While, the negative impacts of increasing ocean acidification on clams, scallops and other bivalves the biological basis is still unclear, “legacy effect” of early CO2 explosure can play a significant role in bivalve population dynamics. NCCOS-funded researchers performed a series of experiments to look at the days-to-months impacts of carbon dioxide (CO2) on the larvae of northern quahogs [...]

A recently published study into how Heterosigma rapidly forms blooms discovered a remarkable behavior: they flee. This fish-killing species of microscopic plant swims away when it senses single-celled predators are feeding on others nearby. In response, they take “shelter” in low salinity water layers which the predators find intolerable. The investigators said they had never seen a plant swim [...]

NCCOS-funded scientists working under the auspices of the NOAA Ocean Acidification Program were recently introduced to the internal research community at special roll-out and open discussion at the Third International Symposium on the Ocean in a High-CO2 World. Three U.S. ocean acidification researchers were recently awarded NOAA Ocean Acidification Program extramural funding. The roll-out introduced [...]

Dredging channels and cleaning boat hulls or fishing gear in or near established Didemnum colonies can create fragments of these invasive organisms that survive in the water column up to four weeks, disperse long distances, and even reproduce before resettling, possibly in new areas, according to NOAA research. The article suggests that cleaning equipment on land and reducing bottom disturbance [...]

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, represented at NOAA by the National Centers for Coastal [...]

National Centers for Coastal Ocean Science researchers and their collaborators found that ten invasive tunicate species are fouling shellfish aquaculture operations along much of the U.S. East Coast, causing decreased growth rates, increased mortality, and high maintenance costs. The survey identified the locations of highest fouling, which will be used to develop a plan to [...]

National Centers for Coastal Ocean Science (NCCOS)-sponsored scientists from the University of Rhode Island, Brown University, University of Connecticut, Virginia Institute of Marine Science, and Narragansett Bay Estuary Program are working closely with state managers to assess the ecosystem responses to nitrogen load reductions and to develop a forecast model as a critical adaptive management [...]
