Abstract Antarctic and Southern Ocean (ASO) marine ecosystems have been changing for at
least the last 30 years, including in response to increasing ocean temperatures and changes …

Humpback whales (Megaptera novaeangliae) were listed as endangered in 1970 under the
Endangered Species Conservation Act of 1969, the precursor to the Endangered Species …

High-latitude ecosystems are among the fastest warming on the planet. Polar species may
be sensitive to warming and ice loss, but data are scarce and evidence is conflicting,–. Here …

The Southern Ocean supports ecosystem services that are important on a global scale.
Climate change and human activities (tourism, fishing, and research) will affect both the …

Antarctic krill Euphausia superba (hereafter 'krill') occur in regions undergoing rapid
environmental change, particularly loss of winter sea ice. During recent years, harvesting of …

Although Antarctic sea ice is undergoing a slight increase in overall extent, major regional
changes are occurring in its spatio-temporal characteristics (most notably in sea ice …

Surveys of Euphausia superba often target localised shelves and ice edges where their
growth rates and predation losses are atypically high. Emphasis on these areas has led to …

The isolation of the Southern Ocean after the opening of Drake Passage some 23–25 million
years ago, the formation of the Antarctic Circumpolar Current, the subsequent cooling of the …

Antarctic krill, Euphausia superba, supports a valuable commercial fishery in the Southwest
Atlantic, which holds the highest krill densities and is warming rapidly. The krill catch is …

In shelf waters of the western Antarctic Peninsula (wAP), with abundant macro-and
micronutrients, water-column stability has been suggested as the main factor controlling …
