Researchers from WHOI and North Carolina State University are preparing for a potentially big bloom of harmful algae in New England waters this spring. A combination of abundant beds of algal seeds and excess winter precipitation have set the stage for an Alexandrium bloom similar to the historic “red tide” of 2005. Weather patterns and ocean conditions over the next few months will determine whether this year’s algal growth affects coastal shellfishing.Read More
Through the use of an automated, underwater cell analyzer developed at WHOI, researchers and coastal managers were recently able to detect a bloom of harmful marine algae in the Gulf of Mexico and prevent human consumption of tainted shellfish.Read More

The historic bloom of toxic algae that blanketed New England’s waters and halted shellfishing from Maine to Martha’s Vineyard in the spring of 2005 is over. But scientists are now wondering if there will be an encore.
Before departing, the algae likely left behind a colonizing population that may promote blooms in southern New England for at least the next few years.
Coastal resource managers shut down shellfish beds in three New England states in mid-May—including rare closures of Massachusetts Bay and Cape Cod Bay—because of an intense bloom of the toxic algae Alexandrium fundyense. Researchers from the Woods Hole Oceanographic Institution saw the ‘red tide’ coming before its toxic effects reached the shore.Read More

Researchers from Woods Hole Oceanographic Institution, the Marine Biological Laboratory (MBL), and the Massachusetts Institute of Technology (MIT) have embarked on a novel collaboration to investigate harmful algal blooms, ocean-borne pathogens, and potential pharmaceuticals from marine sources.Read More
Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse
both biologically and physically. The diversity and the high
energy of the ecosystem make estuaries remarkably resilient.
With a better understanding of these systems, we can reverse
their decline and restore the ecological richness of these
valuable, albeit muddy, environments.
The most widespread, chronic environmental problem in the coastal ocean is caused by an excess of chemical nutrients. Over the past century, a wide range of human activities—the intensification of agriculture, waste disposal, coastal development, and fossil fuel use—has substantially increased the discharge of nitrogen, phosphorus, and other nutrients into the environment. These nutrients are moved around by streams, rivers, groundwater, sewage outfalls, and the atmosphere and eventually end up in the ocean.Read More
Harmful algal blooms are natural and they are not new. But ocean scientists are growing concerned that they are now all too common. The unprecedented growth of human activities in coastal watersheds—including agriculture, aquaculture, industry, housing, and recreation—has drastically increased the amount of fertilizer flowing into coastal waters and fueled unwanted algal growth.Read More
