New paper: “Wintertime Fjord-Shelf Interaction and Ice Sheet Melting in Southeast Greenland”

A computer simulation of the ocean around Greenland was used to study the movement of water in and out of a large fjord. This is important because warm water that gets into the fjord may come into contact with the Greenland Ice Sheet and cause it to melt. The simulation indicates that a significant amount of warm water comes into contact with the ice during the winter. This was previously difficult to measure because of the difficulties in taking direct measurements of the water during the Greenland winter.

This work was based on Dr Neil Fraser’s PhD, but the model was forced using realistic winter wind conditions rather than idealised wind.  This was the first time (for me) that using Paraview to analyse model data in 4D has led or contributed to a publication.
