Thermokarst Lagoons: Distribution, Classification and Dynamics in Permafrost‐to‐Marine Transitions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The transition of permafrost landscapes to marine environments, driven by climate change, plays a crucial role in the global carbon cycle. Thermokarst lagoons, formed along permafrost coasts when thermokarst lakes get connected to the sea, are key features in this transition.

Sensitivity of near‐surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configuration

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Marine winds near coastal Antarctica are important for sea‐ice variability and ocean circulation. We test the sensitivity of simulated winds to varying uncertain aspects of the atmospheric model configuration. Winds (each configuration a coloured solid line in the figure) are sensitive to model physics, and notably we find that wind stress over a ...

Novel Record of Intermittent Grounding of the Venable Ice Shelf Since 1935 From Operation IceBridge Airborne‐Gravity‐Derived Bathymetry and Landsat Imagery

Geophysical Research Letters
Future projections and past reconstructions of Antarctic Ice Sheet stability and sea‐level rise depend on knowledge of continental shelf bathymetry, which controls water circulation under floating ice and interactions between the ice shelf and seafloor ...

Contrasting impacts of two mesoscale cyclones on the South Shetland Islands' glaciers, northern Antarctic Peninsula

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Stabilized Extracellular Vesicle Formulations for Inhalable Dry Powder Development

Small, EarlyView.
Extracellular vesicles (EVs) hold promise for chronic obstructive pulmonary disease (COPD) treatment but face challenges with storage and delivery. This study demonstrates the stabilization of lung fibroblast‐derived EVs using inulin, enabling freeze‐drying and spray‐drying.
