In Southeast Alaska, sea otters have made a critical comeback after their populations were decimated during the fur trade. With their numbers growing, how are these charismatic critters impacting the ecosystem? Learn about the critical role this species plays in maintaining the health of seagrass habitat and what Earthwatch researchers and volunteers have uncovered so far.

YOUR SUPPORT MATTERS
Earthwatch depends on donations—above and beyond what we raise from volunteers who participate on our expeditions—in order to deliver our global conservation mission. In fact, volunteer contributions provide only half of the total resources Earthwatch needs to sustain over 40 field research expeditions, a wide variety of educational programs, corporate sustainability trainings, and more each year.
