NCCOS Expertise Contributes to U.S. National Climate Assessment

Four NCCOS scientists wrote a NOAA technical report on “Oceans and Marine Resources in a Changing Climate” that led to a chapter in the Third National Climate Assessment (2013), produced by the U.S. Global Change Research Program. Carol Auer, Quay Dortch, Elizabeth Jewett, and Cary Lopez participated in this comprehensive review, wherein 63 experts examined […]

Interagency Working Group Aims for Better Collaboration on Understanding How Nitrogen Pollution is Linked to Climate Issues

The U.S. Global Change Research Program (USGCRP) recently convened a federal working group to address the linkages between climate and nitrogen pollution in the environment.  The goal of the group is to leverage and coordinate federal (NOAA, EPA, USGS, USDA, DOE, NSF) intramural and extramural research activities to enhance the knowledge base on this issue. […]

Zooplankton Show Ability to Adapt to Stress of Starvation and Climate Change

NCCOS sponsored research on zooplankton response to Harmful Algal Blooms has also yielded information on how zooplankton respond to climate change and environmental stress. Zooplankton play a central role in food webs from phytoplankton to fish and are also important in the biogeochemical cycles of lakes and oceans. Two recent studies from Dr. Hans Dam […]

Ocean Acidification: NCCOS-funded Research Reveals Legacy Effect of Early Larval CO2 Exposure on Bivalve Survival and Growth

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 […]

NOAA Ocean Acidification Program Finds Supportive Partner in NCCOS

NCCOS-funded scientists working under the auspices of the NOAA Ocean Acidification (OA) Program were recently introduced to the internal research community at a 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 […]

Ocean acidification emerges as new climate threat – The Washington Post

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 […]

Excess Algae Responsible for Hotspots of Increased Ocean Acidification

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 […]

“New” CO2 Source Spells Trouble for Marine Life | Mother Jones

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 […]
