Towards incorporation of blue carbon in Falkland Islands marine spatial planning: a multi-tiered approach
Read more of: Towards incorporation of blue carbon in Falkland Islands marine spatial planning: a multi-tiered approachEcosystem-based conservation that includes carbon sinks, alongside a linked carbon credit system, as part of a nature-based solution to combating climate change, could help reduce greenhouse gas levels and therefore […]

Analysis of migrating and non-migrating tides of the Extended Unified Model in the mesosphere and lower thermosphere
Read more of: Analysis of migrating and non-migrating tides of the Extended Unified Model in the mesosphere and lower thermosphereAtmospheric tides play a key role in coupling the lower, middle, and upper atmosphere/ionosphere. The tides reach large amplitudes in the mesosphere and lower thermosphere (MLT), where they can have […]

The International Bathymetric Chart of the Southern Ocean Version 2
Read more of: The International Bathymetric Chart of the Southern Ocean Version 2The Southern Ocean surrounding Antarctica is a region that is key to a range of climatic and oceanographic processes with worldwide effects, and is characterised by high biological productivity and […]

Relative sea-level data preclude major late Holocene ice-mass change in Pine Island Bay
Read more of: Relative sea-level data preclude major late Holocene ice-mass change in Pine Island BayThe rapidly retreating Thwaites and Pine Island glaciers together dominate present-day ice loss from the West Antarctic Ice Sheet and are implicated in runaway deglaciation scenarios. Knowledge of whether these […]

New 10Be ages improve Holocene ice sheet thinning history near the grounding line of Pope Glacier, Antarctica
Read more of: New 10Be ages improve Holocene ice sheet thinning history near the grounding line of Pope Glacier, AntarcticaEvidence for the timing and pace of past grounding line retreat of the Thwaites Glacier system in the Amundsen Sea embayment (ASE) of Antarctica provides constraints for models that are […]

Stable silicon isotopes uncover a mineralogical control on the benthic silicon cycle in the Arctic Barents Sea
Read more of: Stable silicon isotopes uncover a mineralogical control on the benthic silicon cycle in the Arctic Barents SeaBiogeochemical cycling of silicon (Si) in the Barents Sea is under considerable pressure from physical and chemical changes, including dramatic warming and sea ice retreat, together with a decline in […]

Blinded by the light – Seabird collision events in South Georgia
Read more of: Blinded by the light – Seabird collision events in South GeorgiaLight-induced bird strikes on vessels occur frequently in association with areas of high seabird density, often resulting in bird mortalities. These incidents are poorly understood and likely under-reported by vessels. […]

Using seabird and whale distribution models to estimate spatial consumption of krill to inform fishery management
Read more of: Using seabird and whale distribution models to estimate spatial consumption of krill to inform fishery managementEcosystem dynamics at the northwest Antarctic Peninsula are driven by interactions between physical and biological processes. For example, baleen whale populations are recovering from commercial harvesting against the backdrop of […]

Radar characterization of ice crystal orientation fabric and anisotropic viscosity within an Antarctic ice stream
Read more of: Radar characterization of ice crystal orientation fabric and anisotropic viscosity within an Antarctic ice streamWe use polarimetric radar sounding to investigate ice crystal orientation fabric, and its impact on ice viscosity, within the near-surface of Rutford Ice Stream, West Antarctica. The technique retrieves lateral […]

Two techniques for determining F-region ion velocities at meso-scales: Differences and impacts on Joule heating
Read more of: Two techniques for determining F-region ion velocities at meso-scales: Differences and impacts on Joule heatingWe have investigated the difference between two standard techniques for deriving the ionospheric ion velocity using data taken with the EISCAT incoherent scatter radar between 1987 and 2007. For large-scale […]
