SMRU Small Cetacean Abundance in the North Sea (SCANS), 1994
Listed in NASA Earthdata CMR
The Small Cetacean Abundance in the North Sea (SCANS) project was initiated in 1993.
Description
Dedicated line transect shipboard surveys were conducted between 27 June and 26 July 1994. Transects covered 20,000km2 in an area of 890,000km2.
The survey area included the region specified in the Agreement on Small Cetaceans Of the Baltic And North Seas (ASCOBANS) (excluding most of the Baltic Sea proper) and the Celtic Sea. The shipboard methodology involved simultaneous survey from two independent observation platforms, one of which searched farther ahead of the vessel than the other. There were two observation platforms on each of the nine vessels participating in the SCANS project.

Three species dominate the dataset; the harbour porpoise (Phocoena phocoena), white-beaked dolphin (Lagenorhynchus albirostris) and minke whale (Balaenoptera acutorostrata). The dataset is a point file containing information on all sighting events from each platform on each vessel during survey effort. The effort file contains the start and end positions for each leg of survey effort for each vessel and associated parameters.
The data have been extracted from the Joint Cetacean Database.
