NCCOS Provides Florida Agency Specialized Training in Harmful Algal Bloom Monitoring

Earlier this month, NCCOS researchers provided a visiting scientist from Florida’s Fish and Wildlife Conservation Commission’s (FWC) Red Tide Monitoring Program training on the use of physiological biomarkers for harmful algal bloom monitoring. Coastal blooms of the microscopic alga Karenia brevis, also known as red tides, occur nearly annually in the Gulf of Mexico and […]

Next-generation HAB Detectors are Smaller, Cheaper, and Getting Attention

Two instruments developed with NCCOS support are revolutionizing the detection of harmful algal blooms (HABs). The Environmental Sample Processor, or ESP, and the Imaging Flow Cytobot, or IFCB, are receiving more attention from scientists and managers and are the focus of an August 2014 article in the journal Environmental Health Perspectives. The article describes the […]

NOAA and Partners Monitor Large Red Tide in Gulf of Mexico off Southwest Florida

A large harmful algal bloom (HAB) of the Florida red tide organism Karenia brevis remains offshore of Florida’s southwest coastal counties, causing growing concern among Florida wildlife managers and public health officials. Depending on the winds and currents, the HAB could possibly reach some of Florida’s most popular tourist beaches within a week. The bloom caused an on-going […]

NCCOS Promotes Shellfish Aquaculture to Improve Water Quality

Researchers are exploring the role oyster aquaculture may be playing in improving water quality in the Chesapeake Bay. On July 16, 17, and 23, 2014,  the researchers made visits to three Chesapeake Bay oyster growers to discuss their culture practices, to view their lease areas, and to share information about this joint project. The project also  involves development […]

Red Tide Toxin Metabolite Accumulates in Organs, May Pose Greater Risk to Shellfish Consumers

In 2012, the state of Texas experienced the longest red tide on record, leading to a collapse of its oyster industry. Red tides in the Gulf of Mexico affect humans, wildlife, fisheries, and the regional tourist-related economy. They are caused by the harmful algae Karenia brevis, which release a neurotoxin called brevetoxin that accumulates in exposed shellfish and […]

The National Coral Reef Monitoring Program begins “Puerto Rico” Phase

This summer, National Centers for Coastal Ocean Science (NCCOS) researchers began collecting data on coral reefs around the island of Puerto Rico to help local natural resource managers address coral reef management concerns as part of the National Coral Reef Monitoring Program’s “Puerto Rico phase.” This program collects standardized biological, physical, and socioeconomic monitoring data […]

Coastal Ocean Acidification: The Other Eutrophication Problem

Eutrophication, or increased nutrient loading to estuaries, causes algae to bloom and consequently coastal hypoxia (low oxygen waters) when the algal biomass decomposes. Often overlooked, eutrophication can also produce carbon dioxide, which leads to a lowering of seawater pH (or increasing acidity). A recent invited paper by scientists supported by NCCOS and the NOAA Ocean Acidification Program shows low […]

Average 2014 Gulf of Mexico ‘Dead Zone’ Confirms NOAA-supported Forecast

National Centers for Coastal Ocean Science supported scientists documented that the 2014 “dead zone” (area of hypoxia, or low oxygen) in the northern Gulf of Mexico west of the Mississippi River delta now covers 5,052 square miles of sea floor, or about the size of the state of Connecticut. Though average in size and smaller than last year, […]
