Internal clocks determine the ups and downs of Antarctic krill

Antarctic krill not only react to external environmental influences such as light or food. They also use their internal clocks to adapt to the extreme conditions of the polar environment.

Expedition braves Antarctic for data on melting glacier

Antarctic expeditioners have returned to Australia with intel about potentially new species and a rapidly melting glacier, plus...

Increasing high latitude coexistence of Antarctic salps and krill under projected climate change

In the Southern Ocean, Antarctic krill and salps, both macroplankton species, have overlapping distributions but play contrasting roles in the food web. However, their population trajectories and interactions remain uncertain. In this study, we developed a novel 3D model to predict their chang...

Internal Clocks Determine the Ups and Downs of Antarctic Krill

9.05.2025 - The behavior of Antarctic krill not only reacts to external environmental influences such as light or food. It also uses its internal clock to adapt to the extreme conditions of the polar environment.

First all-Canadian Antarctic expedition draws underwater maps using GNSS technology

Canadian scientists recently led their first Antarctic research expedition, using Montreal-made Arrow Gold+ GNSS technology for precise location data in remote and challenging conditions. The mission, which departed in early March 2025 aboard HMCS Margaret Brooke, included experts from multiple Canadian universities and government agencies. Researchers conducted water, sediment, air, and sea-ice sampling to study climate change, glacial retreat …
