GPS tracks and animal recordings (both catches and sightings) from July to September 2015, documented by two hunters from Savissivik who participated in the Piniariarneq study. The difference between the glacier fronts as of August 1st 2015 (in blue), and the glacier fronts charted on the topographic map (in black), demonstrates that the glacier in the bottom of Illaarsussuaq (Sidebriksfjord) has retracted more than 7 km, opening up the area in which the narwhals were hunted during the open water season of 2015. The narwhals did not return Illaarsussuaq in the summer of 2016
