Parameter sensitivity analysis of dynamic ice sheet models-Numerical computations [PDF]

open access: yesarXiv, 2019
The friction coefficient and the base topography of a stationary and a dynamic ice sheet are perturbed in two models for the ice: the full Stokes equations and the shallow shelf approximation. The sensitivity to the perturbations of the velocity and the height at the surface is quantified by solving the adjoint equations of the stress and the height ...

Air–sea–ice interactions in Isfjorden, Svalbard: An atmospheric perspective

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Due to its location and complex topography, atmospheric conditions in the Isfjorden region in central Svalbard are highly variable in space and time. Using new high‐resolution atmospheric reanalysis data, we show that near‐surface wind channeling and cold air advection strongly impact the winter heat extraction from the fjord, comparable to the effect ...

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

open access: yesQuarterly 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

open access: yesGeophysical 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 ...

Stabilized Extracellular Vesicle Formulations for Inhalable Dry Powder Development

open access: yesSmall, 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.

Nanoparticle Therapeutics in Clinical Perspective: Classification, Marketed Products, and Regulatory Landscape

open access: yesSmall, EarlyView.
This review presents a detailed overview of clinically approved nanoparticle therapeutics, classifying them by type and discussing their unique advantages in drug delivery. It highlights regulatory challenges across global markets and emphasizes the need for adaptive approval pathways.

RIS-Vis: A Novel Visualization Platform for Seismic, Geodetic, and Weather Data Relevant to Antarctic Cryosphere Science [PDF]

open access: yesarXiv
Antarctic ice shelves play a vital role in preserving the physical conditions of the Antarctic cryosphere and the Southern Ocean, and beyond. By serving as a buttressing force, ice shelves prevent sea-level rise by restraining the flow of continental ice and glaciers to the sea.
