage within an Arctic glacial lake from Far East Russia. It shows that major shifts are related to palaeoclimate variation that affects the development of the lake and its surrounding catchment. Spatial differences to other lake systems from other regions may reflect variability in processes controlled by latitude and altitude.

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.

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.

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 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.

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.

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.

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.

Fossil bivalves are an excellent climate archive due to their rapidly forming growth increments and long lifespan. Here, we show that the extinct bivalve species Angulus benedeni benedeni can be used to reconstruct past temperatures using oxygen and clumped isotopes. This species has the potential to provide seasonally resolved temperature data for the Pliocene to Oligocene sediments of the North Sea basin. In turn, these past climates can improve our understanding of future climate change.

I found a good correlation between the mass extinction magnitudes of animals and surface temperature anomalies. The relation is good regardless of the difference between warming and cooling. Marine animals are more likely than tetrapods to become extinct under a habitat temperature anomaly. The extinction magnitudes are marked by abrupt global surface temperature anomalies and coincidental environmental changes associated with abrupt high-energy input by volcanism and impact.

The shell of the California mussel contains alternating dark and light calcium carbonate increments that record whether the shell was growing normally under optimal conditions (light) or slowly under sub-optimal conditions (dark). However, the timing and specific environmental controls of growth band formation have not been tested. We investigated these controls and found links between stable seawater temperatures and light bands and highly variable or extreme temperatures and dark bands.

We explore the sensitivity of cold-water corals (CWCs) to environmental changes utilizing a multiproxy approach on a coral-bearing sediment core from off southeastern Brazil. Our results reveal that over the past 160 kyr, CWCs flourished during glacial high-northern-latitude cold events (Heinrich stadials). These periods were associated with anomalous wet phases on the continent enhancing terrigenous nutrient and organic-matter supply to the continental margin, boosting food supply to the CWCs.

Mechanisms of atmospheric CO2 growth by 20 ppm from 6000 BCE to the pre-industrial period are still uncertain. We apply the Earth system model MPI-ESM-LR for two transient simulations of the climate–carbon cycle. An additional process, e.g. carbonate accumulation on shelves, is required for consistency with ice-core CO2 data. Our simulations support the hypothesis that the ocean was a source of CO2 until the late Holocene when anthropogenic CO2 sources started to affect atmospheric CO2.

To gain a better understanding of climate and marine biogeochemistry variations over the last 9500 years (the Holocene), we performed non-accelerated model simulations with a global coupled climate and biogeochemistry model forced by orbital parameters and atmospheric greenhouse gases. One main outcome is an increase in the volume of the eastern equatorial Pacific oxygen minimum zone, driven by a slowdown of the large-scale circulation.

We show that plant functional diversity significantly affects climate–vegetation interaction and the climate–vegetation system stability in response to external forcing using a series of coupled land–atmosphere simulation. Our findings raise the question of how realistically Earth system models can actually represent climate–vegetation interaction, considering the incomplete representation of plant functional diversity in the current generation of land surface models.

A high-resolution dynamical model was used to give the first simulation of the distribution of natural and anthropogenic radiocarbon (14C) across the whole Mediterranean Sea. The model correctly simulates the main features of 14C distribution during and after the bomb perturbation. The results demonstrate the major influence of the flux of Atlantic water through the Strait of Gibraltar, and a significant increase in 14C in the Aegean deep water during the Eastern Mediterranean Transient event.

We have analysed the rate of calcification of fossil reef corals. These measurements are important, because the rate of formation of the skeleton depends on the physical environment in which the corals lived. The rates of skeletal calcification of the fossils were approximately 50 % lower than they are in extant reef corals. This is a likely effect of high water temperatures and/or low carbonate saturation of the water – factors that will also affect coral growth by future global warming.

We reconstruct spatiotemporal variations in biomass burning since the Last Glacial Maximum (LGM) using the Global Charcoal Database version 3 (including 736 records) and a method to grid the data. LGM to late Holocene burning broadly tracks global and regional climate changes over that interval. Human activities increase fire in the 1800s and then reduce it for most of the 20th century. Burning is now rapidly increasing, particularly in western North America and southeastern Australia.

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.

Short summary
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.
