Ocean Acidification More Rapid in Coastal Oceans

New research under the joint NCCOS Competitive Research Program and NOAA Ocean Acidification Program finds the combined effects of anthropogenic and biological carbon dioxide (CO2) inputs may lead to more rapid acidification in Chesapeake Bay and other coastal water compared to the open ocean. The results indicate that eutrophication can exacerbate ocean acidification (OA) where […]

NOAA Builds Relationship for Resource Management with Wampanoag Tribe

Last March, NCCOS joined other NOAA partners in a roundtable event with the Mashpee Wampanoag Tribal Council, sponsored by the NOAA North Atlantic Regional Collaboration Team. The meeting facilitated partnerships and the exchange of ideas between the Mashpee Wampanoag Tribe and NOAA regarding fisheries, habitat, and water quality. Historical records show the Algonquian-speaking Wampanoag encountered the English colonists of the […]

Collaboration with new Scholar and NOAA Ocean Acidification Program Show Potenital

This past month, NCCOS welcomed a new Hollings Scholar, Madison Uetrecht, who will study the effects of ocean acidification on oyster growth under Dr. Beth Turner over the summer months. They visited Mook Sea Farm, where Uetrecht will conduct out-planting experiments with juvenile oysters to assess whether shell growth and calcification changes during different field ocean acidification (OA) conditions. […]

NCCOS Research on Display at 2017 Aquatic Sciences Meeting

From February 26 to March 3, 2017 the Association for the Sciences of Limnology and Oceanography (ASLO) held its biennial Aquatic Sciences Meeting in Honolulu, Hawai′i. NCCOS scientists and sponsored investigators shared their research results with thousands of limnologists and oceanographers from around the world. Topics included harmful algal blooms, hypoxia, science to management applications, […]

Winners and Losers in the California Current under Future Ocean Acidification

A NOAA-supported study projects that Dungeness crab and some commercial finfish species living on the sea floor may decline in future years due to increased ocean acidification in the California Current. These estimates were based on computer models forecasting changes in the California Current ocean ecosystem, which includes an expected rise in summer ocean acidification […]

Shellfish Larvae Struggle in Fluctuating Oxygen and Acidity in Estuaries

A study supported by NCCOS and the NOAA Ocean Acidification Program found that interacting effects of acidified and low oxygen (hypoxic) waters reduced the survival, growth, and development of larval stages of three important shellfish species: bay scallops, hard clams and eastern oysters. Shellfish larvae were exposed to ideal, acidified and low oxygen conditions both individually and in […]

Sensitivity of California Current Species to Ocean Acidification

A new study estimated the sensitivity of different groups of marine species to ocean acidification (OA) within the California Current ecosystem. Species groups were designated based on having similar functions in the ecosystem (i.e. urchins, oysters, phytoplankton, zooplankton), and the OA sensitivity for each group was determined based on previous studies. Most functional groups of species (26 of 34) responded negatively to […]

NCCOS Briefs Environmental Legislators on Harmful Algal Blooms

Earlier this month, Dr. Quay Dortch (manager of the NCCOS Ecology and Oceanography of Harmful Algal Blooms Program) addressed the Oceans and Coast sub-group of the National Caucus of Environmental Legislators (NCEL). At the Chicago meeting of the sub-group, Dortch described the causes and impacts of harmful algal blooms, federal and state responses, and recommended incorporating […]
