Tenacity of Brown Tides Linked to Flexible Transcriptome

Research sponsored by the National Centers for Coastal Ocean Science (NCCOS) discovered that the genetic flexibility of the single-celled harmful algae, Aureococcus anophagefferens, persistently blooms in what are known as “brown tides.” Scientists performed transcriptome profiling (looking at a cell’s RNA produced by gene transcription) on an A. anophagefferens strain to assess its response to common environmental stressors occurring in […]

What Powers Florida Red Tides?

The results of a long-term research project, sponsored by NOAA’s National Centers for Coastal Ocean Science, focused on the Gulf of Mexico red tide are featured in a special issue of the scientific journal Harmful Algae. History records blooms of the harmful Florida red tide (caused by the microalgal dinoflagellate Karenia brevis) occurring centuries before Florida’s mid-late […]

Algal Toxins Pose Health Risk to Dogs

Harmful algal bloom (HAB) toxins, including microcystins, pose health threats and even death for dogs and other pets exposed to the contaminated water, explains a new educational brochure from the New York Sea Grant Program. The brochure, a product of a National Centers for Coastal Ocean Science sponsored research project in the Great Lakes, describes freshwater HABs and their […]

Glider Begins Second Deployment to Monitor Threatening Florida Red Tide

A red tide of Karenia brevis in the Gulf of Mexico continues its slow advance toward Florida’s southwest coast. NOAA’s National Centers for Coastal Ocean Science (NCCOS) rapid response emergency funding is supporting a second deployment of underwater robotic gliders to track subsurface movement of the red tide. Since mid-July, a large red tide has lingered […]

NCCOS Scientist to Advise Shellfish Sanitation Experts on Harmful Algae Lab Methods

The National Centers for Coastal Ocean Science’s (NCCOS) Dr. Quay Dortch will join the Interstate Shellfish Sanitation Conference (ISSC) as an expert advisor. Dr. Dortch’s advice and expertise will contribute to one of the most technical and specialized areas of shellfish sanitation, that of laboratory methods for detecting and testing harmful algal toxins and their syndromes. […]

Common Coastal Seaweeds Release Toxins Harmful to Marine Organisms

A new study has found that compounds excreted by common coastal green seaweeds, or sea lettuce, detrimentally affect other organisms. The green seaweed Ulvaria obscura forms blooms in the intertidal and subtidal zones. During high spring tides, this seaweed strands on the shore and succumbs to drying, high levels of sunlight, and high temperatures. These […]

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 […]
