It is my sad task to inform the marine mammal community that Dr. Ken Marten passed in his sleep in Hawaii on July 5, 2010. Ken was an experienced animal cognition researcher and former NMFS observer on purse-seine tuna boats. After witnessing first hand the "dolphin holocaust" aboard the tuna boats, Ken devoted himself to advancing scientific understanding--and public awareness--of the unique dolphin mind. Ken worked at UC Santa Cruz Long Marine Lab with Dr. Ken Norris and many others, before moving to Hawaii where he ran a research lab for many years, exploring dolphin self-awareness and studying Hawaiian spinner dolphin populations for the nonprofit organization Earthtrust. Ken's intellectual curiosity, unique personality, readiness to laugh, and passionate commitment to conservation of marine mammals will be remembered by anyone who worked with him. Please help spread the news to people who knew Ken, but who may not be on Marmam's list. A memorial will be held in Hawaii by the family sometime during the week of July 19.
