Mapping Surface Flow Velocity of Glaciers at Regional Scale Using a Multiple Sensors Approach
Remote Sensing, 2019 We explore and compare the capabilities and limitations of different optical sensors (Sentinel-2/ESA, Landsat 7/8/USGS, Ven μ s/CNES-ISA, Pléiades/AirbusD&S and Planet Labs images) for mapping the surface speeds of mountain glaciers on ...

Impact of Salinity on Ground Ice Distribution Across an Arctic Coastal Polygonal Tundra Environment
Permafrost and Periglacial Processes, EarlyView.ABSTRACT The heterogeneous distribution of ground ice in the Arctic is a key driver of uneven ground subsidence as permafrost thaws, significantly impacting infrastructure and surface/subsurface hydrology. These topographic and hydrological changes contribute to major uncertainties in energy and carbon fluxes and storage in a warming Arctic. This study

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Rising sea levels and changing marine dynamics are increasing the inundation of previously terrestrial permafrost, accelerating thaw and altering microbial carbon cycling. On the Arctic Coastal Plain of Alaska, permafrost features like drained lake basins (DLBs) and uplands (ULs), offer distinct redox conditions and formation histories that ...

Episodic Subglacial Drainage Cascades Below the Northeast Greenland Ice Stream
Geophysical Research Letters, 2023 Subglacial hydrology can exert an important control on ice flow by affecting friction at the ice‐bedrock interface. Here, we report on a series of subglacial drainage events along the Northeast Greenland Ice Stream (NEGIS), initiating as far inland as ...

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 ...

Boreas, EarlyView.Morphometric values of streamlined subglacial bedforms provide valuable information about the relative speed, direction, and maturity of past ice streams. This paper presents a new tool that utilizes a machine learning approach to automatically identify glacially derived streamlined features.
