In the North Atlantic, euphausiids (krill) form a major link between primary production and predators including commercially exploited fish. This basin is warming very rapidly, with species expected to shift…1 December, 2021 by Huw Griffiths, Katrin Linse
Peracarid data were collected in the Southern Ocean and South Atlantic Ocean. Sampling was performed during nine different expeditions on board of RRS James Clark Ross and RV Polarstern, using…1 December, 2021 by Johnathan Ross, Nigel Meredith, Richard Horne, Sarah Glauert
The interactions between electromagnetic ion cyclotron (EMIC) waves and relativistic electrons are influential in diffusing radiation belt electrons into the loss code from which the electrons are lost into the…1 December, 2021 by Dave Munday
Declining atmospheric CO2 concentrations are considered the primary driver for the Cenozoic Greenhouse-Icehouse transition, ~34 million years ago. A role for tectonically opening Southern Ocean gateways, initiating the onset of…Read more on Gateway-driven weakening of ocean gyres leads to Southern Ocean cooling

We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate (1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or…

According to central place foraging theory, animals will only increase the distance of their foraging trips if more distant prey patches offer better foraging opportunities. Thus, theory predicts that breeding…1 December, 2021 by Dave Munday
The transfer of momentum between the atmosphere and ocean is dependent upon the velocity difference between the seawater and overlying air. This is commonly known as relative wind, or ocean…Read more on Relative vs. absolute wind stress in a circumpolar model of the Southern Ocean.

Foraging site selection and site fidelity can have implications for many ecological processes. The degree of site fidelity differs greatly not just between species but also within populations. Some of…1 December, 2021 by Markus Frey
Anthropogenically driven changes in the cryosphere (mainly climate warming, but also land-use changes and increasing industrial and transportation activities) are changing how the cryosphere interacts with the atmosphere, which is,…1 December, 2021 by Liz Thomas
The West Antarctic climate has witnessed large changes during the second half of the twentieth century including a strong and widespread continental warming, important regional changes in sea-ice extent and…
