To better understand the ecological consequences of ocean warming on marine ecosystems, experimental manipulation of ecologically relevant parameters is essential. Here, we employed short-term (3 months) in situ heated settlement […]
Atmospheric rivers (ARs) play a major role in transporting heat and moisture into the Arctic, yet their thermodynamic structure and regional impacts remain poorly understood. Here, we adopt a combined […]
Late Holocene glacial dynamics in Maritime Antarctica are relatively poorly understood due to limited data availability. Here, we present a reconstruction of neoglacial ice advance on Signy Island (South Orkney […]
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for […]
The West Antarctic Ice Sheet (WAIS) has undergone rapid change over the satellite era, characterized by significant thinning, grounding-line retreat, and mass loss. More than a third of the ice […]
Accurate estimates of vegetation cover underpin ecological monitoring and conservation, yet lichens, the dominant primary producers across the coldest biomes remain poorly represented. Recent satellite-derived products provide Antarctic-wide estimates of […]
Species distribution models using animal tracking data to predict foraging habitat suitability can inform dynamic ocean management techniques that respond to changing environmental conditions. Such models require accurate transferability in […]
The stability of the West Antarctic Ice Sheet (WAIS) remains a major uncertainty in sea-level projections, and geologic records provide important constraints on its past behavior. We present 40Ar/39Ar ages […]
Antarctica’s remote wilderness is increasingly impacted by human activities such as tourism, scientific research, and historical and contemporary exploitation of marine resources. Despite regulatory measures, these activities continue introducing pollutants, […]
Background With over 10,000 recognized species, birds constitute one of the most diverse and widely distributed vertebrate groups. Although avian genomics has advanced rapidly over the past decade, substantial gaps […]
Ecosystem engineering is an important factor influencing species establishment in novel environments. Here we tested how shell middens created by kelp gulls (Larus dominicanus) affect the growth of candidate non-native […]
During the 94/95 field season seismic measurements of the ice- and water-column thickness were made at 15 km (average) intervals along a 2300 km traverse. This zig-zag traverse covered the […]
