Through the use of autonomous moored hydrophones, researchers record whale calls and determine the presence of different species in oceans throughout the world. An automatic detection software program, Ishmael, developed by CIMRS researcher, Dr. David Mellinger, is used to detect calls and thus create databases of whale calls around the world. This program has been used to detect calls of blue and minke whales from Atlantic Ocean hydrophones, right
and sperm whales from the Gulf of Alaska hydrophones, and (in collaboration with Scripps Institution of Oceanography) of dolphins off California.
