Ocean acidification (OA) is the result of anthropogenic increases in atmospheric carbon dioxide that is later absorbed by the ocean. NOAA. The extent to which ocean acidification is currently affecting Alaska fisheries, and how it will affect fisheries in the future, are both important issues that we know relatively little about. Every day, 22 million tons of carbon dioxide from factories, cars, power plants and other human sources are absorbed by the world's oceans. A new study shows, for the first time, that ocean acidification is driving changes in waters vital to Alaska's commercial fisheries and traditional subsistence way of life. Ocean acidification is a threat to food security, economies, and culture because of its potential impacts on marine ecosystem services. At a Glance Scientists in Alaska have been studying the effects of ocean acidification on crabs. Arctic sea ice extent in September 2012 was the lowest in the satellite record (since 1979). A consequence of increasing CO 2 in the ocean is that it becomes harder for carbonate to mineralize.

But about a quarter of … Red and blue king crab ( Paralithodes camtschaticus and P. platypus) are both commercially important species in Alaska waters known to be sensitive to ocean acidification, or the reduction of pH in the ocean caused by human-released CO2. At risk are commercial and recreational fishing, tourism, and coral reefs. Ocean acidification results from an increased concentration of hydrogen ions and a reduction in carbonate ions due to the absorption of increased amounts of CO 2.

The impact of ocean acidification on corals is one of these dangers. The impacts of ocean acidification are uneven: southern Alaska faces the greater risk, due to its dependence on susceptible species for nutrition and income, the forecasted rapid change in chemical conditions and, as a rural area, its low job diversity, employment, and education levels, as well as its high food costs. In addition, deep oceanic waters are depleted in carbonate due to respiration resulting in a saturation depth below which calcium carbonate dissolves. 22 tons CO 2 every day. RB 15-04 Gulf of Alaska Ocean Acidification Survey 2015. Clams, mussels, crabs, corals, and other sea life rely on carbonate ions to grow their shells and thrive. Alaska’s coastal waters are some of the most commercially valuable and productive ecosystems on the planet. Ocean acidification threatens to cause billions of dollars in damage to the U.S. economy, harming everything from crabs in Alaska to coral reefs in Florida and the Caribbean, NOAA researchers said in a new draft research plan for ocean acidification. have created “ocean acidification hotspots” where changes are occurring at even faster rates. Alaska’s coastal waters are particularly vulnerable to ocean acidification because cold water can absorb more carbon dioxide, and unique ocean circulation patterns bring naturally acidic deep ocean waters to the surface. Project Description. Senator Lisa Murkowski (R-AK) recently introduced the Coastal Communities Ocean Acidification Act of 2017 to identify and assess communities, including island communities, low-population rural communities, and subsistence communities, that are most dependent on … As the oceans absorb more carbon dioxide from the air, the … If this work was prepared by an officer or employee of the United States government as part of that person's official duties it is considered a U.S. Government Work.

Alaska is expected to experience ocean acidification faster than any other United States coastal waters, primarily due to its colder water which absorbs more carbon dioxide than warmer waters. A new scientific model and associated web tool will help scientists, resource managers, fishermen and decision-makers understand ocean acidification in the Gulf of Alaska. A new study led by PMEL's Dr. Jeremy Mathis, published online July 29 in Progress in Oceanography, shows that many of Alaska's economically valuable marine fisheries are located in waters already experiencing ocean acidification. It’s not just bivalves or the creatures that eat them that are at risk. Freshly caught tanner crabs in Alaska (Alaska Department of Fish and Game) Ocean acidification has the potential to change species composition and abundance, which can significantly alter the marine food web in Alaska. Coastal Alaska waters face more immediate threats from ocean acidification than anywhere else in the global ocean because of the low pH of the northern Pacific Ocean and the effects of cold water on ocean chemistry. Ocean acidification refers to a reduction in the pH of the ocean over an extended period time, caused primarily by uptake of carbon dioxide (CO 2) from the atmosphere.For more than 200 years, or since the industrial revolution, the concentration of … Chancellor.

Share: Share to Twitter Share to Facebook Share by email Print. Ocean acidification is a problem created by the increasing levels of carbon dioxide in our atmosphere, and it is harmful to certain plankton, shellfish, coral, and marine plants. The worst socio-economic consequences of acidification will fall on the southwestern and southeastern coasts of the Alaska. Increasing ocean acidity affects Alaska crabs’ shells Valuable fisheries face greater uncertainty. Scientists in Alaska have been studying the effects of ocean acidification on crabs. Over the last 250 years, the oceans have absorbed 560 billion tons of CO 2, increasing the acidity of surface waters by 30%. RIS [PDF … NOAA and collaborators have compiled data about OA conditions for the entire continental shelves of North America, from Alaska to Mexico in the west and from Canada to the Caribbean in the east.
