Partnerships: Bringing Scientists and Resource Managers Together to Explore Opportunities for Using Fisheries Acoustics in the Southeast US

Underwater acoustics for mapping the water column Underwater acoustics (ie. fisheries sonars) uses sound to detect and map the presence of fish and other organisms in the water column.  An acoustic signal or ping is sent into the water column from an transducer.  The strength of the return signal is measured and is correlated to […]

Researchers Report Potential for a Moderate New England Red Tide in 2012 | National Ocean Service

In April, scientists from the National Centers for Coastal Ocean Science-funded Prevention, Control, and Mitigation of Harmful Algal Blooms research project in the Gulf of Maine issued an outlook for moderate regional algal blooms in 2012. The species is a microscopic alga, Alexandrium fundyense, which blooms in New England waters every year. This alga can […]

Researchers Report Potential for a “Moderate” New England “Red Tide” in 2012 : Woods Hole Oceanographic Institution

New England is expected to experience a “moderate” regional “red tide” this spring and summer, report NOAA-funded scientists working in the Gulf of Maine to study the toxic algae that causes the bloom. The algae in the water pose no direct threat to human beings, however the toxins they produce can accumulate in filter-feeding organisms […]

Alarming Seal Die-off Prompts Federal Response

Scientists are on the water off the New England coast this week gathering evidence to determine what caused an unusually large spike in Harbor seal deaths. The carcasses showed no signs of starvation, which kills many young Harbor seals this time of year once they’ve weaned. Theories abound in the media, but evidence suggests that the seals could […]

2011 New England “Red Tide” Outlook and Management Response

In April 2011 scientists from the National Centers for Coastal Ocean Science-funded Gulf of Maine Toxicity (GOMTOX) project issued an outlook for a moderate regional bloom of the toxic alga, Alexandrium fundyense, that can cause ‘red tides’ in the spring and summer of this year, threatening the New England shellfish industry. However, there are signs […]

Gulf of Maine Harmful Algal Bloom Forecast Will Help Region Prepare

On February 24, researchers with the NOAA-funded Gulf of Maine Toxicity (GOMTOX) project will issue an advisory on the projected bloom of Alexandrium fundyense in the Gulf of Maine in 2010 at the Ocean Sciences meeting in Portland, Oregon. Although the algae pose no direct threat to human beings, toxins produced by this species can […]

New Research Aims to Unravel How Nutrients Drive Toxic “Brown Tides”

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, represented at NOAA by the National Centers for Coastal […]

Invasive Sea Squirts Threaten Shellfish Aquaculture

National Centers for Coastal Ocean Science researchers and their collaborators found that ten invasive tunicate species are fouling shellfish aquaculture operations along much of the U.S. East Coast, causing decreased growth rates, increased mortality, and high maintenance costs.  The survey identified the locations of highest fouling, which will be used to develop a plan to […]
