Canadian and U.S. marine scientists have found a hot spot for toxic algal blooms is affecting the Washington and British Columbia coasts. Researchers from the National Oceanic and Atmospheric Administration, San Francisco State University and the universities of Washington, Maine and Western Ontario said the hot spot for the toxic harmful blooms is a part of the Strait of Juan de Fuca, which separates Washington state from Canada's British Columbia. The scientists said they determined that,...

A new study funded by NOAA and the National Science Foundation reveals that a part of the Strait of Juan de Fuca, which separates Washington state from Canada's British Columbia, is a potential "hot spot" for toxic harmful algal blooms affecting the Washington and British Columbia coasts. Understanding where and how these blooms originate and move is critical for accurate forecasts that could provide early warning to protect human and ecosystem health, according to NOAA scientists.Scientists...

U.S. and other scientists have linked nutrient pollution to an increase in the number of harmful algal blooms, sometimes called red tide, in coastal seas. When harmful algal blooms occur, they taint seafood with toxins, cause human respiratory and skin irritations and cause fish or mammal kills in coastal waters. The link to nutrient pollution, presented in 21 articles in the journal Harmful Algae, could elevate harmful algal blooms to the forefront of coastal management issues needing...

An international group of scientists is linking nutrient pollution in the world's coastal seas to an increase in the number of harmful algal blooms reported in recent years. When harmful algal blooms (HAB's) occur, they taint seafood with toxins, cause human respiratory and skin irritations and cause fish or mammal kills in coastal waters. In the December edition of the journal Harmful Algae, scientists present a compilation of 21 articles outlining the role of nutrient pollution in the...

By Reich, A Blackmore, C; Hopkins, R; Lazensky, R; Geib, K; Ngo- Seidel, E A "red tide" is a harmful algal bloom that occurs when toxic, microscopic algae in seawater proliferate to a higher-thannormal concentration (i.e., bloom), often discoloring the water red, brown, green, or yellow. Red tides can kill fish, birds, and marine mammals and cause illness in humans (1). Florida red tide is caused by the dinoflagellate Karenia brevis, which produces toxins called brevetoxins and is most...

By KEVIN MILLER; OF THE NEWS STAFF State health officials are urging lobster eaters to avoid the greenish innards known as the tomalley because of risks of shellfish poisoning. Health officials for years have advised against eating the tomalley, the lobster liver some regard as a delicacy. The Maine Center for Disease Control and Prevention reiterated its advisory Friday, however, after some lobster livers tested positive for high levels of toxins caused by large blooms of red tide algae....

By Kevin Miller, Bangor Daily News, Maine Jul. 18--State health and fisheries officials are urging lobster eaters to avoid the green, gooey innards known as the tomalley due to risks of shellfish poisoning. Health officials have for years advised against eating the tomalley, the lobster liver regarded as a delicacy by some. The Maine Center for Disease Control reiterated its advisory Friday, however, after some lobster livers tested positive for high levels of toxins caused by large...

By Jennifer Smith, Newsday, Melville, N.Y. Jul. 15--Clam harvests in the Great South Bay were in steep decline by the time brown tide arrived on Long Island in 1985, but this year's historically most widespread algae bloom has generated renewed concern and an unprecedented attempt to involve the federal government. Speaking yesterday at a Patchogue dock against a backdrop of water darkened by brown tide, Sen. Charles Schumer and Brookhaven Town Supervisor Brian Foley called on the...

Conditions are ripe for another large bloom in New England waters; weather and current patterns will determine outcomeThe end of April usually brings the first signs of harmful algae in New England waters, and this year, researchers from the Woods Hole Oceanographic Institution (WHOI) and North Carolina State University (NC State) are preparing for a potentially big bloom.A combination of abundant beds of algal seeds and excess winter precipitation have set the stage for a harmful algal bloom...

By Patrick Donohue, Destin Log, Fla. Dec. 5--What some call the worst outbreak of red tide near Destin in more than a decade may be on the way out. Water samples taken by the Florida Fish and Wildlife Conservation Commission last week, revealed that the highest concentration of K. brevis, the Florida red tide organism, in the area was on the west side of Destin's East Pass. That sample showed the algae in "low" concentrations. Water samples taken from Indian Bayou, White Point and...
