Variability in the freshwater balance of northern Marguerite Bay, Antarctic Peninsula: results from δ18O
Read more of: Variability in the freshwater balance of northern Marguerite Bay, Antarctic Peninsula: results from δ18OWe investigate the seasonal variability in freshwater inputs to the Marguerite Bay region (Western Antarctic Peninsula) using a time series of oxygen isotopes in seawater from samples collected in the […]

On the interannual variability of ocean temperatures around South Georgia, Southern Ocean: forcing by El Niño/Southern Oscillation and the Southern Annular Mode
Read more of: On the interannual variability of ocean temperatures around South Georgia, Southern Ocean: forcing by El Niño/Southern Oscillation and the Southern Annular ModeThe ocean around South Georgia, in the southwest Atlantic sector of the Southern Ocean, is highly productive, with large stocks of Antarctic krill supporting extensive colonies of marine and land-based […]

Eddy heat flux in the Southern Ocean: response to variable wind forcing
Read more of: Eddy heat flux in the Southern Ocean: response to variable wind forcingWe assess the role of time-dependent eddy variability in the Antarctic Circumpolar Current (ACC) in influencing warming of the Southern Ocean. For this, we use an eddy-resolving quasigeostrophic model of […]

Monitoring Drake Passage with elephant seals: frontal structures and snapshots of transport
Read more of: Monitoring Drake Passage with elephant seals: frontal structures and snapshots of transportCTD-Satellite Relay Data Loggers (CTD-SRDLs), each recording conductivity, temperature and pressure, were attached to Southern elephant seals (Mirounga leonina) on the island of South Georgia. During the animals’ migration the […]

Unlocking the time capsule of historic aerial photography to measure changes in Antarctic Peninsula glaciers
Read more of: Unlocking the time capsule of historic aerial photography to measure changes in Antarctic Peninsula glaciersRecent studies have reported widespread retreat and acceleration of glaciers on the Antarctic Peninsula, attributed to regional warming. The loss of ice is a contributor to sea-level rise, but its […]

Distribution and ecology of Chaenocephalus aceratus (Channichthyidae) around South Georgia and Shag Rocks (Southern Ocean)
Read more of: Distribution and ecology of Chaenocephalus aceratus (Channichthyidae) around South Georgia and Shag Rocks (Southern Ocean)Chaenocephalus aceratus (Family Channicthyidae) is one of the dominant species of demersal fish living on the South Georgia shelf where it is caught in low numbers as by-catch in the […]

Risks posed to the Antarctic marine environment by acoustic instruments: a structured analysis
Read more of: Risks posed to the Antarctic marine environment by acoustic instruments: a structured analysisThe risks posed by a range of acoustic scientific instruments were assessed by the construction of matrices of scale and likelihood. We recognized six levels of impact ranging from none […]

Modelling gene networks at different organisational levels
Read more of: Modelling gene networks at different organisational levelsApproaches to modelling gene regulation networks can be categorized, according to increasing detail, as network parts lists, network topology models, network control logic models, or dynamic models. We discuss the […]

Which cyanobacterial genotypes are observed in microbial mats of Antarctic lakes?
Read more of: Which cyanobacterial genotypes are observed in microbial mats of Antarctic lakes?Cyanobacteria are the dominant phototrophs in Antarctic biota where they form conspicuous microbial mats at the bottom of lakes and ponds. In the frame of the OSTC project LAQUAN (EV/12/1B), […]
