Despite its importance in the global climate, our knowledge of Antarctic sea-ice changes throughout the last glacial–interglacial cycle is extremely limited. As part of the Cycles of Sea Ice Dynamics in the Earth system (C-SIDE) Working Group, we review marine- and ice-core-based sea-ice proxies to provide insights into their applicability and limitations. By compiling published records, we provide information on Antarctic sea-ice dynamics over the past 130 000 years.

This study analyses physical and biogeochemical data collected in the East Australian Current (EAC) to understand variability in the nutrient-poor surface waters. The distribution of nutrients in the water column is influenced by seasonal flow and the EAC's position. An inshore EAC has a deeper nutricline and lower nutrient concentrations compared to an offshore EAC position. This has implications for the marine ecosystems along the coastline.

New tephra layer and microsiliceous assemblages are identified. Sediment records are contextualized for the Sabrina Coast continental rise chronological and paleoclimatic context. Some in-depth studies on margin instabilities, tephrochronology, and biostratigraphic/paleoenvironmental and sedimentary evolution are suggested. We performed this study to implement knowledge on the Antarctic biochronostratigraphy and microsiliceous sedimentation and benefited from international-level collaboration.

We quantify sea surface temperature (SST) in the past Southern Ocean using the diatom Fragilariopsis kerguelensis that displays variable population with SST. We explore the use of this relatively new proxy by applying it to sediment assemblages from the Sabrina Coast and Amundsen Sea. We find that Amundsen Sea and Sabrina Coast F. kerguelensis populations are different from each other. An understanding of F. kerguelensis dynamics may help us generate an SST proxy to apply to ancient sediments.

Short summary
The diatom-bound nitrogen isotope proxy is used to study how efficiently diatoms in the Southern Ocean help to remove CO2 from the atmosphere, but may be biased by different diatom species. We examine a specific type of diatom, Chaetoceros resting spores (CRS), commonly preserved in Southern Ocean sediments. We find that CRS record surprisingly low δ15NDB values compared to other diatoms, yet changes in their relative abundance over time does not significantly bias previously published records.

Sea ice is important to stabilize the ice sheet in Antarctica. To understand how the global climate and sea ice were related in the past we looked at ancient molecules (IPSO25) from sea-ice algae and other species whose dead cells accumulated on the ocean floor over time. With chemical analyses we could reconstruct the history of sea ice and ocean temperatures of the past 14 000 years. We found out that sea ice became less as the ocean warmed, and more phytoplankton grew towards today's level.

This study uses diatom assemblages, biogenic silica and Si/Al data over the last 140 kyr from core TAN1302-44 (64°54' S, 144°32' E) to define glacial-to-interglacial paleoenvironments near Antarctica with respect to sea ice duration and ocean circulation. It has found that the sea ice season increased gradually during the last glacial, reaching a maximum before decreasing at the end of MIS 2. Following this, Circumpolar Deep Water increased relative to other times prior to ice sheet retreat.

Algae preserved in seafloor sediments have allowed us to reconstruct how Antarctic sea ice has varied between cold and warm time periods in the last 130 000 years. The patterns and timings of sea-ice increase and decrease vary between different parts of the Southern Ocean. Sea ice is most sensitive to changing climate at the external edges of Southern Ocean gyres (large areas of rotating ocean currents).

Stable isotope ratios of foraminiferal shells from deep-sea sediments preserve key information on the variability of ocean circulation and ice volume. We present the first global atlas of harmonized raw downcore oxygen and carbon isotope ratios of various planktonic and benthic foraminiferal species. The atlas is a foundation for the analyses of the history of Earth system components, for finding future coring sites, and for teaching marine stratigraphy and paleoceanography.

Climate models are used to predict future climate changes and as such, it is important to assess their performance in simulating past climate changes. We analyze seasonal sea-ice cover over the Southern Ocean simulated from numerical PMIP3, PMIP4 and LOVECLIM simulations during the Last Glacial Maximum (LGM). Comparing these simulations to proxy data, we provide improved estimates of LGM seasonal sea-ice cover. Our estimate of summer sea-ice extent is 20 %–30 % larger than previous estimates.

We provide new winter sea ice and summer sea surface temperature estimates for marine core TAN1302-96 (59° S, 157° E) in the Southern Ocean. We find that sea ice was not consolidated over the core site until ~65 ka and therefore believe that sea ice may not have been a major contributor to early glacial CO2 drawdown. Sea ice does appear to have coincided with Antarctic Intermediate Water production and subduction, suggesting it may have influenced intermediate ocean circulation changes.

Algae preserved in marine sediments have allowed us to reconstruct how much winter sea ice was present around Antarctica during a past time period (130 000 years ago) when the climate was warmer than today. The patterns of sea-ice increase and decrease vary between different parts of the Southern Ocean. The Pacific sector has a largely stable sea-ice extent, whereas the amount of sea ice in the Atlantic sector is much more variable with bigger decreases and increases than other regions.

The Totten Glacier (Sabrina Coast, East Antarctica) has undergone significant retreat in recent years, underlining its sensitivity to climate change and its potential contribution to global sea-level rise. The melting process is strongly influenced by ocean dynamics and the spatial distribution of water masses appears to be linked to the complex morpho-bathymetry of the area, supporting the hypothesis that downwelling processes contribute to shaping the architecture of the continental margin.

We explore the potential for the use of carbon isotopes of algal fatty acid as a new proxy for past primary productivity in Antarctic coastal zones. Coastal polynyas are hotspots of primary productivity and are known to draw down CO2 from the atmosphere. Reconstructions of past productivity changes could provide a baseline for the role of these areas as sinks for atmospheric CO2.

Climate models struggle to simulate a LGM ocean circulation in agreement with paleotracer data. Using a set of simulations, we test the impact of boundary conditions and other modelling choices. Model–data comparisons of sea-surface temperatures and sea-ice cover support an overall cold Southern Ocean, with implications on the AMOC strength. Changes in implemented boundary conditions are not sufficient to simulate a shallower AMOC; other mechanisms to better represent convection are required.

We present a multi-proxy record of Holocene glacial meltwater input, sediment transport, and sea-ice variability off East Antarctica. Our record shows that a rapid Antarctic sea-ice increase during the mid-Holocene (~ 4.5 ka) occurred against a backdrop of increasing glacial meltwater input and gradual climate warming. We suggest that mid-Holocene ice shelf cavity expansion led to cooling of surface waters and sea-ice growth, which slowed basal ice shelf melting.

We present a new and highly resolved glacial record of nitrate and calcium from a deep ice core obtained from Roosevelt Island, West Antarctica. Our data show a dependent association among nitrate and non-sea salt calcium (mineral dust) as observed previously in East Antarctica. The spatial pattern indicates that mineral dust is scavenging nitrate from the atmosphere and the westerlies are dispersing the dust-bound nitrate across Antarctica, making nitrate a potential paleo-westerly wind proxy.

Radiolarians are marine micro-organisms that produce a siliceous shell that is preserved in the fossil record and can be used to reconstruct past climate variability. However, their study is only possible after a time-consuming manual selection of their shells from the sediment followed by their individual identification. Thus, we develop a new fully automated workflow consisting of microscopic radiolarian image acquisition, image processing and identification using artificial intelligence.

A record of past sea temperature in the Indian sector of the Southern Ocean, spanning the last 14 200 years, has been developed by analysis of fossil diatoms in marine sediment. During the late deglaciation the reconstructed temperature changes were highly similar to those over Antarctica, most likely due to a reorganisation of global ocean and atmospheric circulation. During the last 11 600 years temperatures gradually cooled and became increasingly variable.

Atmospheric CO2 is key for climate change. CO2 is lower during the oldest warm period of the last million years, the interglacials, than during the most recent ones (since 430 000 years ago). This difference has not been explained yet, but could be due to changes of ocean circulation. We test this hypothesis and the role of vegetation and ice sheets using an intermediate complexity model. We show that only small changes of CO2 can be obtained, underlying missing feedbacks or mechanisms.

Diatoms and biomarkers have been recently used for palaeoclimate reconstructions in the Southern Ocean. Few sediment-based ecological studies have investigated their relationships with environmental conditions. Here, we compare high-resolution sedimentary records with meteorological data to study relationships between our proxies and recent atmospheric and sea surface changes. Our results indicate that coupled wind pattern and sea surface variability act as the proximal forcing at that scale.

Radiolarian taxa with high-latitude affinities are present from at least the middle Eocene in the SW Pacific and become very abundant in the late Eocene at all investigated sites. A short incursion of low-latitude taxa is observed during the MECO and late Eocene warming event at Site 277. Radiolarian abundance, diversity and taxa with high-latitude affinities increase at Site 277 in two steps in the latest Eocene due to climatic cooling and expansion of cold water masses.

Understanding how early farmers adapted to their environments is important regarding how we respond to the changing climate. Here, we present wood charcoal records from northwestern China to explore human–environmental interactions. Our data suggest that people started managing chestnut trees around 4600 BP and cultivating fruit trees and transporting conifers from 3500 BP. From 2500 BP, people established horticultural systems, showing that they actively adapted to the environment.

One of the main uncertainties related to future climate change has to do with how aerosols interact with climate. Dust is the most abundant aerosol in the atmosphere by mass. In order to better understand the links between dust and climate, we can turn to geological archives of ancient dust. Paleo±Dust is a compilation of measured values of the paleo-dust deposition rate. We can use this compilation to guide climate models so that they better represent dust–climate interactions.

We estimate an average (stack) of Western Pacific Warm Pool (WPWP) sea surface climate records over the last 800 kyr from 10 ocean sediment cores. To better understand glacial–interglacial differences between the tropical WPWP and high-latitude climate change, we compare our WPWP stack to global and North Atlantic deep-ocean stacks. Although we see similar timing in glacial–interglacial change between the stacks, the WPWP exhibits less amplitude of change.

This paper focuses on volcanic ash (tephra) in European annually laminated (varve) lake records from the period 25 to 8 ka. Tephra enables the synchronisation of these lake records and their proxy reconstructions to absolute timescales. The data incorporate geochemical data from tephra layers across 19 varve lake records. We highlight the potential for synchronising multiple records using tephra layers across continental scales whilst supporting reproducibility through accessible data.

During the last glacial period, cold conditions associated with changes in atmospheric circulation resulted in the deposition of widespread loess. It seems that the phases of loess accumulation were not strictly synchronous. To test this hypothesis, the chronology of loess deposition in different regions of Europe was studied by recalculating 1423 luminescence ages in a database. Our study discusses the link between the main loess sedimentation phases and the maximal advance of glaciers.

Volcanism is a key driver of climate. Based on ice cores from Greenland and Antarctica, we reconstruct its climate impact potential over the Holocene. By aligning records on a well-dated chronology from Antarctica, we resolve long-standing inconsistencies in the dating of past volcanic eruptions. We reconstruct 850 eruptions (which, in total, injected 7410 Tg of sulfur in the stratosphere) and estimate how they changed the opacity of the atmosphere, a prerequisite for climate model simulations.

Using microfossils to gauge the age of rocks and sediments requires an accurate age of their first (origination) and last (extinction) appearances. But how do you know such ages can then be applied worldwide? And what causes regional differences? This paper investigates the regional consistency of ranges of species of a specific microfossil group, organic-walled dinoflagellate cysts. This overview helps in identifying regional differences in the stratigraphic ranges of species and their causes.

Changes in sea level during Marine Isotope Stage (MIS) 5e are comparable to modern sea levels in our global climate. Contributing to the World Atlas of Last Interglacial Shorelines (WALIS), this paper reviewed data from over 70 studies detailing sea-level markers for MIS 5e around Japan. Most sea-level markers were found as marine terraces and are often dated by comparison to dated volcanic ash or sediment layers, which has connected Japan’s landforms to global patterns of sea-level change.

In this paper, we have compiled data for southeastern South America. There are landforms that indicate that sea level was 5 to 25 m higher than present during this time period. However, the quality of these data is hampered by limitations on elevation measurements, chronology, and geological descriptions.

The Last Interglacial (129–116 ka) experienced global temperatures and sea levels higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) are uncertain. We report a global network of sea surface temperatures. We find mean global annual temperature anomalies of 0.2 ± 0.1˚C and an early maximum peak of 0.9 ± 0.1˚C. Our reconstruction suggests warmer waters contributed on average 0.08 ± 0.1 m and a peak contribution of 0.39 ± 0.1 m to global sea level.

The Eurasian Modern Pollen Database (EMPD) contains pollen counts and associated metadata for 8134 modern pollen samples from across the Eurasian region. The EMPD is part of, and complementary to, the European Pollen Database (EPD) which contains data on fossil pollen found in Late Quaternary sedimentary archives. The purpose of the EMPD is to provide calibration datasets and other data to support palaeoecological research on past climates and vegetation cover over the Quaternary period.

Annually laminated lake sediments (varves) record past climate change at seasonal resolution. The VARved sediments DAtabase (VARDA) is created to utilize the full potential of varves for climate reconstructions. VARDA offers free access to a compilation and synchronization of standardized climate-proxy data, with applications ranging from reconstructing regional patterns of past climate change to validating simulations of climate models. VARDA is freely accessible at https://varve.gfz-potsdam.de

Reconstructions try to extract a climate signal from paleo-observations. It is essential to understand their uncertainties. Similarly, comparing climate simulations and paleo-observations requires approaches to address their uncertainties. We describe a simple but flexible noise model for climate proxies for temperature on millennial timescales, which can assist these goals.

Evenly spaced carbon and oxygen stable isotope records were produced from central European stalagmites. To mitigate the potential bias of interpolation, the variance spectra were carefully evaluated. The derived data are ready to use with conventional uni- and multivariate statistics, which are usually not prepared to handle the general characteristic of sedimentary paleoclimate records derived from geological sequences unevenly sampled in time.

We created a database of 2134 marine sediment cores above 30° N in the North Pacific from 1951 to 2016 to facilitate paleoceanographic and paleoclimate research. This database allows for accessibility to sedimentary sequences, age models, and proxies produced in the North Pacific. We found community-wide shifts towards multiproxy investigation and increased age model generation. The database consolidates the research efforts of an entire community into an efficient tool for future investigations.

The ACER (Abrupt Climate Changes and Environmental Responses) global database includes 93 pollen records from the last glacial period (73–15 ka) plotted against a common chronology; 32 also provide charcoal records. The database allows for the reconstruction of the regional expression, vegetation and fire of past abrupt climate changes that are comparable to those expected in the 21st century. This work is a major contribution to understanding the processes behind rapid climate change.

We document our best available data compilation of published ice core records of the greenhouse gases CO2, CH4, and N2O and recent measurements on firn air and atmospheric samples covering the time window from 156 000 years BP to the beginning of the year 2016 CE. A smoothing spline method is applied to translate the discrete and irregularly spaced data points into continuous time series. The radiative forcing for each greenhouse gas is computed using well-established, simple formulations.

Short summary
Radiolarians found in marine sediments are used to reconstruct past Southern Ocean environments. This requires a comprehensive modern dataset. The Southern Ocean Radiolarian (SO-RAD) dataset includes radiolarian counts from sites in the Southern Ocean. It can be used for palaeoceanographic reconstructions or to study modern species diversity and abundance. We describe the data collection and include recommendations for users unfamiliar with procedures typically used by the radiolarian community.
