Latest Algal bloom Stories
WASHINGTON, April 7, 2015 /PRNewswire-USNewswire/ -- NASA has joined forces with the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and U.S.
Water-borne algal blooms from farm fertilizer runoff can destroy aquatic life and clog rivers and lakes, but scientists will report today that they are working on a way to clean up these environmental scourges and turn them into useful products. The algae could serve as a feedstock for biofuels, and the feedstock leftovers could be recycled back into farm soil nutrients.
Understanding how viruses attack giant algal blooms may help us understand their role in fixing global carbon.
The sea-grass beds of Long Island’s Great South Bay once teemed with shellfish. Clams, scallops and oysters filtered nutrients from the water and flushed money through the local economy. But three decades after the algae that cause brown tides first appeared here, much of the sea grass and the bounty it used to provide is gone.
The green stuff that clouds up fish tanks – it’s not just an aesthetic annoyance. In fact, if you’ve been watching recent news of algal bloom concerns in Lake Erie, you know that the right conditions for algae can lead to contamination of local water sources, potentially impacting aquatic life and humans.
Engineers 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.
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.
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.
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
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.
