Marine, NOAA Officials Warn Local Officials on Threat of Dead Seals

It’s been almost a year since 150 young harbor seals died unexpectedly and washed up beaches in New Hampshire, southern Maine and northern Massachusetts. The New England Aquarium has taken this sad anniversary as an opportunity to share information with Seacoast communities about the cause of the deaths, ongoing monitoring efforts and to notify towns […]

Algal Bloom Species with Two Deadly Toxins Could Disrupt Marine Food Web | UConn Today

When tiny aquatic organisms reproduce in large amounts, algal blooms occur that take over portions of open water up to hundreds of miles in area. And when these oceanic plankton happen to be the toxic kind, they can be deadly to other living things crossing their path. One of the most poisonous and abundant of […]

Researchers discover that red tide species is deadlier than first thought – Phys.org

A University of Connecticut researcher and his team have discovered that a species of tiny aquatic organism prominent in harmful algal blooms sometimes called “red tide” is even deadlier than first thought, with potential consequences for entire marine food chains. Professor Hans Dam and his research group in the school’s Department of Marine Sciences have […]

New England Red Tide’s Defenses Influence Bloom Duration

In a new paper, researchers funded by the National Centers for Coastal Ocean Science discovered that the New England red tide species called Alexandrium releases a variety of compounds to kill its predators and lengthen bloom duration. In this case, the substance they use for defense is not the potent neurotoxin that accumulates in shellfish […]

Research Promotes Method to Slow the Spread of Encrusting Invasive Species

Dredging channels and cleaning boat hulls or fishing gear in or near established Didemnum colonies can create fragments of these invasive organisms that survive in the water column up to four weeks, disperse long distances, and even reproduce before resettling, possibly in new areas, according to NOAA research. The article suggests that cleaning equipment on land and reducing bottom disturbance […]

Device may help forecast outbreaks of red tide – Boston.com

Bruce Keafer calls it a robot in a box. Roughly the size of a kitchen sink, it was lowered into the waters off Portsmouth, N.H., last week, where it will sample marine organisms to measure toxic red tide cells over the next 45 days. The device, he hopes, will be a tool for forecasting outbreaks […]

Sensor Monitors Gulf of Maine Algae for Signs of Approaching Red Tides

During the week of April 26, researchers funded by the National Centers for Coastal Ocean Science deployed a sensor that detects cells of the species of algae responsible for toxic red tides in the Gulf of Maine. The device relays its data back to scientists on land to enable state agencies decide whether or not […]
