Scientists Gather from Around the World to Develop a Global Ocean Acidification Observing Network

Scientists Gather from Around the World to Develop a Global Ocean Acidification Observing Network

NOAA Ocean Acidification Program

NOAA, academic and international scientific experts are gathering July 24 -26, to further develop the Global Ocean Acidification Network (GOA-ON).  The purpose of this network is to facilitate international coordination in order to compare and integrate observational data collection specific to ocean acidification across the globe.  This group is designing a global standard for measuring and identifying ocean acidification and is important for establishing a global understanding of ocean acidification including its impacts on ocean life as well as humans. This network will ensure data quality and comparability, facilitated by a structured system based on common standards.   It will also assist policy-making through research products and model-based projections of future potential impacts of ocean acidification.

NOAA Scientists Look at Potential Ocean Acidification Impacts on the Puget Sound Food Web

NOAA Scientists Look at Potential Ocean Acidification Impacts on the Puget Sound Food Web

NOAA scientists at the Northwest Fisheries Science Center are beginning to understand future impacts of ocean acidification on Puget Sound’s food web. Drs. Shallin Busch, Chris Harvey, and Paul McElhany applied ocean acidification scenarios to a food web model to explore how the estuary’s food web and its ecosystem services (i.e. fisheries yield and ecotourism) may change over the next fifty years

NOAA Led Study Shows Walleye Pollock Resilience to Ocean Acidification

NOAA Led Study Shows Walleye Pollock Resilience to Ocean Acidification

Scientists at NOAA’s Alaska Fisheries Science Center recently found that some life history parameters of walleye pollock seem to be only minimally affected by high CO2 waters. Dr. Thomas Hurst and University of Alaska colleagues Elena Fernandez and Dr. Jeremy Mathis conducted multiple experiments in conditions mimicking both present day CO2 levels in high latitude waters and those predicted to occur over the next century (280-2100µatm, pH= 7.4- 8.16).

Study shows oyster reefs buffer acidification of Chesapeake Bay

Study shows oyster reefs buffer acidification of Chesapeake Bay

Virginia Institute of Marine Science

A new study co-authored by Prof. Roger Mann of 's Virginia Institute of Marine Science adds a new item to the list of oyster reef benefits — the ability to buffer increasing acidity of ocean waters.

Concerns about increasing acidity in Chesapeake Bay and the global ocean stem from human inputs of carbon dioxide to seawater, either through burning of fossil fuels or runoff of excess nutrients from land. The latter over-fertilizes marine plants and ultimately leads to increased respiration by plankton-filtering oysters and bacteria. In either case, adding carbon dioxide to water produces carbonic acid, a process that has increased ocean acidity by more than 30 percent since the start of the Industrial Revolution.
