Studying Carbon Dioxide Absorption In Antarctic Seas
Georgia Institute of Technology The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such...
Latest Algal bloom Stories
A new study on the feeding habits of ocean microbes calls into question the potential use of algal blooms to trap carbon dioxide and offset rising global levels. These blooms contain iron-eating microscopic phytoplankton that absorb C02 from the air through the process of photosynthesis and provide nutrients for marine life. But one type of phytoplankton, a diatom, is using more iron that it needs for photosynthesis and storing the extra in its silica skeletons and shells, according to an...
Success of Michigan lake restoration company offers hope to nutrient overloaded Colorado lakes and reservoirs. Fort Collins, Colorado (PRWEB) June 11, 2013 Oxygen deprived Colorado lakes and reservoirs are about to get desperately needed help in the fight against nutrient pollution, invasive weeds and seasonal algae growth. Building on scientifically proven results and a cost effective financial strategy, Michigan based Lake Savers LLC is expanding operations to include large fresh water...
GREAT GUANA CAY, Bahamas, June 3, 2013 /PRNewswire/ -- Acclaimed coral scientist Tom Goreau spoke about coral reef decline at Baker's Bay Club as a result of excessive fertilizer run-off. The speech, presented at the Bahamas National Natural History Conference in Nassau, was well received by the audience and is the first public presentation of data from the Baker's Bay coral reef controversy.

April Flowers for redOrbit.com - Your Universe Online The way scientists monitor and manage red tides or harmful algal blooms (HABs) in New England may be transformed by a new robotic sensor deployed in the Gulf of Maine coastal waters by Woods Hole Oceanographic Institution (WHOI). WHOI launched the new instrument at the end of last month and expects to deploy a second system later this spring. The robotic sensor will add critical data to weekly real-time forecasts of the New England...
BOWLING GREEN, Ohio, April 23, 2013 /PRNewswire/ -- Enhanced satellite imagery from Blue Water Satellite (http://www.bluewatersatellite.com/) of Bowling Green, Ohio, similar to what NASA has used on Mars missions, is being used as a powerful assessment tool for lake communities and organizations working to make near-term impact on the harmful algal bloom problems in our nation's water bodies. In Clear Lake California (located about 120 miles north of San Francisco and one of the...
Woods Hole Oceanographic Institution Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA’s Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX...
USGS Tiny sea creatures no bigger than a thumbtack are being credited for playing a key role in helping provide healthy habitats for many kinds of seafood, according to a new study by the Virginia Institute of Marine Science and U.S. Geological Survey. The little crustacean “grazers,” some resembling tiny shrimp, are critical in protecting seagrasses from overgrowth by algae, helping keep these aquatic havens healthy for native and economically important species. Crustaceans are...
University of Texas at Austin [ Watch the Video Copepod Nauplius Swimming at 10 Degrees C ] Olympic swimmers aren't the only ones who change their strokes to escape competitors. To escape from the jaws and claws of predators in cold, viscous water, marine copepods switch from a wave-like swimming stroke to big power strokes, a behavior that has now been revealed thanks to 3-D high-speed digital holography. Copepods are tiny crustaceans found in nearly every aquatic environment on...
redOrbit Staff & Wire Reports - Your Universe Online Instead of being an isolated occurrence, a record-breaking 2011 algae bloom in Lake Erie could be a harbinger of things to come, researchers report in this week's online early edition of the journal Proceedings of the National Academy of Sciences (PNAS). The hazardous algae bloom – the largest in the recorded history of Lake Erie – was likely caused by long-term changes to farming practices in combination with weather...
A European consortium develops a novel technology to monitor and control harmful algae blooms. ZOETERMEER, The Netherlands, March 14, 2013 /PRNewswire-iReach/ -- The patented LG Sonic MPC ensures fast and efficient algae control by combining online water quality monitoring, telemetering and ultrasonic technologies to provide the state-of-the-art treatment against algae and cyanobacteria in ponds, lakes and dams.
