Southern Sea Otter Research and Population Status
Once abundant in California, southern sea otters were nearly hunted to extinction during the fur trade. The USGS and numerous research partners monitor the population status of sea otters and conduct a variety of tagging and tracking studies that investigate areas of behavioral ecology including movement patterns, foraging ecology, reproduction, and survival. We also design studies to examine the role sea otters play in nearshore ecosystems, especially in the face of environmental change.

Joe Tomoleoni
Biologist and Regional Dive Safety Officer @U. S. Geological Survey, Western Ecological Research Center
Joe is a biologist and regional dive safety officer with the U. S. Geological Survey’s Western Ecological Research Center. After obtaining his master’s degree in Fisheries Biology from the University of Miami, Joe relocated to the West Coast where he has been studying sea otter ecology since 2008. His fieldwork has taken him from Southern California and the Channel Islands, to the most remote islands in the Aleutian Archipelago, and many places in between, monitoring regional sea otter populations, studying their behavior, and surveying habitat and prey resources.
