The ObSERVE Aerial project was carried out by an international consortium led by University College Cork with international partners IMARES, Alnilam and Aerosotravia.  It involved a team of trained observers flying over the sea in a specially equipped aeroplane along an extensive set of survey lines, in order to record the occurrence, distribution and numbers of whales, dolphins, porpoises and seabirds.  Other species of interest such as sharks and sea turtles were also seen and recorded.
