Glacier icefields cover a significant part of Alaska and they effect the state’s resource based economy. Power generation, tourism activities and fish productivity are all influence by the behavior of glaciers. Glacier change from icefield to ocean affects Alaska’s future. Shad O’Neel, a researcher with the U.S. Geological Survey has coauthored a paper that begins […]
Ocean acidification risk assessment for ...
Alaska is dependent on a healthy marine environment to preserve its commercial fishing industry and the traditional subsistence harvest of seafood. Researchers are anticipating rapid changes in temperature and ocean acidification of the waters that support Alaska’s fisheries. A study has recently been published that promotes the use of an ocean acidification risk assessment for […]
2014 Valdez Silver Salmon Run Failure Ex...
Causes of the Valdez Silver salmon run failure that occurred in 2014 are being examined by the local fish hatchery. Hatchery management with the Valdez Fisheries Development Association (VFDA), a private non-profit salmon hatchery in Prince William Sound, have been investigating the weak return of Coho or Silver salmon to the region that occurred last […]
First known freshwater springs found ben...
Researchers working with the Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) have found what are believed to be the first documented freshwater springs found at the base of a tidewater glacier in Alaska. This investigation was conducted by the Prince William Sound Science Center in support of ongoing council research focused on Columbia Glacier. […]
Alaskan Fisheries are being threatened f...
Due to increases in the carbon dioxide (CO2) caused by global human development, Alaskan Fisheries are being threatened from ocean acidification. There are at least two highly productive crab fisheries located in state that could be harmed by the uptake of atmospheric CO2 into marine waters. A study published in Progress in Oceanography addresses this […]
Rate and Scale of Arctic Ocean Acidifica...
Researchers have found the rate and scale of Arctic Ocean acidification is unparalleled in recent history. Some 20 percent of the Canadian Basin has become more acidic in a short period of time. Swiftly melting sea ice is being seen as the primary cause of this increase in acidification. Seawater absorbs around 25 percent of […]
