Fin whale ( Balaenoptera physalus) population identity in the western Mediterranean Sea
Abstract Archival bottom‐mounted audio recorders were deployed in nine different areas of the western Mediterranean Sea, Strait of Gibraltar, and adjacent North Atlantic waters during 2006–2009 to study fin whale ( Balaenoptera physalus ) seasonal presence and population structure. Analysis of 29,82...
