1. 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 […]

2. 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 […]

3. Tidal Modulation of a Lateral Shear Margin: Priestley Glacier, Antarctica

   We use high resolution, ground-based observations of ice displacement to investigate ice deformation across the floating left-lateral shear margin of Priestley Glacier, Terra Nova Bay, Antarctica. Bare ice conditions allow […]

4. South Sandwich Islands – An understudied isolated Southern Ocean archipelago: Editorial

   The South Sandwich Islands are an isolated, oceanic, volcanically formed archipelago in the Atlantic sector of the Southern Ocean. The complex bathymetry, coupled with the location in the marginal sea-ice […]

5. Whales from space dataset, an annotated satellite image dataset of whales for training machine learning models

   Monitoring whales in remote areas is important for their conservation; however, using traditional survey platforms (boat and plane) in such regions is logistically difficult. The use of very high-resolution satellite […]

6. Large Methane Emission Fluxes Observed from Tropical Wetlands in Zambia

   Methane (CH4) is a potent greenhouse gas with a warming potential 84 times that of carbon dioxide (CO2) over a 20-year period. Atmospheric CH4 concentrations have been rising since the […]

7. Early‐to-late winter 20th century North Atlantic multidecadal atmospheric variability in observations, CMIP5 and CMIP6

   The strong multi-decadal variability in North Atlantic (NA) winter atmospheric circulation is poorly understood and appears too weak in climate models. Recent research has shown peak atmospheric multi-decadal variability over […]

8. UV-B-induced DNA damage and repair pathways in polar Pseudogymnoascus sp. from the Arctic and Antarctic regions and their effects on growth, pigmentation, and coniodiogenesis

   Solar radiation regulates most biological activities on Earth. Prolonged exposure to solar UV radiation can cause deleterious effects by inducing two major types of DNA damage, namely cyclobutane pyrimidine dimers […]

9. Exceptional middle latitude electron precipitation detected by balloon observations: Implications for atmospheric composition

   Energetic particle precipitation leads to ionization in the Earth’s atmosphere, initiating the formation of active chemical species which destroy ozone and have the potential to impact atmospheric composition and dynamics […]

10. Active Precipitation of Radiation Belt Electrons using Rocket Exhaust Driven Amplification (REDA) of Man‐Made Whistlers

    Ground-based VLF transmitters located around the world generate signals that leak through the bottom side of the ionosphere in the form of whistler mode waves. Wave and particle measurements on […]

11. Antarctic Climate Change and the Environment: A Decadal Synopsis and Recommendations for Action

    This report provides concise compiled synopses of current understanding, explicit recommendations for actions to address change, and recommendations for additional research. In most cases, the research recommendations are drawn from […]

12. Diversity, distribution and ecology of fungal communities present in Antarctic lake sediments uncovered by DNA metabarcoding

    We assessed fungal diversity in sediments obtained from four lakes in the South Shetland Islands and James Ross Island, Antarctica, using DNA metabarcoding. We detected 218 amplicon sequence variants (ASVs) […]
