Microorganisms duke it out within algal blooms
2016-03-02 07:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: An unseen war rages between the ocean's tiniest organisms, and it has significant implications for understanding the ocean's role in climate change, according to a new study. David Needham and Jed Fuhrman from the USC Dornsife College of Letters, Arts and Sciences sampled water off the coast of Southern California over the course of five months, almost every day shortly after an algal bloom occurred, and found that the cloud of microorganisms is anything but uniform. Instead, they found traces...

Rising lake temperatures may worsen algae blooms
2015-12-22 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Some of the worlds biggest temperature jumps are happening in lakes suggesting that problems such as algae blooms and low-oxygen zones hazardous to fish will get worse, a new report says. An analysis of 235 lakes that together hold more than half of the Earths fresh surface water found they have been warming an average of 0.61 degrees per decade, the report said. While seemingly insignificant, the increase is bigger than changes recorded in the oceans or the atmosphere. Such rapid swings can...

Harmful algal blooms and water quality
2015-12-22 13:00:00| LifeSciencesWorld
[NEWS] Harmful algal blooms (HABs) occur naturally, but their outbreaks are influenced by climate change and droughts, nutrient enrichment and manmade factors, such as contaminants from sewage and stormwater discharge, natural resource extraction or agricultural runoff, to name a few. When an outbreak occurs, it causes restrictions on fisheries, recreation and drinking water, and it can have significant economic consequences. In developed countries, HABs cause more severe acute environmental…

World's Lakes At Risk Of Continued Algal Blooms Triggered By Warm Waters
2015-12-21 04:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The Earth's lakes may take a devastating hit from climate change, researchers report in a new study. Rapidly warming waters in freshwater bodies, including several Great Lakes and many reservoirs, trigger harmful algae blooms that ultimately threaten freshwater supplies for local ecosystems. A team of researchers led by Catherine O'Reilly from Illinois State University analyzed satellite temperature data and long-term ground measurements taken from a total of 235 lakes, which store half of our...

'Unprecedented' Toxic Algal Blooms Harming West Coast's Wildlife
2015-12-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Weather: While algal blooms are relatively common, this one is different. The algae thriving off the West Coast, Pseudo nizchia, can produce a deadly neurotoxin called domoic acid. What's more, the bloom was unusually large and lasted an unusually long duration, partially due to warm water conditions brought in by El Nio. Now, scientists are warning of the widespread effects the toxic algae is having on wildlife and the seafood industry. "The duration of the bloom and the intensity of the toxicity were...
