Ocean Sciences Meeting Highlights Results of Sponsored Research

The 2014 Ocean Sciences Meeting showcased the reach and extent of research sponsored by NCCOS, including coral reefs, harmful algal blooms, hypoxia, applying research to management solutions, and integrated ecosystem assessments. NCCOS staff and sponsored research scientists gave over 25 oral and poster presentations and co-chaired a special session on mapping, monitoring, and managing mesophotic […]

Programmed Cell Death and the Decline of Harmful Algal Blooms

Programmed cell death, or self-induced cell mortality, is the subject of increasing attention and research efforts. All phytoplankton blooms decline for a variety of reasons—nutrient depletion, zooplankton grazing, virus infections, sedimentation—but programmed cell death as a means to bloom termination is a new concept, and one not well understood. Dr. Deana Erdner, an NCCOS-sponsored researcher […]

Ocean Acidification Promotes Disruptive and Harmful Algal Blooms on Our Coasts

The general decline in ocean pH (i.e., more acidic conditions) from the increasing concentrations of carbon dioxide (CO2) is well documented. Also well documented are increased nutrients entering coastal waters often promoting excessive and ecosystem disruptive algae blooms, including harmful algal blooms. The decay of these coastal blooms promotes bacterial respiration resulting in increased CO2, […]

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 […]

NCCOS Expertise Contributes to U.S. National Climate Assessment

Four NCCOS scientists wrote a NOAA technical report on “Oceans and Marine Resources in a Changing Climate” that led to a chapter in the Third National Climate Assessment (2013), produced by the U.S. Global Change Research Program. Carol Auer, Quay Dortch, Elizabeth Jewett, and Cary Lopez participated in this comprehensive review, wherein 63 experts examined […]

High Tech Sensors Used to Investigate Harmful Algal Bloom ‘Hot Spots’ in California

NCCOS scientists and their partners from the Monterey Bay Aquarium Research Institute (MBARI) are investigating the causes of Pseudo-nitzschia blooms and toxicity in Monterey Bay, Calif. from Sept. 5 to Oct. 10. Under the right conditions, some Pseudo-nitzschia produce domoic acid, a potent neurotoxin. Domoic acid accumulates in fish and shellfish, has caused bird and […]

California Red Tides and Other Algal Blooms Explained

The importance of algal blooms to the ecology of the ocean, including harmful red tides, is highlighted in a new “podcast” from the California nonprofit “Thank You Ocean Campaign.”  The podcast, entitled “Should We Fear Red tides?,” features Dr. Raphael Kudela from the University of California Santa Cruz. Dr. Kudela explains why harmful algal blooms […]

NCCOS Sponsors Harmful Algal Bloom Workshops for Upstate New York

New York’s borders encompass fresh, estuarine, and salt waters, each plagued by harmful algal bloom (HAB) outbreaks that pose risks to human health and the economic vitality of coastal communities. NCCOS is informing the upstate New York public and management community of the predicted rise of freshwater CyanoHABs by sponsoring workshops that provide information on a […]
