How Does Red Tide Knock Out Its Competition?
2014-06-05 03:05:40

By Brett Israel, Georgia Institute of Technology New research reveals how the algae behind red tide thoroughly disables – but doesn't kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem. Marine algae fight other species of algae for nutrients and light, and, ultimately, survival. The algae that cause red tides, the algal blooms that color blue ocean waters red, carry an arsenal of molecules that disable...

Toxic Algae Most Likely Cause Of Ancient Chilean Whale Strandings
2014-02-26 10:08:48

Brett Smith for redOrbit.com - Your Universe Online A site in the Atacama Desert of Northern Chile has become well known for its wealth of ancient marine mammal fossils, deposited there by a series of mass strandings. While the cause of whale or other mammal strandings that take place today can often be identified, the cause behind ancient strandings is much more difficult to pin down. According to a newly published report in the Proceedings of the Royal Society B, an international...

Massive Manatee Deaths In 2013 Attributed To Red Tide Algae
2013-10-31 15:40:37

Michael Harper for redOrbit.com - Your Universe Online According to the Florida Fish and Wildlife Research Institute in St. Petersburg, the number of manatee deaths in 2013 has already reached a record high of 769 fatalities and there are still two months left to go in the year. These deaths account for about 15 percent of the total population and specialists expect the number to go even higher before the year is out. Motor boats, long the greatest mortal enemy of manatees, aren’t to...

Robotic Sensor Tracks Toxic Red Tide
2013-05-08 09:53:09

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...

Research Now Allows Fishermen To Harvest Lucrative Shellfish On Georges Bank
2013-04-11 09:51:25

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...

Limited Phosphorus Makes Gulf Of Mexico Algae Even Meaner
2013-03-13 10:27:32

North Carolina State University When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North Carolina State University and the National Oceanic and Atmospheric Administration. The study shows that harmful and ubiquitous Karenia brevis algae, which cause red tide blooms across the Gulf of Mexico, become two to seven times more toxic when levels of...

'Red Tide' Species Deadlier Than First Thought
2012-07-25 15:15:43

redOrbit Staff & Wire Reports - Your Universe Online A researcher at the University of Connecticut and his team have discovered that a species of tiny aquatic organism prominent in harmful algal blooms sometimes called "red tide" is even deadlier than first thought, with potential consequences for entire marine food chains. Professor Hans Dam along with his research group in the school's Department of Marine Sciences have discovered that the plankton species Alexandrium tamarense...

Blue Light Culprit In Red Tide Blooms
2012-02-24 04:57:10

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment. "Previous theories about how...

Harmful algal blooms that affect seafood on the rise in California With toxic algal blooms – which can increase the amount of harmful toxins in the shellfish that California residents consume – ramping up in frequency and severity locally, scientists at USC have developed a new algae monitoring method in hopes of one day being able to predict when and where toxic "red tides" will occur. "We have, what we fear, is a hotspot here for some types of toxic algal blooms," said...

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...
