Abstract:
Estimated Lagrangian thinning rates from phase-sensitive radar (pRES) measurements at 41 locations at 79°N Glacier (Nioghalvfjerdsfjorden Glacier) in northeast Greenland between 2017 and 2018 (see link in "Further details"). Thinning rates are based on pRES-derived ice thicknesses in 2017 and 2018. Off-nadir thinning rates estimates are minimum values and are based on the first basal return.
