The U.S. benefits from a wealth of resources and activities that depend on healthy coastal habitats. However, these habitats are being degraded by extensive hardening of shorelines due to climate-driven sea level rise, increasing shoreline development, land use changes in coastal watersheds, pollution, and invasions of non-native species. In the Mid-Atlantic region alone, coastal development [...]
The threat of sea level rise and storminess poses many management challenges in North Carolina due to low elevation, extensive barrier islands and vulnerability to coastal storms. The long-term North Carolina Sea Level Rise Project, part of the National Centers for Coastal Ocean Science’s Ecological Effects of Sea Level Rise (EESLR) program, has developed modeling and [...]
The Smithsonian Environmental Research Center’s DOOM lab (Dissolved Oxygen and Oyster Mortality) is examining how oysters respond to sudden drops in oxygen levels in shallow parts of the Chesapeake Bay at night. These fluctuations are partially natural, but appear to be made worse by nitrogen and phosphorus pollution. Oxygen depletion may make oysters more susceptible [...]
Project-of-the-Year Awards Showcase Program Successes Congratulations to the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program(ESTCP) Projects of the Year, recognized for research and technology developments with significant benefits to the Department of Defense (DoD). These outstanding efforts are helping DoD achieve its mission while improving its environmental performance. Resource [...]
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 [...]
Kris Holderied, who directs the National Oceanic and Atmospheric Administration’s Kasitsna Bay Laboratory, says the ocean’s increasing acidity is “the reason fishermen stop me in the grocery store.” “They say, ‘You’re with the NOAA lab, what are you doing on ocean acidification?’ ” Holderied said. “This is a coastal town that depends on this ocean, and [...]
A research paper published this week reveals that large die-offs of algae locally magnify ocean acidification. As the cells die and sinks to the bottom, the bacteria population that feeds on them swells in response, consuming more oxygen and releasing more carbon dioxide (CO2). The CO2 reacts in seawater to form acidic compounds that lower [...]
A new kind of witchy interaction is underway in the oceans, report the authors of a new paper in Environmental Science & Technology. William G. Sunda and Wei-Jun Cai created a model to predict how CO2 from water pollution—that is, runoff from chemical fertilizers (farms), human waste (sewage), and animal waste (feedlots, ranches), plus nitrogen [...]
