Since September 2003, John Pearse (University of California, Santa Cruz, Emeritus Professor) has been counting the number of sea otters he observes off Hopkins Marine Station's West Beach. Using binoculars, counts are made from the window of the Pearse residence positioned directly across the street from the beach. Time is presented on a 24-hour clock. Time of day for the count is haphazardly chosen. Counts extend from September 2003 through July 2009.
