The NAMMCO Scientific Committee held its first planning meeting for the Trans North Atlantic Sightings Surveys (TNASS) in Reykjavik, Iceland on 19 March 2006.


The TNASS project will estimate the abundance of cetacean populations in the Northern North Atlantic from survey data collected during summer 2007. It will become part of a long-term series of international North Atlantic Sightings Surveys (NASS) that have been conducted in 1987, 1989, 1995 and 2001. The TNASS will cover areas to the west of Greenland and the northeastern coast of Canada that have not been covered in earlier surveys, providing a full trans-Atlantic coverage for the first time. Canada, Greenland, Iceland, the Faroe Islands, Norway and the Russian Federation will participate in the survey, which will also be co-ordinated with surveys conducted in other areas of the North Atlantic. TNASS will also be an International Polar Year project.
