Oceanic mesoscale structures, such as eddies, play a fundamental role in ocean circulation, ocean biogeochemical cycles and plankton ecology. They cause lateral and vertical advection, as well as interact with […]
Climate change is impacting marine ecosystems worldwide, presenting a significant threat to biodiversity. In the Southern Ocean, organisms are facing increasing challenges due to warming, ocean acidification, reduced sea-ice cover, […]
Polar ecosystems are on the forefront of climate change, yet large parts of our polar seas remain unexplored. This affects our ability to detect change in these regions and hampers […]
This paper presents new marine geophysical data and radiocarbon dated sediment cores to reconstruct the maximum extent of the Northeast Greenland Ice Stream (NEGIS) during the last glaciation and the […]
Based on a regional 3D seismic data set and a small high‐resolution 3D seismic data set (~40 km 2 ) we have mapped a buried glacially eroded trough on the […]
Pine Island Bay (PIB), situated in the Amundsen Sea, is renowned for its retreating ice shelves and highly variable sea ice. While brine rejection from sea ice formation and glacial […]
The polar regions are biologically productive and play a critical role in regional and global biogeochemical cycling. A key nutrient is dissolved silicon, required for the growth of siliceous phytoplankton, […]
Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high post-larval krill recruitment the following spring, suggesting that sea […]
Detrital zircon U-Pb and Lu-Hf data from the youngest (upper Permian) sedimentary succession of the Falkland/Malvinas Islands is used to constrain depositional age, provenance and palaeogeography, and test the Natal […]
Genomic adaptation and introgression can occur during the speciation process, enabling species to diverge in their frequencies of adaptive alleles or acquire new alleles that may promote adaptation to environmental […]
Although fisheries bycatch is the greatest threat to many migratory marine megafauna, it remains unclear how population exposure to bycatch varies across the global range of threatened species. Such assessments […]
Geomagnetically induced current (GIC) measurements made at two 3 phase, 3 limb transformers, operating in the Halfway Bush substation in Dunedin, New Zealand have been analyzed during the May 2024 […]
