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 […]

Monitoring Oregon Coastal Harmful Algae Helps Forecasting Blooms

The ongoing West Coast harmful algal bloom (HAB) highlights the need for improved regional monitoring of toxic algae in the California Current along the coasts of California, Oregon, and Washington. A first of its kind Oregon HAB monitoring and research pilot project demonstrated a viable strategy to address state management needs and fill a critical […]

New Coral Area Discovered in 2014 in the Gulf of Mexico is Two Times Larger than Previously Thought

Preliminary results from the fourth and final Coral Ecosystem Connectivity expedition (22 August – 4 September 2015) to Pulley Ridge (off the southwest coast of Florida) show the new coral area discovered in 2014 is two times larger than previously thought. Pulley Ridge, the deepest photosynthetic reef off the continental U.S., is one of the […]

Study Supports EPA to Control Both Nitrogen and Phosphorus in Freshwaters

One of the most common bloom-forming cyanobacteria (blue green algae) in freshwater ecosystems is Microcystis, which produces the liver toxin microcystin. Like many cyanobacteria, blooms of Microcystis are associated with higher temperatures and the availability of nitrogen (N) and phosphorus (P). Many freshwater ecosystems are P-limited, meaning P plays the key role in the occurrence of most cyanobacteria blooms, […]

National Coastal Ocean and Estuary Conference Provides Platform for NCCOS Research

The 23rd biennial Coasatal and Estuarine Research Federation Conference (CERF), held in Portland, Oregon this November, highlighted the scope of research sponsored by NCCOS including harmful algae and their toxins and ocean acidification and hypoxia (low dissolved oxygen) interactions. NCCOS exclusively hosted a major session and co-hosted a second major session with the NOAA Office of Oceanic […]

Ciguatera Fish Poisoning Predicted to Increase with Rising Ocean Temperatures

A new NOAA study, published in the journal Ecological Modeling, anticipates an increase in the incidence of ciguatera fish poisoning (CFP) in the Gulf of Mexico and the U.S. Southeast Atlantic coast with predicted rising global ocean temperatures due to climate change. Stable or slightly lower risks of CFP are forecasted for the Caribbean Sea. Researchers from […]

NCCOS Delivers Hard Truths on Hardened Shorelines in the Mid-Atlantic

NCCOS-sponsored researchers have found that hardened shorelines have negative effects on fish; invertebrates, such as oysters and crabs; and submerged aquatic vegetation. Shoreline hardening is an attempt to stabilize coastal land and protect residential and commercial infrastructure along the coast by building structures, like seawalls, to hold back the sea and prevent the loss of sediment. […]

West Coast Harmful Algal Bloom Draws Attention of Congress

An ongoing toxic algal bloom off the U.S. West Coast was first detected in California in May 2015 and soon stretched to Alaska. Formed by the harmful algae Psuedo-nitzschia, this unusually long-lasting bloom is the largest bloom in the past 15 years. Record-setting concentrations of domoic acid, the neurotoxin produced by the bloom, have shut […]
