About Benjamin P. Weitzman

While completing his undergraduate in Marine Biology at UC Santa Cruz, Ben began working with captive sea otters with the Long Marine Laboratory, Marine Mammal Physiology Project, and later went on to work with the California Department of Fish & Wildlife on sea otter field research and necropsies, eventually specializing in sea otter capture techniques using rebreathers and beginning to work for the US Geological Survey Western Ecological Research Center and Alaska Scienter Center as a Wildlife Biologist, obtaining a Masters degree in Ecology & Evolutionary Biology from UC Santa Cruz and Ph.D. in Marine Biology from University Alaska Fairbanks along the way. Most recently, Ben spent two years working as an ecologist for NOAA's National Centers for Coastal Ocean Science in Homer, AK, before joining the US Fish & Wildlife Service's Sea Otter program for Marine Mammals Management in Anchorage, AK. Ben's research has orbited around sea otters, the invertebrate prey they consume, and the nearshore ecosystems they inhabit across their range in the North Pacific to understand how sea otters have influenced and are influenced by change in nearshore ecosystems. Ben's work has contributed to long-term monitoring efforts in the Aleutian Archipelago, Glacier Bay National Park, and he currently participates in the Gulf Watch Alaska nearshore program in the Gulf of Alaska (https://gulfwatchalaska.org/monitoring/nearshore-ecosystems-4/). Now working with Marine Mammals Management in Anchorage, AK, Ben brings his sea otter expertise to informing management and decision making, contributes to Stock Assessment Reports, leads sea otter survey and field research efforts, and serves as the local Field Dive Officer for the Sea Otter Dive Team.

Listen to Ben talk about his career path on this episode of My Life, Wildlife.
