Warming ocean may bring major changes for U.S. northeast fish species

NOAA Fisheries and NOAA Research scientists collaborate on vulnerability assessment

NOAA scientists have released the first multispecies assessment of just how vulnerable U.S. marine fish and invertebrate species are to the effects of climate change. The study examined 82 species that occur off the Northeastern U.S., where ocean warming is occurring rapidly.  Researchers found that most species evaluated will be affected, and that some are likely to be more resilient to changing ocean conditions than others. The study appears in PLOS ONE, an online scholarly science journal. 

Warming waters a major factor in Gulf of Maine cod collapse

New study shows how warming complicates fisheries management

For centuries, cod was the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks in the gulf are on the verge of collapse, hovering at 3-4 percent of sustainable levels. Even setting tighter limits on fishing has failed to slow this rapid decline. Now a new

 report in Science concludes that rapid warming of Gulf of Maine waters— warming in the last decade faster than in 99 percent of the global ocean —has reduced the capacity of cod to rebound from overfishing, leading to collapse.

In Alaska’s Bering Strait and Arctic regions, there are dozens of Alaskan Native tribes, many of whom depend on the marine environment for food, as they have in some cases for thousands of years.  In this world more foreign to most Americans than many other countries (and bigger than many too) works exactly one NOAA Oceanic & Atmospheric Research Sea Grant extension agent: Gay Sheffield.

New study finds Alaskans familiar with ocean acidification, not aware...

New research published in Marine Policy from the first Alaska-focused study on public understanding and awareness of ocean acidification risk shows that Alaskans are three times more aware of ocean acidification than Americans in general.  However, Alaskans have difficulty seeing ocean acidification as an immediate risk, and the direct risks to Alaska’s fisheries are still not well understood. The research, “Gauging perceptions of ocean acidification in Alaska,” can be read online.
