Study of an Arctic blowing snow-induced bromine explosion event in Ny-Ålesund, Svalbard
Read more of: Study of an Arctic blowing snow-induced bromine explosion event in Ny-Ålesund, SvalbardBromine 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 […]

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
Read more of: 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 actionThe 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 […]

Winters are changing: Snow effects on Arctic and alpine tundra ecosystems
Read more of: Winters are changing: Snow effects on Arctic and alpine tundra ecosystemsSnow 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 […]

Bacterial colonisation: From airborne dispersal to integration within the soil community
Read more of: Bacterial colonisation: From airborne dispersal to integration within the soil communityThe 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 […]

Climate‐driven substitution of foundation species causes breakdown of a facilitation cascade with potential implications for higher trophic levels
Read more of: Climate‐driven substitution of foundation species causes breakdown of a facilitation cascade with potential implications for higher trophic levels1. 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 […]

Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica
Read more of: Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, AntarcticaSubglacial 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 […]

Tidal Modulation of a Lateral Shear Margin: Priestley Glacier, Antarctica
Read more of: Tidal Modulation of a Lateral Shear Margin: Priestley Glacier, AntarcticaWe 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 […]

Whales from space dataset, an annotated satellite image dataset of whales for training machine learning models
Read more of: Whales from space dataset, an annotated satellite image dataset of whales for training machine learning modelsMonitoring 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 […]

Large Methane Emission Fluxes Observed from Tropical Wetlands in Zambia
Read more of: Large Methane Emission Fluxes Observed from Tropical Wetlands in ZambiaMethane (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 […]

Early‐to-late winter 20th century North Atlantic multidecadal atmospheric variability in observations, CMIP5 and CMIP6
Read more of: Early‐to-late winter 20th century North Atlantic multidecadal atmospheric variability in observations, CMIP5 and CMIP6The 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 […]
