NCCOS Research Featured in EPA Webinar Series on Inland Harmful Algal Blooms

On Jan. 14, NCCOS researchers Steve Morton and Rick Stumpf were featured speakers at an Environmental Protection Agency (EPA) webinar focused on inland harmful algal blooms. The event was part of an EPA webinar series intended to build awareness about the effects of nutrient pollution and harmful algal blooms on the environment. Dr. Morton provided […]

Ocean Acidification Promotes Disruptive and Harmful Algal Blooms on Our Coasts

The general decline in ocean pH (i.e., more acidic conditions) from the increasing concentrations of carbon dioxide (CO2) is well documented. Also well documented are increased nutrients entering coastal waters often promoting excessive and ecosystem disruptive algae blooms, including harmful algal blooms. The decay of these coastal blooms promotes bacterial respiration resulting in increased CO2, […]

NCCOS Identifies Cause of Large Fish Kills in North Carolina Estuaries

In recent years, North Carolina estuaries have experienced large fish kills often associated with rains and moderate temperatures. Most of the dead fish have exhibited large, open skin ulcers. Scientists at NCCOS analyzed the ulcerated fish collected by the North Carolina Department of Environment and Natural Resources (NCDENR) and the Neuse Riverkeeper Foundation using molecular assays […]

NCCOS Research in Today’s Rapidly Changing Global Environment

Two national science conferences recently highlighted NCCOS research: The theme at the 7th Symposium on Harmful Algae in the United States (Oct. 27–31, 2013; Sarasota, FL) was harmful algal blooms (HABs) in a changing world, especially a more acidic one. NCCOS HAB scientists and sponsored researchers  organized, advised,  chaired sessions, and presented some 13 oral […]

Helping Alaska Tribe Launch a Harmful Algal Bloom Monitoring Program

The NCCOS Event Response Program is funding a project to assist the Sitka Tribe of Alaska and other communities in southeast Alaska establish a harmful algal bloom (HAB) monitoring program for recreational and subsistence shellfisheries. In October, two cases of paralytic shellfish poisoning (PSP) were reported by the state and were linked to butter clams […]

NCCOS Calibrates Harmful Algal Bloom Toxin Sensors in California

An NCCOS scientist visited the Monterey Bay Aquarium Research Institute on Nov. 6–13 to perform critical calibration of NCCOS-developed domoic acid sensors on two robotic Environmental Sample Processors (ESPs). Results of these calibrations and the analysis of controlled test samples will allow researchers to accurately quantify harmful algal bloom toxin data generated during two ESP […]

NCCOS Continues to Help Pennsylvania Respond to Lake Erie Harmful Algal Bloom

Following the first reported cyanohab bloom in Presque Isle State Park in July 2013, the NCCOS Harmful Algal Bloom (HAB) Rapid Response Team supported the Pennsylvania Department of Environmental Protection (PADEP) as they mobilized to address public concerns about toxins, recreational restrictions, and health advisories. This aid helped keep swimmers in the popular park safe, […]

High Tech Sensors Used to Investigate Harmful Algal Bloom ‘Hot Spots’ in California

NCCOS scientists and their partners from the Monterey Bay Aquarium Research Institute (MBARI) are investigating the causes of Pseudo-nitzschia blooms and toxicity in Monterey Bay, Calif. from Sept. 5 to Oct. 10. Under the right conditions, some Pseudo-nitzschia produce domoic acid, a potent neurotoxin. Domoic acid accumulates in fish and shellfish, has caused bird and […]
