Changes in Climate Could Make Pesticides More Toxic to Estuarine Organisms

During a recent climate webinar offered as part of the NOAA Science Day seminar series, NCCOS’s Marie DeLorenzo explained how changing climate variables may influence pesticide toxicity in the coastal zone. Pesticides enter estuarine waters via runoff and drift from agricultural, turf grass, home and garden, and mosquito control applications. DeLorenzo tested adult and larval […]

Could Future Land Use Changes Increase Storm Surge Flooding?

Scientists funded by the National Centers for Coastal Ocean Science have found that projected changes in coastal Gulf of Mexico land use and land cover could increase the extent of storm surge flooding by up to 70 percent above flooding from projected sea level rise alone. Using a newly developed predictive model, the University of […]

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, […]

Sea Level Rise Research Supports Gulf of Mexico Sentinel Site Cooperative

An NCCOS-funded study is investigating the ecological effects of sea level rise in the Gulf of Mexico. The effort is the focal point of the Northern Gulf of Mexico Sentinel Site Cooperative, a federal–state partnership established to advance sea level rise prediction and assessment capabilities. The cooperative seeks to improve coastal data and research products […]

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 […]

North Carolina Coastal Atlas Debuts with NCCOS Support

Building on nearly 10 years of NCCOS-sponsored research on sea level rise in North Carolina, a multi-institutional team led by East Carolina University recently launched a new online coastal mapping and information system. The North Carolina Coastal Atlas is an interactive system that combines physical, ecological, and human use data to support education and coastal […]
