Frank Jennings, Jr., Glenn Research Center Engineers at NASA's Glenn Research Center in Cleveland are using NASA Glenn remote sensing technology, previously developed for Mars exploration, to learn more about the Lake Erie algal bloom that contaminated water supplies in northwestern Ohio and southeastern Michigan over the weekend. Deploying a hyper-spectral imager and miniature spectrometers aboard Glenn’s S-3 aircraft, which began the flight campaign on August 5, 2014, researchers...

Significant Harmful Algal Bloom In Western Lake Erie Predicted This Summer
2014-07-11 03:13:09

NOAA Headquarters NOAA and its research partners predict that western Lake Erie will have a significant bloom of cyanobacteria, a toxic blue-green algae, during the 2014 bloom season in late summer. However, the predicted bloom is expected to be smaller than last year's intense bloom, and considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake's western basin and are classified by an estimate of both its concentration and how far it spreads....

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...

Native Algae Species Is To Blame For 'Rock Snot' Blooms In Rivers Worldwide
2014-05-08 03:00:48

[ Watch The Video: ‘Rock Snot’ Blooms Due To Native Algae ] Dartmouth College Recent growths not caused by human introductions or emergence of new genetic strain The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed, a Dartmouth College-led study...

Reducing the size of the Lake Erie "dead zone" to acceptable levels will require cutting nutrient pollution nearly in half in coming decades, at a time when climate change is expected to make such reductions more difficult. That's one of the main conclusions of a comprehensive new study that documents recent trends in Lake Erie's health. It offers science-based guidance to policymakers seeking to reduce the size of toxic algae blooms and oxygen-starved regions called hypoxic zones, or dead...

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...

Rise In Toxic Algal Blooms Climate Change
2013-10-25 10:07:28

Brett Smith for redOrbit.com - Your Universe Online Algae is probably best known for the green scum it forms on top of stagnant water, and in addition to looking unpleasant, some algal blooms host strains of cyanobacteria that are highly toxic. According to a new study in the journal Science, nutrient enrichment and rising global temperatures are increasing the toxicity of some algal blooms in freshwater lakes, ponds and estuaries around the world. As these 'eutrophic' processes...

Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world’s seagrass meadows. Seagrass meadows, such as eelgrass or Halophila, grow along most of the world's coasts where they provide important habitats for a wide variety of life...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
