New studies demonstrate potential increases in waterborne toxins and microbes A panel of scientists speaking today at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled new research and models demonstrating how climate change could increase exposure and risk of human illness originating from ocean, coastal and Great Lakes ecosystems, with some studies projecting impacts to be felt within 30 years. "With 2010 the wettest year on record and third...

US scientists, speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington Saturday, said climate change could increase exposure to water-borne diseases originating in the world's oceans, lakes and coastal ecosystems, adding that the impact will most likely be felt within the next 30 years, and as early as the next 10 years. Numerous studies have shown that shifts from climate change make ocean and freshwater ecosystems more susceptible to...

(Ivanhoe Newswire) "“ Blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants, and human health. Previously, human activities were thought to be responsible for producing these impacts. Researchers looked into blue-green algae and their effects on zebrafish. They discovered the algae may add a new harmful element into the way they understand and...

Our growing reliance on coastal waters for food, trade and tourism means that these delicate ecosystems need to be more closely monitored to guarantee their future sustainability. ESA's CoastColour project is helping scientists develop techniques to take full advantage of the unique capabilities of the Medium Resolution Imaging Spectrometer (MERIS) sensor on its Envisat satellite. With a resolution of 300 m, MERIS provides the sharpest view of coastal waters to date, and includes spectral...

The quest to cure a terrible form of food poisoning caused by population explosions of algae that stain the water red and produce a potent toxin is the topic of a new episode in the American Chemical Society (ACS) Prized Science video series. Entitled "Taming the Red Tides," the high-definition video, released today, focuses on Michael Crimmins, Ph.D., winner of the 2010 Ernest Guenther Award in the Chemistry of Natural Products. Crimmins, a chemist at the University of North Carolina in...

Seed population portends a large regional bloom; impacts will depend on ocean conditions and weather Today, scientists from the NOAA-funded Gulf of Maine Toxicity (GOMTOX) project issued an outlook for a significant regional bloom of a toxic alga that can cause 'red tides' in the spring and summer of this year, potentially threatening the New England shellfish industry. An abundant seed population in bottom sediments has set the stage for a significant bloom of the toxic alga Alexandrium...

Predicting harmful algal blooms, or HABs, in the Great Lakes is now a reality as NOAA announces an experimental HAB forecast system in Lake Erie. HABs produce toxins that may pose a significant risk to human and animal health through water recreation and may form scum that are unsightly and odorous to beach visitors, impacting the coastal economy. Forecasts depicting current and future locations of blooms, as well as intensity, will alert scientists and managers to possible threats to the...

U.S. scientists say they have conducted the first remote detection below the ocean's surface of a harmful algal species and its toxin. Researchers at the National Oceanic and Atmospheric Administration's National Centers for Coastal Ocean Science and the Monterey Bay Aquarium Research Institute said their achievement represents a significant milestone in the effort to monitor the type and toxicity of harmful algal blooms. A robotic instrument owned by the aquarium -- a fully-functional...

Toxic bloom expected to be smaller than last year, but still significant The potential for an outbreak of the phenomenon commonly called "red tide" is expected to be "moderately large" this spring and summer, according to researchers with the Woods Hole Oceanographic Institution (WHOI) and North Carolina State University (NCSU). This advisory is based in part on a regional seafloor survey of quantities of Alexandrium fundyense "” the algae notorious for producing a toxin that...

A municipality official said on Tuesday that beaches in the Gulf tourism hub of Dubai have been plagued by a bloom of algae known as the "red tide" that has killed fish and is potentially harmful to humans. "This is a natural fauna that goes into harmful algal bloom," said Mohammed Abdulrahman Hassan, head of the marine and wildlife section in the municipality's environment office. Hassan said that the algae can cause skin and eye irritations as well as respiratory problems for people, who...
