Data sets

Continental scale, high order, high spatial resolution, ice sheet modeling using the Ice Sheet System Model (ISSM) (https://issm.jpl.nasa.gov/) E. Larour, H. Seroussi, M. Morlighem, and E. Rignot https://doi.org/10.1029/2011JF002140

Short summary

We use an ice sheet model to determine what influenced the Greenland Ice Sheet to retreat across a portion of southwestern Greenland during the Holocene (about the last 12 000 years). Our simulations, constrained by observations from geologic markers, show that atmospheric warming and ice melt primarily caused the ice sheet to retreat rapidly across this domain. We find, however, that iceberg calving at the interface where the ice meets the ocean significantly influenced ice mass change.
