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 […]
This mooring timeseries compilation contains temperature, salinity, current velocity measured from a wide range of marine instrument in the Southern Ocean (90°S-60°S) since 1975. It provides with an opportunity to […]
The four cross cutting themes (storylines) of OCEAN:ICE are: The ‘Antarctic Bottom Water’ theme, led by Povl Abrahamsen (UKRI-BAS). The ‘Deep Uncertainty in Freshwater Fluxes (DUFF)’ theme, led […]
Mooring deployments. Partner in charge of delivery of the milestone: UKRI-BAS.
Two oceanographic moorings were recovered from Royal Research Ship Sir David Attenborough on 24-25 February 2025. Data have been downloaded from instruments and will be backed up on internal BAS […]
The Transpolar Drift (TPD) plays a crucial role in regulating Arctic climate and ecosystems by transporting fresh water and key substances, such as terrestrial nutrients and pollutants, from the Siberian […]
Antarctica is a very cold, isolated continent surrounded by frozen seas, yet these extreme environmental conditions have not restricted life and diversity in the sea. The marine environment is seasonally […]
Measurements from a robotic underwater vehicle reveal the impacts of meltwater from the giant iceberg A-68A on the properties of the surrounding Southern Ocean. In addition to increasing surface stratification […]
Antarctica has been subject to direct human activity for a little over 200 years. In recent decades, the combination of sharp increases in human activity and regional climate change, particularly […]
Globally, seabirds remove a prey biomass equivalent to commercial fishery landings, suggesting likely competition for resources that will vary spatially and seasonally. Using extensive aerial surveys combined with species-specific energetic […]
