Ocean Sciences Meeting Highlights Results of Sponsored Research

The 2014 Ocean Sciences Meeting showcased the reach and extent of research sponsored by NCCOS, including coral reefs, harmful algal blooms, hypoxia, applying research to management solutions, and integrated ecosystem assessments. NCCOS staff and sponsored research scientists gave over 25 oral and poster presentations and co-chaired a special session on mapping, monitoring, and managing mesophotic […]

Tackling Ocean Acidification in Maine

Ocean chemistry is rapidly changing due to rising levels of atmospheric carbon dioxide, which has increased the acidity of seawater worldwide. Ocean acidification can affect marine resources such as fish and shellfish and may be particularly acute in Gulf of Maine waters because low temperatures and runoff from the land can exacerbate acidic conditions. On […]

Ocean Acidification Promotes Disruptive and Harmful Algal Blooms on Our Coasts

The general decline in ocean pH (i.e., more acidic conditions) from the increasing concentrations of carbon dioxide (CO2) is well documented. Also well documented are increased nutrients entering coastal waters often promoting excessive and ecosystem disruptive algae blooms, including harmful algal blooms. The decay of these coastal blooms promotes bacterial respiration resulting in increased CO2, […]

NCCOS Research in Today’s Rapidly Changing Global Environment

Two national science conferences recently highlighted NCCOS research: The theme at the 7th Symposium on Harmful Algae in the United States (Oct. 27–31, 2013; Sarasota, FL) was harmful algal blooms (HABs) in a changing world, especially a more acidic one. NCCOS HAB scientists and sponsored researchers  organized, advised,  chaired sessions, and presented some 13 oral […]

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 […]
