Helgoland Habitat

The UWL was used in the waters of the North and Baltic Seas and, in 1975, on Jeffreys Ledge, in the Gulf of Maine along the coast of New England in the United States.

[4][5] The laboratory was lifted by the floating crane "Magnus 4" in April 1970 and placed on the mole of the South Helgoland harbour.

On September 25, 1975, German aquanaut Joachim Wendler died of an decompression sickness while returning to the surface of the Gulf of Maine from Helgoland.

He was participating in a checkout mission for the First International Saturation Study of Herring and Hydroacoustics (FISSHH) project.

[7][8][9] At the end of the 1970s the laboratory was decommissioned, and in the summer of 1998 it was donated to the German Oceanographic Museum by the GKSS Research Centre, Geesthacht.
