Oodaaq

Oodaaq or Oodap Qeqertaa was a bank of gravel and silt northeast of Greenland. During the first modern survey and mapping of northern Greenland in 1978, which had a side goal to position both Cape Morris Jesup and Kaffeklubben Island, the small c. 50 × 100 m Oodaaq Island was sighted by geodetic survey assistant Uffe Petersen to the north of Kaffeklubben Island during Doppler satellite measurements at the north tip of Kaffeklubben Island. The gravel bank, which later turned out to be a debris-covered iceberg, was measured in connection with the first modern geodetic survey of northernmost Greenland by the Danish Geodetic Institute and added to the national topographic map of Greenland as it was assumed to be an island. A few years later Oodaaq disappeared, and it turned out to have been an iceberg.
