Thawing subsea permafrost in the East Siberian Arctic Seas releases methane, a potent greenhouse gas. Using molecular fossils in sediments, we traced aerobic methane oxidation as a proxy of enhanced methane cycling across the Laptev Sea, including in regions once thought low in emissions. This approach captures long-term patterns of methane cycling over years-decades , overcoming limits of short-term seawater measurements and highlights the importance of the Laptev Sea in Arctic methane cycling.

This paper reviews how the Alfred Wegener Institute studies changes in the ocean and the polar ice regions under climate warming. We bring together results from field observations, laboratory work, and computer models to show how melting ice and changing seas affect global climate and sea level. By combining many approaches, we identify key advances, remaining gaps, and future priorities. Integrating these methods improves our ability to project future climate change and guide decision-making.

We refined the age-depth models of marine sediment cores from the western Laptev Sea shelf using authigenic 10Be/9Be ratios. Pre-depositional 14C ages of terrigenous biomarkers in the cores revealed distinct transport pathways. n-C28:0 fatty acids exhibited varied sources/transport mechanisms between periods strongly influenced by coastal erosion and river discharge, whereas n-alkanes suggested aged permafrost as the dominant source.

We investigated the occurrence and transport of microplastics in air and coastal waters around the Maldives using air and seawater sampling and particle identification. Microplastics occurred in both environments, but their size distributions and composition differed markedly. Airborne concentrations were more closely associated with polluted air transported from South Asia than with local ocean emissions, indicating that regional atmospheric transport delivers microplastics to remote islands.

Seasonal monsoon winds transport aerosol particles across the equatorial Indian Ocean. Measurements in the Maldives show that the northeast monsoon carries polluted air from South and Southeast Asia, whereas the southwest monsoon brings cleaner marine air from the southern Indian Ocean. These observations improve our understanding of long-range pollution transport and help improve climate and air-quality models.

Today’s sea-ice-covered Arctic Ocean hosts only one species of calcifying planktonic foraminifera, unlike warmer oceans with diverse communities. Fossils show that other species once inhabited the Arctic, but their identities and environmental significance remain uncertain. Using detailed microscopy and hundreds of shell measurements, we resolve these fossil species and establish a new taxonomic framework providing the foundation for improved reconstructions of Quaternary Arctic climate history.

Methane is a powerful greenhouse gas, but its sources remain uncertain in many regions. The isotope fingerprints of methane are diagnostic of its sources, yet their source end-members are poorly constrained for South Asia. Here we determined the methane isotope signal for major sources in South Asia and found these to differ from global averages. Improved regional-specific isotope source fingerprints will help to improve top-down assessments of methane budgets and climate mitigation strategies.

South Asia has the world's highest loadings of sulfate, scattering sunlight, altering clouds and masking greenhouse warming, yet there are large uncertainties regarding the relative contributions of natural and anthropogenic sources to the receptor atmosphere. Here we use δ34S isotopes to distinguish natural versus anthropogenic sulfate sources, revealing strong seasonal contrasts and quantifying the dominance of anthropogenic contributions.

Our study examined how sea ice in the Beaufort Sea has changed over the past 13 000 years to better understand today's rapid losses. By analyzing chemical tracers preserved in seafloor sediments, we found that the Early Holocene was largely ice-free, with warmer waters and lower salinity. Seasonal ice began forming about 7000 years ago and expanded as the climate cooled. These long-term patterns show that continued warming could return the region to mostly ice-free conditions.

Understanding how ice sheets have changed in the past can allow us to make better predictions for the future. By running a state-of-the-art model of Ryder Glacier, North Greenland, over the past 12 000 years we find that both a warming atmosphere and the ocean play a key role in the evolution of the glacier. Our conclusions stress that accurately quantifying the ice sheet’s interactions with the ocean is required to predict future changes and reliable sea level rise estimates.

The South Asian Pollution Experiment 2018 used access to three strategically located receptor observatories. Observational constraints revealed opposing trends in the mass absorption cross sections of black carbon (BC MAC) and brown carbon (BrC MAC) during long-range transport. Models estimating the climate effects of BC aerosols may have underestimated the ambient BC MAC over distant receptor areas, leading to discrepancies in aerosol absorption predicted by observation-constrained models.

Shape and surface texture of silt-sized grains are measured to connect marine sediment records with subglacial water flow. We find that grain shape alteration is greatest in glaciers where high-energy drainage events and abundant melting of surface ice are inferred and that the surfaces of silt-sized sediments preserve evidence of glacial transport. Our results suggest grain shape and texture may reveal whether glaciers previously experienced temperate conditions with more abundant meltwater.

The Greenland ice sheet is highly sensitive to global warming and a major contributor to sea level rise. In Northeast Greenland, ice–ocean–tectonic interactions are readily observable today, but geological records that illuminate long-term trends are lacking. NorthGreen aims to promote scientific drilling proposals to resolve key scientific questions on past changes in the Northeast Greenland margin that further affected the broader Earth system.

This study provides ground-observational evidence that supports earlier suggestions that savanna fires are the main emitters and modulators of carbon monoxide gas in Africa. Using isotope-based techniques, the study has shown that about two-thirds of this gas is emitted from savanna fires, while for urban areas, in this case Nairobi, primary sources approach 100 %. The latter has implications for air quality policy, suggesting primary emissions such as traffic should be targeted.

For assessing the consequences of human-induced climate change for the marine realm, it is necessary to not only look at gradual changes but also at abrupt changes of environmental conditions. We summarise abrupt changes in ocean warming, acidification, and oxygen concentration as the key environmental factors for ecosystems. Taking these abrupt changes into account requires greenhouse gas emissions to be reduced to a larger extent than previously thought to limit respective damage.

We investigate how topographical sills suppress basal glacier melt in Greenlandic fjords. The basal melt drives an exchange flow over the sill, but there is an upper flow limit set by the Atlantic Water features outside the fjord. If this limit is reached, the flow enters a new regime where the melt is suppressed and its sensitivity to the Atlantic Water temperature is reduced.

We report aspartic and glutamic acid racemization analyses on Neogloboquadrina pachyderma and Cibicidoides wuellerstorfi from the Arctic Ocean (AO). The rates of racemization in the species are compared. Calibrating the rate of racemization in C. wuellerstorfi for the past 400 ka allows the estimation of sample ages from the central AO. Estimated ages are older than existing age assignments (as previously observed for N. pachyderma), confirming that differences are not due to taxonomic effects.

Short summary
Oxygen isotopes are used to date marine sediments via similar large-scale ocean patterns over glacial cycles. However, the Arctic Ocean exhibits a different isotope pattern, creating uncertainty in the timing of past Arctic climate change. We find that the Arctic Ocean experienced large local oxygen isotope changes over glacial cycles. We attribute this to a breakdown of stratification during ice ages that allowed for a unique low isotope value to characterize the ice age Arctic Ocean.

This research contributes to efforts solving research questions related to the history of ice sheet decay in the Northern Hemisphere. The East Siberian continental margin sediments provide ideal material for identifying the mineralogical signature of ice sheet derived material. Heavy mineral analysis from marine glacial sediments from the De Long Trough and Lomonosov Ridge was used in interpreting the activity of the East Siberian Ice Sheet in the Arctic region.

Short summary
Sea ice is an important regulator of the Arctic climate systems. Records of sea ice past instrumental records are necessary to understand how sea ice is altered during past periods of abrupt climate change, and what consequences such changes have on the polar climates. Here, we reconstructed the sea ice cover of the East Siberian Arctic and found that the sea ice extent likely was linked to protecting/eroding permafrost coastlines during the last deglaciation.
Sea ice is an important regulator of the Arctic climate systems. Records of sea ice past...
