Sedimentary records can illuminate relationships between the climate, topography, and glaciation of West Antarctica by revealing its Cenozoic topographic and paleoenvironmental history. Eocene fluvial drainage patterns have previously been inferred […]
Antarctic Bottom Water (AABW) is derived from dense water that sinks from the Antarctic continental shelf to the deep ocean. The sinking of AABW is balanced by a return flow […]
Dotson Ice Shelf (DIS) is located in the Amundsen Sea sector of Antarctica, an area of rapid glacial mass loss due to ocean-driven basal melting. Here, warm Circumpolar Deep Water […]
Societal adaptation to rising sea levels requires robust projections of the Antarctic Ice Sheet’s retreat, particularly due to ocean-driven basal melting of its fringing ice shelves. Recent advances in ocean […]
We document the glacial system model (GSM), which is designed for large ensemble ice sheet modelling in glacial cycle contexts. A distinguishing feature is the extent to which it addresses […]
Measurements of pre-industrial conditions are of paramount importance for understanding historical climate change. The Southern Ocean and Antarctic continent are some of the least polluted environments on planet Earth. Alkylamines […]
Primary producers shape terrestrial biodiversity, but most research has focused on vascular plants, while the role of cryptogams (mosses, lichens and algae) remains under-explored. Cryptogams dominate Antarctic vegetation and support […]
Seymour (Marambio) Island, Antarctica has one of the most expanded onshore Cretaceous–Paleogene sedimentary successions in the world. The deposition of the López de Bertodano Formation (~70–65.6 Ma) covered a time of […]
Bryophytes play an important role as habitats for many organisms, especially invertebrates, however, few studies have focused on understanding the cryptic ecosystems associated with them. The use of molecular tools […]
Far from being frozen and sterile environments, glaciers are biogeochemical reactors and regulators. In this Review, we discuss the hydrology and biogeochemistry of glacierized environments and their impact on downstream […]
We present outcomes from our 17th horizon scan of issues potentially impacting global biodiversity conservation in the next decade. Issues are novel, or represent a significant step-change in impact, and […]
Radiocarbon-dated fossils indicate woolly mammoths were extirpated from mainland Beringia around 13 000 years ago. However, environmental DNA in permafrost suggests small “cryptic“ populations survived into the Holocene. Resolving this discrepancy […]
