Encounter rates of cetaceans in the Mediterranean Sea and contiguous Atlantic area
A series of visual-acoustic surveys were carried out in the Mediterranean Sea between 2003 and 2007 from RV 'Song of the Whale'. Almost 21,000 km of trackline were surveyed between the longitudes of 14 degrees W and 36 degrees E with an emphasis on regions with low survey effort. Survey tr...
