- New research suggests that icebergs from the North American ice sheet once drifted past Florida when it began to melt 20,000 years ago. This research is supported by “massive scars” found along the continental shelf off Florida. Discovery News

Ocean Roundup: Fish Finding It Difficult to Adapt to Climate Change, Oceans Warmer Than Thought, and More

Spiny damselfish could take generations to adapt to climate change

- New research shows that fish aren’t quickly adapting to climate change, and it may take them several generations to do so. Researchers found that young spiny damselfish fish were no better than their parents at adapting to higher CO2 levels in seawater. The Guardian

- In a remarkable rescue, members of an orca pod helped save one of their own from fishing gear off New Zealand. Rescuers say the pod pushed the orca, who was carrying a 77-pound cray pot line, to the ocean’s surface to breath, and rescuers were then able to take over to free her from the gear. The Dodo

- 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

- According to a new report by the Assembly Select Committee on Sea Level Rise and the California Economy, California is “woefully unprepared” for sea level rise. The report projects that agriculture, tourism, and fishing industries will be most impacted by sea level rise. Think Progress

- It turns out that deep sea fish play a significant role in removing CO2 from surface water, according to a new study. The researchers found that deep sea fish are responsible for removing and storing more than one million tons of CO2 per year near Ireland and the United Kingdom. EurekAlert

West Antarctic Ice Sheet Collapse Calls for Revised Sea Level Rise Predictions

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.

Arctic Sea Ice at Second Lowest on Record

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

  • Scientists at the National Snow and Ice Data Center believe that Arctic sea ice reached its smallest extent for this year on September 9, at 4.33 million square kilometers. If this is the case, the only year since 1979 with less ice was 2007, but they note that if wind conditions change, the area covered by ice may still shrink.

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.
