Inbreeding depression, the loss of offspring fitness due to consanguineous mating, is generally detrimental for individual performance and population viability. We investigated inbreeding effects in a declining population of Antarctic […]
Understanding past variability in Antarctic sea ice is of critical importance to determine how it regulates global climate processes, biogeochemistry, and Southern Ocean marine ecosystems. Records of changes in Holocene […]
Aerosols play a critical role in the Arctic’s radiative balance, influencing solar radiation and cloud formation. Limited observations in the central Arctic leave gaps in understanding aerosol dynamics year-round, affecting […]
Significant changes have occurred during the last few decades across the North Atlantic climate system, including in the atmosphere, ocean, and cryosphere. These large-scale changes play a vital role in […]
Low-concentration insoluble microparticles that are preserved in ice cores offer valuable information for reconstructing past environmental changes. However, their low concentrations and limited sample availability present challenges for extraction and […]
We present a 1000 km transect of phase-sensitive radar measurements of ice thickness, basal reflection strength, basal melting, and ice-column deformation across the Ross Ice Shelf (RIS). Measurements were gathered […]
We present a genome assembly from an individual female Electrona antarctica (the Antarctic lanternfish; Chordata; Actinopterigii; Myctophiformes; Myctophidae). The genome sequence has a total length of 1,427.40 megabases. Most of […]
Executive Summary: Change to Thwaites Glacier in West Antarctica, sometimes referred to as the “Doomsday Glacier”, over the coming decades and centuries will have profound implications for global sea-level rise […]
Coastal freshening in the Southern Ocean is expected to increase under projected climate scenarios. As a major environmental stressor, prolonged reduced salinity could pose a significant challenge to Antarctica’s endemic […]
Arctic regions are among the fastest warming areas of the planet. Increasing average temperatures over the last five decades have deepened the thawing of the upper-most layer of permafrost across […]
Background: The west Antarctic Peninsula (WAP) is a region of rapid environmental changes, with regional differences in climate warming along the north–south axis of the peninsula. Along the WAP, Palmer […]
