- A new study found that tiny crabs of the species Planes major, which were thought to hitch rides on the back of sea turtle shells and remain there for life with a mate, may not be as monogamous as once thought. New research shows that males may actually hop off turtles in search of a mate in what researchers are calling “risky behavior.” Smithsonian Science

- The Chesapeake Bay experienced their eighth-largest dead zone this summer since record keeping began in the 1980s, according to Maryland’s Department of Natural Resources. Officials say this signals larger issues with Bay health, and that much more work is needed to reduce nutrient input and pollution. The Washington Post

A section of the West Antarctic Ice Sheet has declined to a point that’s irreversible, two groups of NASA scientists reported last week. As NASA’s narration explains below, six glaciers in particular are rapidly melting into the Amundsen Sea, and there are no barriers like mountains or hills to halt this retreat. Scientists point to climate change and warmer ocean temperatures as causes.

The latest sea ice data are out, and they aren't pretty. Here’s the latest:

The sea ice data in particular are drawing a lot of attention because sea ice maintenance affects weather patterns around the globe, melting ice contributes to warmer oceans and rising sea levels, and unusual ice patterns can wreak havoc on the lives of native humans and animals, particularly polar bears, which can drown, and walruses, which can starve.
