Original provider: Caroline Weir Dataset credits: Caroline Weir, Ketos Ecology Karen Stockin, Sea Watch Foundation Abstract: Spatial and temporal trends in the distribution of the harbor porpoise <i>Phocoena phocoena</i>, white-beaked dolphin <i>Lagenorhynchus albirostris</i>, and minke whale <i>Balaenoptera acutorostrata</i> were assessed at a coastal North Sea study area in Aberdeenshire, Scotland. Between March 1999 and October 2001, cetacean data were collected using both land- and vessel-based survey methods. A total of 174 sightings of these three cetacean species was recorded during approximately 330 h of combined survey effort (228 h land-based and 102 h vessel-based).
