Zooplankton-mediated carbon flux in the Southern Ocean: influence of community structure, metabolism and behaviour
Read more of: Zooplankton-mediated carbon flux in the Southern Ocean: influence of community structure, metabolism and behaviourThe biological carbon pump (BCP) exerts an important control on climate, exporting organic carbon from the ocean surface to interior. Zooplankton are a key component of the BCP and may […]

Metapopulation dynamics of roseate terns: Sources, sinks and implications for conservation management decisions
Read more of: Metapopulation dynamics of roseate terns: Sources, sinks and implications for conservation management decisionsHabitat management to restore or create breeding sites may allow metapopulations to increase in size and reduce the risk of demographic stochasticity or disasters causing metapopulation extinction. However, if newly […]

Factors influencing the habitat use of sympatric albatrosses from Macquarie Island, Australia
Read more of: Factors influencing the habitat use of sympatric albatrosses from Macquarie Island, AustraliaDifferences in habitat use of sympatric species are influenced by variability in functional morphology and life history trade-offs and are expected to shape species resilience to environmental change. To determine […]

The effects of enhanced sea ice export from the Ross Sea on recent cooling and freshening of the Southeast Pacific
Read more of: The effects of enhanced sea ice export from the Ross Sea on recent cooling and freshening of the Southeast PacificThe top 2000 m of the Southern Ocean has freshened and warmed over recent decades. However, the high-latitude (south of 50°S) southeast Pacific was observed to be cooler and fresher […]

Responses of sub-ice platelet layer thickening rate and frazil-ice concentration to variations in ice-shelf water supercooling in McMurdo Sound, Antarctica
Read more of: Responses of sub-ice platelet layer thickening rate and frazil-ice concentration to variations in ice-shelf water supercooling in McMurdo Sound, AntarcticaPersistent outflow of supercooled ice-shelf water (ISW) from beneath McMurdo Ice Shelf creates a rapidly growing sub-ice platelet layer (SIPL) with a unique crystallographic structure under the sea ice in […]

Scaling of size, shape and surface roughness in Antarctic krill swarms
Read more of: Scaling of size, shape and surface roughness in Antarctic krill swarmsAntarctic krill are obligate swarmers and the size and shape of the swarms they form can have a major influence on trophic interactions and biogeochemical fluxes. Parameterizing variability in size […]

Thurston Island (West Antarctica) between Gondwana subduction and continental separation: a multi-stage evolution revealed by apatite thermochronology
Read more of: Thurston Island (West Antarctica) between Gondwana subduction and continental separation: a multi-stage evolution revealed by apatite thermochronologyThe first low‐temperature thermochronological data from Thurston Island, West Antarctica, provide insights into the poorly constrained thermo‐tectonic evolution of the paleo‐Pacific margin of Gondwana since the Late Paleozoic. Here we […]

Expired drugs in the remote environment
Read more of: Expired drugs in the remote environmentThe British Antarctic Survey Medical Unit works in a very remote area of the world, with several Antarctic bases receiving only a single annual resupply of consumable goods. Pharmaceuticals supplied […]

Respiration rates and active carbon flux of mesopelagic fishes (Family Myctophidae) in the Scotia Sea, Southern Ocean
Read more of: Respiration rates and active carbon flux of mesopelagic fishes (Family Myctophidae) in the Scotia Sea, Southern OceanMesopelagic fish have recently been highlighted as an important, but poorly studied component of marine ecosystems, particularly regarding their role in the marine pelagic food webs and biogeochemical cycles. Myctophids […]

Molecular mechanisms underpinning transgenerational plasticity in the green sea urchin Psammechinus miliaris
Read more of: Molecular mechanisms underpinning transgenerational plasticity in the green sea urchin Psammechinus miliarisThe pre-conditioning of adult marine invertebrates to altered conditions, such as low pH, can significantly impact offspring outcomes, a process which is often referred to as transgenerational plasticity (TGP). This […]

Bright light phase shifts the human melatonin rhythm during the Antarctic winter
Read more of: Bright light phase shifts the human melatonin rhythm during the Antarctic winterIn most species daily and seasonal changes in the light-dark cycle are the most important synchronisers (zeitgebers) of daily and seasonal rhythms. In humans only bright light (2500 lux) appears […]
