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, […]

NCCOS Scientists Conduct a Bioeffects Assessment in Bristol Bay, Alaska

Scientists from the National Centers for Coastal Ocean Science (NCCOS) traveled to Dillingham, Alaska on September 17–24 to collect sediments for contaminant analysis and toxicity testing, and fish tissue for histology and body burden analysis. They also conducted benthic community surveys to characterize baseline contaminant conditions in the near-shore and coastal waters of Nushagak and […]

NCCOS Scientists Assess Pollution Impacts on Corals in Commonwealth of the Northern Mariana Islands

From August 25 to August 31, NCCOS scientists will conduct field work offshore of Tinian, an island in the Commonwealth of the Northern Mariana Islands (CNMI), a U.S. territory. This research will assess the extent and magnitude of pollution stressors and their effects on coral reefs. Working in collaboration with the CNMI Division of Environmental […]

NCCOS and Partners Investigate Effects of Non-lethal Doses of Contaminants on Hawaii Corals

National Centers for Coastal Ocean Science researchers and students from Florida A&M University measured non-lethal effects of contaminants on coral health in Hawaii. Coral larvae were collected during the July spawning event and exposed to hydrocarbon and metal contaminants in a laboratory setting.  The impacts of contaminant stress were measured using coral biochemical markers and […]

NCCOS, EPA and Partners Continue Monitoring Efforts in Great Lakes “Areas of Concern”

From July 21 to August 3, NCCOS scientists and partners collected wild and recover caged mussels from a number of sites on Lake Michigan, in both Wisconsin and Michigan, for monitoring of chemical contamination and mussel health. These sites are located in what have been designated as “Areas of Concern” as part of the Great […]
