I don’t show off the bay in August. Three summers ago a mat of green algae about three inches thick clung to the beach. I remember it vividly because I regularly run those trails in the summer and finish with a swim and a relaxing beach walk back to the trailhead. The algae, drying and turning brown, was as thick and nasty as week-old pudding.

The Chesapeake Bay Commission recently released a report concerning the feasibility of nutrient trading for the Bay.

The Environmental Protection Agency has awarded the Louisiana Coastal Protection and Restoration Authority (CPRA) $100,000 to reduce hypoxia in the Gulf of Mexico. This area in the northern Gulf of Mexico is known as the ‘dead zone.’ The funds will be used to develop a statewide nutrient reduction strategy for Louisiana which adopts strategic elements identified in action plans of the Gulf of Mexico Alliance and the Gulf of Mexico Hypoxia Task Force

MARTINSBURG - It was understood from the start that Martinsburg's sewer customers' rates would be going up because the city had been mandated to make significant improvements to its treatment plant as part of the Chesapeake Bay cleanup program.

High-resolution aerial photographs taken by professor Kim Reece of the Virginia Institute of Marine Science show the broad extent of the algal blooms or “red tides” currently discoloring lower Chesapeake Bay.

The red tides are back. The massive annual blooms of harmful algae that cloud the Chesapeake Bay, local waterways and shorelines every summer have been spotted floating from the lower Bay as far north as the Rappahannock River, according to the Virginia Institute of Marine Science in Gloucester Point.

The 1972 federal Clean Water Act, which this year marks the 40th year since its enactment after a veto by President Richard Nixon, steadily improved how cities and industries managed wastewater. The blooms largely disappeared for more than three decades. Now they are back, and in many places worse than ever. Blue green algae mar the waters of Lake Superior near the Apostle Islands National Lakeshore. The western shoreline of Lake Michigan, from Kewaunee, Wisconsin, to Sturgeon Bay is an almost unbroken green runway of algae, in some places about a foot thick. Last summer, Lake Erie experienced the worst blue-green algae bloom in decades. And while, so far, Platte Bay is mostly clear of algae this summer, little ghostly green tendrils float in the water, like jellyfish. They brush against your arms as if to say, “Remember us. We’re still around.

Charter boat captains are helping the state monitor water quality and watch for harmful algae blooms in Lake Erie's western basin between Toledo and Sandusky

udubon is fighting three permits that allow growers south of Lake Okeechobee to pump phosphorus-laden water toward the Everglades

Ontario is investing in innovative solutions to help protect Great Lakes water quality. The Keswick Water Pollution Control Plant is testing an advanced oxidation process to reduce the amount of phosphorus and micropollutants such as pharmaceuticals and personal care products entering Lake Simcoe. Phosphorus is the key pollutant threatening the environmental health of Lake Simcoe

(NOAA) supported scientists have found the size of this year’s Gulf of Mexico oxygen-free ‘dead zone’ to be the fourth-smallest since mapping of the annual hypoxic, or oxygen-free area began in 1985. Measuring approximately 2,889 sqmi, the 2012 area is slightly larger than Delawar

- An algal bloom off the west coast of Ireland is responsible for significant fish and shellfish kills from Galway to Donegal, according to the Marine Institute.

On the way back from Canada about two weeks ago, I noticed bright yellow-green particulate in Lake Erie. This was right about the time that a harmful algae bloom was reported at certain beaches in Lake County.

The Sea Scouts have been studying the water quality of Lake Erie, in particular the toxic blue-green algae blooms. They have been looking into simple ways to help provide remedies

A study published in the current issue of the journal Nature says that fertilization of the ocean with iron compounds has induced algae blooms that are accompanied by considerable CO2 drawdown in the ocean surface layer.

YORKTOWN, Va. — Researchers in Virginia are keeping an eye on red algae blooms in the Chesapeake Bay. The blooms suck oxygen from the water. That makes it difficult for marine life to survive. They are driven by warm water and excessive nutrients, and typically occur in the lower Chesapeake Bay in July or August.

HERMANN, Mo. – The Missouri River stretches more than a quarter-mile from shore to shore here, its muddy water the color of coffee with a shot of cream.

The Karenia mikimotoi algae bloom that has been affecting areas of the North West from Mayo to Donegal, and at lower concentrations down along the rest of the West coast, continues to impact on coastal marine life in several areas and has shown some signs of increase, according to the Marine Institute.
