The charismatic otter, a member of the weasel family, is found on every continent except Australia and Antarctica. Most are small, with short ears and noses, elongated bodies, long tails, and soft, dense fur.
There are 13 species in total, ranging from the small-clawed otter to the giant otter. Though most live in freshwater rivers, lakes, and wetlands, the sea otter and the smaller marine otter are found in the Pacific Ocean.
In this episode we are entertained by whales, eagles, sea otters and spectacular views of the surrounding mountains. We start to wrap up our time in Prince William Sound and begin to position ourselves for our ocean passage south.
Prince William Sound is a sound of the Gulf of Alaska on the south coast of the U.S. state of Alaska. It is located on the east side of the Kenai Peninsula. Its largest port is Valdez, at the southern terminus of the Trans-Alaska Pipeline System.
Staff Writer Kelly Servick joins host Sarah Crespi to talk about the ins and outs of coronavirus contact tracing apps—what they do, how they work, and how to calculate whether they are crushing the curve. Edward Gregr, a postdoctoral fellow at the Institute for Resources, Environment, and Sustainability at the University of British Columbia, Vancouver, talks with Sarah about the controversial reintroduction of sea otters to the Northern Pacific Ocean—their home for centuries, before the fur trade nearly wiped out the apex predator in the late 1800s. Gregr brings a unique cost-benefit perspective to his analysis, and finds many trade-offs with economic implications for fisheries For example, sea otters eat shellfish like urchins and crabs, depressing the shellfishing industry; but their diet encourages the growth of kelp forests, which in turn provide a habitat for economically important finfish, like salmon and rockfish.
