Mortality trends in northern sea otters (Enhydra lutris kenyoni) collected from the coast of Washington and Oregon during 2002—2015: Data During 2002−2015 we examined the causes of mortality in beachcast northern sea otters (Enhydra lutris kenyoni) collected from the coasts of Washington and Oregon states. A total of 333 moribund or dead sea otters were reported through opportunistic observations and 93 otter carcasses were collected for necropsy. Retrieved carcasses received a full diagnostic evaluation to determine cause of death when carcass condition permitted. Otter stranding reports were received from the entire Washington coast and northern Oregon coast, but carcasses located near areas populated by humans were most often in suitable condition for cause of death determination. Data in this release include basic demographic information on the...

Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Kenai Fjords National Park between 2002 and 2016. Sea otters are a keystone predator, well known for structuring the nearshore marine ecosystem through their consumption of invertebrate prey. The dataset consists of 3 comma delimited files exported from Microsoft Excel. The data consists of 1. Strip transect counts, 2. Intensive Search Unit (ISU) counts, and 3. Transect coordinates. For each aerial survey, a pilot flew an airplane at an altitude of 91m over pre-determined transects while an...
