Baseline Assessment of Marine Ecosystems in St. John Aids Coastal Management

A new NCCOS study presents baseline information about the ecology and pollution stress in Coral and Fish Bays in St. John, U.S. Virgin Islands. The information will help support evaluations of the effectiveness of watershed management activities, including those funded through the American Recovery and Reinvestment Act. The study quantified the biogeographic status of the […]

Marine Life in Gulf of Mexico Face Multiple Challenges

By Maggie Broadwater, Guest Blogger from NOAA’s Harmful Algal Bloom Analytical Response Team. Animals living in coastal waters can face a number of environmental stressors—both from nature and from humans—which, in turn, may have compounding effects. This may be the case for marine life in the Gulf of Mexico, which experience both oil spills and the […]

NOAA Conducts Field Mission to Assess Contaminants in American Samoa

Researchers from the National Centers for Coastal Ocean Science (NCCOS), in collaboration with partners from NOAA’s Coral Reef Conservation Program, recently completed a major field effort to quantify pollution in the Faga’alu Bay watershed in American Samoa. Faga’alu Bay has been designated as a U.S. Coral Reef Task Force priority watershed and is a focus […]

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 […]

Sunscreen Chemical Threatens Coral Reefs

Researchers from the National Centers for Coastal Ocean Science (NCCOS) and their partners have discovered that a sunscreen chemical commonly used in many soaps, cosmetics, and body fragrances is highly toxic to the larvae of the coral Stylophora pistillata. The team’s data show that even very low concentrations of benzophenone-2 (BP-2) can quickly kill juvenile […]

New Study Shows Elevated Sediment Pollution Levels in Guánica Bay, Puerto Rico

A new study from the National Centers for Coastal Ocean Science (NCCOS) reports recent sediment samples from Guánica Bay, Puerto Rico contained some of the highest concentrations of PCBs, chlordane, chromium, and nickel ever measured in the history of the NCCOS National Status & Trends Program, a nationwide contaminant monitoring program that began in 1986. […]

Some Gulf Dolphins Are Gravely Ill Following Deepwater Horizon Oil Spill

Bottlenose dolphins in Louisiana’s Barataria Bay have lung damage and adrenal hormone abnormalities not previously seen in other dolphin populations, according to a new study published Dec. 18, 2013 in the journal Environmental Science & Technology. The study was conducted in August 2011 by a team of government, academic, and non-governmental researchers as part of […]

Helping Millersville University Students Understand Eutrophication and Consider Careers in Science

Dr. Suzanne Bricker from NOAA’s Center for Coastal Monitoring and Assessment recently gave a guest lecture on eutrophication at Millersville University in Millersville, Pa. The lecture—“Eutrophication (nutrient pollution) in U.S. Coastal Waters and Elsewhere”—described current nutrient-related water quality conditions in U.S. estuaries and changes since the early 1990s, the factors influencing development of observed problems, […]
