Distinct layers of firn were observed to the south, where the ice cap ends in a small cliff of 19 m in height.
Most of the island is covered by an ice cap that rises to 35 m above sea level, as determined by airborne laser scanning.
All of them are located along the crest of the ice cap.
They noted a strongly bisected coastline, with inlets reaching towards the ice cap, and numerous meltwater lakes, often without apparent external discharge.
There is widespread evidence from terrestrial samples of ice and snow, including ice cap cores that contain organic compounds.
Their results confirmed from space the 2001 airborne measurements of an ice cap up to 35 m high, and an island of 2 km extent.
During this visit it became clear that there was only one island, not a group of islets, and that the ice cap was higher than previously estimated.
In addition to the official flag hoisting and the geodetic measurements, three samples of gravel and one sample with moss were collected north of the ice cap.
