Spatial and Temporal Patterns in Ice Shelf Rift Mélange Across Antarctica Characterized Using Combined Satellite Observations
ADVANCING OUR UNDERSTANDING OF ICE SHELF PROCESSES II POSTER
cryosphere | 11 december 2023
Chancelor Roberts, Helen Amanda Fricker, Laurence ...
Nearly half of the mass loss from Antarctica is by iceberg calving from its ice shelves. Iceberg calving events are preceded by the growth of through-...

ADVANCING OUR UNDERSTANDING OF ICE SHELF PROCESSES II POSTER
cryosphere | 11 december 2023
Susheel Adusumilli, Helen Amanda Fricker, Laurence...
Half of the mass loss from Antarctica is via basal melting from its ice shelves, and melt rates are highest at the grounding zones of deep glaciers. I...
