The Transarctic Acoustic Propagation (TAP) experiment bas been carried out in April 1994. During the 5 days of the experiment, thirty-one CW and twelve broadband acoustic signals lasting 1 hour were transmitted at 19.6 Hz from ice camp TURPAN as it drifted 300 km north of Spitsbergen, over 2600 km to the ice camp SIMI in the Beaufort Sea, and 900 km to the ice camp NARWHAL in the Lincoln Sea. The main goal of the experiment was to explore the feasibility of long-range long-term acoustic transmissions in the Arctic Ocean for monitoring climatic changes in the ocean temperature and the ice cover.
