I'm Michalea King, a glaciologist studying how large outlet glaciers flow, calve, and drain ice into the surrounding ocean. Using a combination of satellite remote sensing, field observations, and modeling, my colleagues and I aim to better measure and understand how changes along the dynamic margins can impact ice sheet stability.
How calving at marine-terminating outlet glaciers drives transitions in subglacial hydrology. This thread pairs satellite remote sensing with ice-sheet modelling, including science questions enabled by NISAR (the NASA-ISRO Synthetic Aperture Radar mission). This research is supported by NASA Cryosphere.

This works adapts glacier velocity mapping techniques to better understand the spatiotemporal variability of ice mélange, the dense mix of icebergs and sea ice packed into glacial fjords, and how it couples to terminus stability and calving at the ice-ocean boundary.

Seasonal patterns in glacier terminus position and the hydraulic-potential fields that route water beneath the ice, built into reproducible tools for tracing meltwater pathways from bed and surface topography. This research is supported by NASA A.32: Studies with ICESat-2.
