NOAA announces grants to predict ocean acidification’s effects on commercial fisheries

As scientists continue to research ways in which the oceans are changing – and what these changes mean for fish populations, three new research projects will receive funding to examine the effects of ocean acidification on fisheries, and the coastal economies that depend upon them. Ocean acidification occurs when the ocean absorbs carbon dioxide from […]

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 […]

Offshore wind farms will be encouraged in tracts along the East Coast – The Washington Post

The federal government is poised to auction to wind farm developers 2,434 square miles of the continental shelf in the Atlantic Ocean, which would allow wind farms to sprout 10 miles off the shores of six states, from Massachusetts to Virginia. Extensive efforts are underway to avoid the fiasco of the first proposed offshore wind […]

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 […]
