1. Chapter 5 – Ice in the sea

   Sea ice plays a key role for climate and is important as habitat and for human activities and economies. Observations show and models indicate that climate and sea-ice regimes are […]

2. The gut microbiota of three avian species living in sympatry

   Background Evolutionary divergence and genetic variation are often linked to differences in microbial community structure and diversity. While environmental factors and diet heavily influence gut microbial communities, host species contributions […]

3. Ship collision risk threatens whales across the world’s oceans

   After the near-complete cessation of commercial whaling, ship collisions have emerged as a primary threat to large whales, but knowledge of collision risk is lacking across most of the world’s […]

4. Photophysiology of the first reported bleached crustose coralline alga, Clathromorphum sp. (Hapalidiales, Rhodophyta), from Antarctica

   During a 2019 Chilean Antarctic Scientific Expedition (ECA 55) studying crustose coralline algae (CCA) diversity on the Antarctic Peninsula, bleaching of these algae was observed for the first time in […]

5. Geological evolution and construction of a glacierized active intra-oceanic arc volcano: Visokoi Island (South Sandwich Islands)

   Visokoi is a small volcanic island in the remote South Sandwich Islands and is unique in being dominated by the basaltic andesite products of highly explosive eruptions. Here, its geology […]

6. High historical movement rates of Antarctic blue whales on Southern Ocean feeding grounds estimated from Discovery mark data

   Little is known about Antarctic blue whale (Balaenoptera musculus intermedia) movement and migration. In many baleen whales, distinct populations arose due to inherited fidelity to migration routes between breeding and […]

7. Perspectives on using peat records to reconstruct past atmospheric Hg levels

   Anthropogenic mercury (Hg) emissions to the atmosphere have increased the concentration of this potent neurotoxin in terrestrial and aquatic ecosystems. The magnitude of regional variation in atmospheric Hg pollution levels […]

8. Downscaling precipitation over High-mountain Asia using multi-fidelity Gaussian processes: improved estimates from ERA5

   The rivers of High-mountain Asia provide freshwater to around 1.9 billion people. However, precipitation, the main driver of river flow, is still poorly understood due to limited in situ measurements […]

9. Contrasting copepod community composition in two Greenland fjords with different glacier types

   Greenland’s fjord ecosystems are strongly influenced by meltwater discharge from glaciers. Marine-terminating glaciers can significantly enhance primary production during the melt season (compared to land-terminating glaciers), but their impact on […]

10. Extremely low biodiversity Arctic intertidal habitats as sentinels for environmental change

    The Arctic is undergoing dramatic changes, including an unprecedented decline in sea ice. Previous studies have shown the severe structuring impact of sea ice scour upon polar intertidal communities. A […]

11. Dated radar-stratigraphy between Dome A and South Pole, East Antarctica: old ice potential and ice sheet history

    An array of information about the Antarctic ice sheet can be extracted from ice-sheet internal architecture imaged by airborne ice-penetrating radar surveys. We identify, trace and date three key internal […]

12. First discovery of Antarctic amber [Short note]

    Here, we report the first discovery of Antarctic fossil resin (commonly referred to as amber) within a ~5 cm-thick lignite layer, which constitutes the top part of a ~3 m-long […]
