1. Blinded by the light – Seabird collision events in South Georgia

   Light-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. […]

2. Using seabird and whale distribution models to estimate spatial consumption of krill to inform fishery management

   Ecosystem 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 […]

3. Radar characterization of ice crystal orientation fabric and anisotropic viscosity within an Antarctic ice stream

   We 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 […]

4. Two techniques for determining F-region ion velocities at meso-scales: Differences and impacts on Joule heating

   We 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 […]

5. Record low Antarctic sea ice cover in February 2022

   On 25 February 2022 Antarctic sea ice extent (SIE) dropped to a satellite-era record low level of 1.92 × 106 km2, 0.92 × 106 km2 below the long-term mean. The […]

7. Study of an Arctic blowing snow-induced bromine explosion event in Ny-Ålesund, Svalbard

   Bromine explosion events (BEEs) are important processes that influence the atmospheric oxidation capacity, especially in the polar troposphere during spring. Although sea ice surface is thought to be a significant […]

8. Voluntary actions by the Antarctic krill fishing industry help reduce potential negative impacts on land-based marine predators during breeding, highlighting the need for CCAMLR action

   The Commission for the Conservation of Antarctic Marine Living Resources is responsible for management of the Antarctic marine ecosystem, including its living resources. The Commission has yet to implement precautionary […]

9. Winters are changing: Snow effects on Arctic and alpine tundra ecosystems

   Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions, and moisture availability during winter. It also affects the growing season’s start […]

10. Bacterial colonisation: From airborne dispersal to integration within the soil community

    The deposition of airborne microorganisms into new ecosystems is the first stage of colonisation. However, how and under what circumstances deposited microorganisms might successfully colonise a new environment is still […]

11. Climate‐driven substitution of foundation species causes breakdown of a facilitation cascade with potential implications for higher trophic levels

    1. Climate change can alter ecological communities both directly, by driving shifts in species distributions and abundances, and indirectly by influencing the strength and direction of species interactions. Within benthic […]

12. Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica

    Subglacial meltwater drainage can enhance localized melting along grounding zones and beneath the ice shelves of marine-terminating glaciers. Efforts to constrain the evolution of subglacial hydrology and the resulting influence […]
