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 […]

NCCOS Living Shorelines Research Attracts International Audience

A delegation from the Ecosystem Conservation Society of Japan (ECS-J) recently visited the NCCOS laboratory in Beaufort, NC to learn about living shorelines.  ECS-J is the largest conservation group in Japan, and works with environmental organizations, government agencies and research groups in Japan and abroad to promote environmental conservation. The visit was prompted by the […]

Real-time HAB and Toxin Sensors Deployed in Pacific Northwest

An environmental sample processor (ESP) was deployed on May 23 to monitor for harmful algal blooms (HABs) and their toxins off the coast of La Push, Washington in the Olympic Coast National Marine Sanctuary, by scientists with NOAA and the University of Washington. This is the first time the ESP, essentially a ‘lab in a […]

Robotic Environmental Sample Processor Conserves Samples for HAB Species Identification

Sponsored researchers with the NCCOS ECOHAB project looking at regional harmful algal bloom “hotspots” off coastal California are testing the feasibility of using a robotic water quality and toxin detection device, the Environmental Sample Processor or ESP, to collect the glass cells (silicon frustules) of the diatom Pseudo-nitzschia for species identification and assessing geographic distribution. Certain species […]

NCCOS Provides Training to a Centralized Algal Toxin Testing Laboratory for Southeast Alaskan Tribes

NCCOS scientists provided training and technical guidance to scientific staff of the Sitka Tribe of Alaska Environmental Regulatory Laboratory (STAERL) on the extraction and detection of Paralytic Shellfish Toxins (PST). The NCCOS-developed receptor binding assay being taught, an Interstate Shellfish Sanitation Conference (ISSC) accepted method, can help secure the food supply against these potent toxins. […]

NCCOS Investigates Natural Control of HABs

NCCOS sponsored research at the University of Delaware is testing the capability of a naturally occurring bacteria Shewanella to chemically control or mitigate harmful algal blooms (HABs). Bacteria are thought to regulate algal abundance in the environment, and several species of algicidal (algae-killing) bacteria were evaluated in laboratory experiments. However, few algicidal compounds produced by bacteria have […]

NCCOS Research Transitions GrouperChek to Commercialization

Is this really grouper that I am eating? In order to answer this question, NCCOS sponsored scientists at the University of South Florida (USF) developed and patented a quick identification device for commercially important grouper species. A technological offshoot from a portable red tide detection sensor, the apparatus checks for mislabeled “grouper” fish sold at restaurants […]
