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 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.
NOAA researchers set out this week on a two-week mission to fly over the Arctic to measure how much the ice has melted over the summer and gauge the speed of this fall’s refreezing of sea ice. This is the second year in a row scientists have flown above Arctic waters. Data gathered from both years is testing a hypothesis that increased summer heat stored in the newly sea-ice free areas of the Arctic Ocean lead to surface heat fluxes in autumn that are large enough to have impacts on atmospheric temperature, humidity, wind and cloud distributions.
NOAA and the U.S. Navy are teaming up with academic and other government scientists to design the next generation of powerful supercomputer models to predict weather, ocean conditions and regional climate change.
Four teams of scientists are beginning projects this month to rewrite computer models that will create faster, lower-cost, better integrated models. These new models will take advantage of new supercomputers that use more energy efficient/lower-cost processors such as those originally developed for the video gaming industry.
Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.
