Your Captain - John M. Maniscalco, Ph.D., Capt.
Dr. John Maniscalco first came to Alaska with the U.S. Coast Guard in 1985 and has operated a wide variety of vessels along Alaska's coast since then. After leaving the Coast Guard, he entered academia earning a Bachelor of Science in Biology, a Master of Science in Fisheries, and a Ph.D. in Marine Biology from the University of Alaska. John's research studies have focused on seabird and marine mammal ecology in Prince William Sound, southeastern Alaska, and along the northern Gulf of Alaska coast. He has authored more than 20 articles in high profile scientific journals and has appeared on multiple episodes of Ocean Mysteries with Jeff Corwin highlighting his research activities (Season 2; Episodes 3, 5, 8). John has been working as a research scientist at the Alaska SeaLife Center in Seward, Alaska since the summer of 2000 where he continues studying the behavior and population dynamics of Steller sea lions and nesting seabirds. John has been a licensed captain in Alaska since 1992 and has been operating vessels in the Kenai Fjords region since 1999. He knows the birds inhabiting the Kenai coast and is the best person on the water to help you find the species you are looking for!
