Volunteers Train to Monitor Florida Red Tide in Real Time

Citizen volunteers and college students are evaluating an NCCOS-funded portable sensor that easily and accurately calculates the number of Karenia brevis cells in a water sample, the algae that causes red tides in Florida. This month, St. Petersburg College biotechnology students learned how to use the sensor in a training class at the University of […]

Producing a new Reference Material for Paralytic Shellfish Toxin Monitoring

Saxitoxins, produced by species of harmful algal blooms (HABs), cause paralytic shellfish poisoning (PSP) when contaminated seafood is consumed. For nearly 50 years the U. S. Food and Drug Administration (FDA) has provided a saxitoxin dihydrochloride standard to state shellfish laboratories and others who monitor seafood safety, and has distributed it as a National Institutes of Standards […]

Gulf of Mexico Phytoplankton Communities Altered after Deepwater Horizon Oil Spill

On April 20, 2010, an explosion on the Deepwater Horizon oil drilling platform released millions of barrels of oil into the Gulf of Mexico, making it the largest marine oil spill in U.S. history with documented negative impacts to zooplankton, fish, birds, sea turtles, and marine mammals. Now, new research partially funded by NCCOS has disclosed negative impacts […]

Measuring Sunscreen Chemicals in South Carolina Coastal Waters

A recent NCCOS study in Marine Pollution Bulletin investigated the distribution of five sunscreen ingredients (oxybenzone, octocrylene, avobenzone, padimate-O, and octinoxate) measured in the coastal waters of South Carolina.  Sunscreen chemicals are increasingly used in personal care products to protect the skin from the damaging effects of UV radiation; however, laboratory studies showed that some of these chemicals […]

NCCOS’s Mussel Watch Program to Assess Chesapeake Bay for New and Emerging Water Pollutants

Scientists from NCCOS are partnering with the Maryland Department of Natural Resource (MD-DNR) to launch a monitoring project in the Chesapeake Bay designed to survey the magnitude and distribution of contaminants of emerging concern (CECs). CECs, such as current-use pesticides, pharmaceuticals, personal care products, and other chemicals associated with human activities, can enter the environment […]

NOAA Partnership Helps Design Coral Reef Water Quality Monitoring Program

In an effort to design a water quality monitoring program for the Southeast Florida Coral Reef Initiative (SEFCRI) region, Florida’s Department of Environmental Protection (DEP) met with coastal county representatives and scientists from across NOAA: National Centers for Coastal Ocean Science (NOS), the Atlantic Oceanographic and Meteorological Lab (OAR) and the Habitat Conservation Division (NMFS) at […]

Alaskan Tribal Communities Trained for Testing Paralytic Shellfish Toxins

Last October, two cases of paralytic shellfish poisoning (PSP) were confirmed  after butter clams containing PSP toxins were harvested for personal consumption from a beach near Sitka, Alaska. Elevated PSP levels have prompted the state to close most southeast Alaska commercial shellfishery areas. However, recreational and subsistence shellfishers in the region remain at risk to […]

Additional Toxin Data Helped Ohio Deliver Safe Drinking Water After August Cyanobacteria Bloom

Persistent concerns about toxins in Toledo, Ohio’s drinking water following August’s large, cyanobacteria bloom in Lake Erie prompted a follow-up investigation supported by NCCOS. At the time, the bloom led the City of Toledo to issue a two-day, drinking water ban for 400,000 people in Toledo and surrounding areas after drinking water samples showed high […]
