New Study Shows Complex Variation of Toxicity in Two Closely Related HABs

A recent study funded by the National Centers for Coastal Ocean Science  investigated the role of specific phosphorus and nitrogen compounds in determining the amount and composition of Paralytic Shellfish Poisoning-causing toxins in cultures of two harmful algal bloom (HAB)-forming dinoflagellates from Hong Kong, Alexandrium catenella and Alexandrium tamarense.  Growth and toxicity of even these […]

Ciguatera Assays Aim to Improve the Safety of Tropical Seafood

Researchers from the National Centers for Coastal Ocean Science developed effective, inexpensive molecular lab tests for field samples to detect algae responsible for a widespread seafood-borne illness. In this month’s Journal of Phycology, the scientists describe assays to detect and quantify six species of Gambierdiscus that cause ciguatera fish poisoning in the Atlantic, Caribbean, and […]

ESA declares end of mission for Envisat | SpaceRef – Your Space Reference

Just weeks after celebrating its tenth year in orbit, communication with the Envisat satellite was suddenly lost on 8 April. Following rigorous attempts to re-establish contact and the investigation of failure scenarios, the end of the mission is being declared. A team of engineers has spent the last month attempting to regain control of Envisat, […]

NOAA and Korea Continue Partnership to Establish HAB Species Detection Capabilities

Two scientists from the Korean Ocean Research and Development Institute (KORDI) visited the NOAA/NOS/NCCOS Marine Biotoxins Program laboratory in Charleston, SC April 2 – 6 to develop a detection method for the fish-killing dinoflagellate Heterocapsa. This organism causes devastating fish kills in neighboring Japanese waters and is considered a high potential threat to the economically […]

International Joint Commission Committed to Address Nutrient Problems in Lake Erie

Lake Erie is the shallowest and smallest of the Great Lakes by volume and is heavily influenced by agricultural and urban runoff.  It is subject to periodic outbreaks of harmful algal blooms (HABs) and hypoxia. These problems were identified as the highest priority of the International Joint Commission (IJC) as it drafts guidelines and targets […]

Sustainable Aquaculture Strategies Exchanged at International Workshop

Dozens of experts from Scotland, Denmark, Canada, Mexico, and the U.S. convened in Silver Spring on March 20-21 to share insights into marine cage culture’s effects on the environment and the latest strategies to reduce them. To support growth of the U.S. aquaculture industry while maintaining environmental sustainability, Federal, state and local managers and regulators exchanged […]

NCCOS Toxin Detection Technologies Officially Transferred to Latin American Countries

Regulatory scientists from Nicaragua, Costa Rica, El Salvador and Columbia, candidates for reference laboratories, completed two weeks of formal training for high throughput detection of toxins responsible for paralytic shellfish poison (PSP) and ciguatera fish poisoning (CFP). The course of study was provided by National Centers for Coastal Ocean Science (NCCOS) scientists at Charleston, SC […]
