Tabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, […]
Emperor penguins are highly reliant on stable fast ice for successful breeding, and some studies project possible quasi-extinction for most colonies by 2100 due to future sea-ice loss. To better […]
Beringia’s extensive late Quaternary deposits of yedoma silt provide rich floristic and faunal records. Sampling of frozen yedoma exposures typically uses multiple baydzherakhs (residual silt heaps developed as conical thermokarst […]
Ocean freshening due to increased precipitation and ice melting in a warming world poses a significant threat to marine calcifiers. The reduced availability of calcification substrates and an undersaturated calcium […]
The ice shelves in the Amundsen Sea are being melted rapidly by warm Circumpolar Deep Water(CDW), causing sea‐level rise. Ice‐shelf melt variability is controlled by the speed of a shelf‐break […]
1. The timing of breeding is an important aspect of any species’ realised niche, reflecting adaptations to synchronise with food supplies, dilute predation, avoid competition and exploit seasonal fluctuations in […]
Phenotypic responses to climate affect individual fitness, but the extent to which this translates into effects on population dynamics remains poorly understood. We assemble 213 time series on phenotypes and […]
The response of the Antarctic ice sheet to climate change and its contribution to sea level under different emission scenarios are subject to large uncertainties. A key uncertainty is the […]
In recent decades, high demand from stakeholders and policymakers has intensified research efforts toward operational seasonal forecasts. This is particularly relevant when it comes to El Niño-Southern Oscillation (ENSO), the […]
Ocean warming affects ectotherm physiological and phenological processes, potentially creating mismatches between early life stages and their prey. Seasonal spawning cohorts are thought to provide flexibility in responding to environmental […]
The Global Biodiversity Framework underpins global policies driving marine protection and conservation. Meeting the targets of these policies requires an understanding of how marine ecosystems respond to anthropogenic pressures such […]
A compilation of in situ temperature and salinity profiles south of 45° S is assembled, drawing from multiple data centers and sensor sources. This database is then used to create […]
