Oodaaq Ø and other short-lived islets north of Greenland

  • Ole Bennike (a1) and Jeff Shea (a2)

Abstract

In 1978, a small island was discovered north of Kaffeklubben Ø, until then considered the most northern island on Earth. This island was named Oodaaq Ø. It was visited again in 1979, and in 1980 it was seen from Kaffeklubben Ø by members of the Sirius sledge patrol. Sirius searched for Oodaaq Ø again from 1981 to 1984 but did not find it. During the period from 1996 to 2008, the region was visited regularly and a number of new islets were discovered: the 1996 ATOW Island, KMS Island, 2001 RTOW Island, 83-42 Island, Stray Dog West Island and the 2008 Island. The islets are composed of gravel. We believe the area with islets is shallow, being a continuation of a coastal plain to the south. We suggest that the sea floor in the area is irregular and that the islets form by floes of sea ice that bulldoze material from the sea floor up above sea level. In some cases, perhaps all, the islets disappear when sea ice floes bulldoze sediment back below sea level. Alternatively, the so-called islets are just accumulations of gravel on sea ice.
