Harmful Algal Bloom Intensity May be Tied to Ocean Carbon Dioxide Levels

Recent findings show that increases in oceanic carbon dioxidefrom the burning of fossil fuels over the last 200 years may have increased the intensity and toxicity of Karenia brevis blooms. Researchers from the National Centers for Coastal Ocean Science (NCCOS) report that this effect is projected to increase substantially by the turn of the century with […]

Working to Reduce Toxic Blue-Green Algal Blooms in Chesapeake Bay

NCCOS-sponsored researchers recently explored several promising techniques to mitigate toxic cyanobacteria (blue-green algae) blooms in the Chesapeake Bay region. The team focused on sediment-flocculation, in which local sediments and commercial clays are combined with the flocculating compound chitosan to sink and bury Microcystis cyanobacteria blooms. Other techniques evaluated included post-bloom flushing and early spring deployment of […]

NCCOS Research Featured in EPA Webinar Series on Inland Harmful Algal Blooms

On Jan. 14, NCCOS researchers Steve Morton and Rick Stumpf were featured speakers at an Environmental Protection Agency (EPA) webinar focused on inland harmful algal blooms. The event was part of an EPA webinar series intended to build awareness about the effects of nutrient pollution and harmful algal blooms on the environment. Dr. Morton provided […]

Bacteria Isolate Degrades Harmful Algal Toxins in Drinking Water

Cyanobacterial harmful algal blooms (“cyanoHABs”) occur worldwide—causing detrimental effects to ecosystems and local economies—and can produce toxins that pose threats to human health and limit potable water supplies. Microcystis and other genera of cyanobacteria produce a compound known as Microcystin-LR (MCLR) that is toxic to the liver and inhibits nerve functions, muscle activity, and cellular metabolism. […]

NCCOS Research in Today’s Rapidly Changing Global Environment

Two national science conferences recently highlighted NCCOS research: The theme at the 7th Symposium on Harmful Algae in the United States (Oct. 27–31, 2013; Sarasota, FL) was harmful algal blooms (HABs) in a changing world, especially a more acidic one. NCCOS HAB scientists and sponsored researchers  organized, advised,  chaired sessions, and presented some 13 oral […]

Addressing the Decline of Michigan’s Saginaw Bay

NCCOS-funded scientists participated in a recent forum held by the Michigan House Democrats’ Great Lakes and Conservation Task Force to address human-caused stresses to Lake Huron’s Saginaw Bay. The team presented findings and recommendations related to phosphorus inputs and eutrophication symptoms that are adversely affecting the bay’s fisheries and water quality. The NCCOS-funded team is […]

NCCOS Research Underpins International Lake Erie Ecosystem Report

With Lake Erie threatened again by eutrophication and harmful algal blooms, the Great Lakes International Joint Commission (IJC) recently established a “Lake Erie Ecosystem Priority” (LEEP) initiative to provide advice to governments to develop policy and implement management approaches to restore the lake’s ecosystem. The IJC released the LEEP report on August 29, 2013 for […]

NCCOS Research Results Impact International Policy

On September 10, 2013, NCCOS-sponsored researcher Dr. Don Scavia will be a panelist at the Great Lakes Triennial Meeting focusing on Lake Erie. This forum is designed to inform and engage the public regarding the new Lake Erie Ecosystem Priority (LEEP) study report that was commissioned by the International Joint Commission (IJC) in 2012 to […]
