Gliding into the Future of Ocean Acidification Observing

NOAA Ocean Acidification Program

The technology used to observe ocean acidification - the shift in ocean chemistry driven by an increase in the amount of carbon dioxide in the atmosphere due to the burning of fossil fuels and other human activities - has followed the same trend of innovation and scaling as computer technology. Measuring ocean chemistry traditionally involves a team of scientists to collect samples at sea and an entire lab team to analytically determine the carbonate chemistry by measuring multiple parameters, including pH. While these methods are still being used, innovations in technology have made continuous pH sampling in our ocean possible. Dr. Grace Saba, an assistant professor at Rutgers University, has worked to develop a new sensor and is leading a project that will combine this new technology, existing data, and modeling to optimize the ocean acidification observing network in the Northeast US.

Marine Shellfish Populations Estimated to be at Risk from Ocean Acidification

Marine Shellfish Populations Estimated to be at Risk from Ocean Acidification

NOAA National Centers for Coastal Ocean Sciences

The absorption of rising atmospheric carbon dioxide (CO2) into the oceans has caused ocean acidification and associated shifts in marine carbonate chemistry. In coastal waters, excessive nutrient runoff can also create regions of low oxygen, high CO2, and acidification. These conditions have been shown to be detrimental to growth and survival of larval and juvenile shellfish such as oysters, clams and scallops in laboratory studies, but the consequences of these effects on wild populations have been unknown.

Now, a new publication shows that the levels of impairment observed in laboratory experiments have the potential to cause increased risk to wild populations of marine bivalves in the northeastern USA.

New Insights into the Complexity of Estuarine Acidification Seminar

This virtual seminar will focus coupled a comprehensive measurement program to retrospective and future model simulations to quantify controls on estuarine acidification in Chesapeake Bay,a large estuarine complex with strong gradients of salinity, oxygen, metabolicrates, and bathymetry. Researched found that estuarine acidification may be even more complex (and interesting!) than originally posited, owing to self-buffering processes within macrophyte communities, connections of acidification rates to watershed management aimed at oxygen improvements, and a varying buffering of acidification through altered carbonate chemistry within freshwater sources. This new understanding presents both challenges and opportunities to managing future acidification along the coast.

Letters of Intent Due January 24th, 2020

FEDERAL FUNDING OPPORTUNITY: Regional Vulnerability Assessments for Ocean Acidification

The Ocean Acidification Program is soliciting proposals for collaborative projects of up to 3 years in duration that synthesize ocean acidification information at a regional scale (e.g. Large Marine Ecosystem, large estuary or collection of small estuaries, and state or collection of states in US waters) to determine where societal vulnerabilities to ocean acidification exist or are emerging, in order to provide actionable information for marine resource decision makers. This funding opportunity will not support the collection of new chemical or ecological observations or species response data. Social science data collection is permitted.

Information about this opportunity can be found here:https://www.grants.gov/web/grants/search-grants.html?keywords=11.017 This grant is Funding Opportunity Number: NOAA-OAR-OAP-2020-2006333.  Email Letters of Intent to erica.h.ombres@noaa.gov. Full proposals should be submitted through grants.gov

Important dates:  Letters of Intent are due January 24th and full proposals are due March 27th.

Ocean Acidification: Building on a Foundation at the Flower Garden Banks Sanctuary

Ocean Acidification: Building on a Foundation at the Flower Garden Banks Sanctuary

NOAA Ocean Acidification Program

Looking up at high-rise buildings, towering cathedrals, or the great pyramids at Giza; the feats of man seem unimaginable. The key to these massive architectural achievements is laying a quality foundation. Dr. Xinping Hu, an associate professor at Texas A&M Corpus Christi University, knows that a solid foundation is very important in science as well. Together with his co-investigators at NOAA’s Atlantic Oceanographic and Meteorological Lab (AOML), Texas A&M University, and Texas A&M University-Corpus Christi, Dr. Hu will be building upon a foundation of data collected both at and near the Flower Garden Banks National Marine Sanctuary (NMS) in the northwestern Gulf of Mexico to better characterize the changes in ocean chemistry over space and time in these waters.

There are many facets to a strong structure, architectural or scientific. Having the right tools and site to build, along with a skilled team of craftsmen, and an insightful foreman are all integral to conduct impactful science.
