Advancing the classification of supraglacial lake winter behaviours on the Greenland Ice Sheet using Sentinel-1 time series analysis

Characterizing Ice Phenology Variability of Small Lakes in the Cascade Mountain Range Using Daily Ice Presence Probabilities from Satellite Remote Sensing

Lake ice is a reliable indicator of climate variability and change. This research investigates annual and spatial variations in lake ice phenology of small lakes (<2 km2) in the Cascade Mountain Range (U.S.A.) using high-temporal frequency remote-sensing data and a probabilistic model. Data from the Harmonized Landsat-...

Drivers, detection and impacts of rain-on-snow events on Banks Island, Canadian Arctic Archipelago: insights from remote sensing and Inuit Knowledge

Current warming trends in polar regions have increased the frequency of rain-on-snow (ROS), which impacts snow microstructure and leads to the formation of ice crusts. We draw on Inuit Knowledge (IQ), alongside passive microwave satellite imagery and local measurements, to investigate both the drivers and the consequen...

Retrieval of Supraglacial Lake Water Surface Elevation and Depth Over the Greenland Ice Sheet Using SWOT Observations

Accurate quantification of supraglacial lake water surface elevation (WSE) and depth is essential for understanding surface mass balance processes of the Greenland Ice Sheet. However, optical remote sensing in polar regions is severely limited by cloud cover and floating ice, hindering all-weather, high-accuracy lake d...

Spatial heterogeneity in post-fire permafrost evolution as revealed by satellite radar observations

Temporal evolution of the Petermann Ice Shelf estuary constrained by satellite remote sensing observations

Supraglacial rivers may reduce ice-shelf instability by draining meltwater from the ice-shelf surface, limiting loading-induced stresses from ponded meltwater. However, if a supraglacial river incises to below sea level at the ice-shelf front, forming an estuary, this effect may be negated. Water flow reversal in the e...
