The Arctic around Svalbard has experienced among the most intense, sustained warming anywhere on Earth for multiple decades, which is projected to continue. Increasing air and sea temperatures are not […]
Highlights • The Antarctic Peninsula, part of British Antarctic Territory, is warming rapidly, up to two times the global mean rate of 0.27°C per decade. • Substantial and irreparable environmental […]
Breeding in sympatry may increase competition among closely related species, especially when these species are colonial central-place foragers. Niche partitioning, for example through segregation in space, time, habitat or diet, […]
Understanding the connectivity between spawning and nursery grounds of Antarctic krill Euphausia superba is essential for elucidating population dynamics and informing ecosystem-based management of krill. This study employed a regional […]
The Antarctic Peninsula is warming rapidly, with more frequent extreme temperature and precipitation events, reduced sea ice, glacier retreat, ice shelf collapse, and ecological shifts. Here, we review its behaviour […]
The Arctic Ocean has been changing rapidly in a warming climate. To monitor these changes, it is useful to classify the Arctic Ocean into water masses-bodies of water with similar […]
Walruses (Odobenus rosmarus) are experiencing rapid habitat change, concomitant with dramatic sea ice declines in the Arctic. Reduction in sea ice also creates the potential for reduced benthic production and […]
Precise synchronization of paleoclimate records is essential for inferring the dynamics and past evolution of the climate system. For the last glacial period, the time scales of ice cores from […]
The Gulf Stream is important for the climate system through its transport and air-sea exchange of heat. What is less well accepted is the role of the Gulf Stream in […]
It is currently debated whether Earth system models (ESMs) can reproduce observation-based long-term changes in global and regional deoxygenation rates. Both models and observations include uncertainties, which must be considered […]
Seismic hazard estimates rely on interevent time distributions between earthquakes of a given magnitude. In the Himalaya, recurrence intervals are usually modeled as cyclic or quasiperiodic, whereas globally, they range […]
The polar ice sheets, their surrounding land fringes and oceans (68 × 106 km2; 13% of Earth’s surface) are hot spots for carbon cycle perturbation under future climate change due […]
