Study Supports EPA to Control Both Nitrogen and Phosphorus in Freshwaters

One of the most common bloom-forming cyanobacteria (blue green algae) in freshwater ecosystems is Microcystis, which produces the liver toxin microcystin. Like many cyanobacteria, blooms of Microcystis are associated with higher temperatures and the availability of nitrogen (N) and phosphorus (P). Many freshwater ecosystems are P-limited, meaning P plays the key role in the occurrence of most cyanobacteria blooms, […]

National Coastal Ocean and Estuary Conference Provides Platform for NCCOS Research

The 23rd biennial Coasatal and Estuarine Research Federation Conference (CERF), held in Portland, Oregon this November, highlighted the scope of research sponsored by NCCOS including harmful algae and their toxins and ocean acidification and hypoxia (low dissolved oxygen) interactions. NCCOS exclusively hosted a major session and co-hosted a second major session with the NOAA Office of Oceanic […]

West Coast Harmful Algal Bloom Draws Attention of Congress

An ongoing toxic algal bloom off the U.S. West Coast was first detected in California in May 2015 and soon stretched to Alaska. Formed by the harmful algae Psuedo-nitzschia, this unusually long-lasting bloom is the largest bloom in the past 15 years. Record-setting concentrations of domoic acid, the neurotoxin produced by the bloom, have shut […]

Subsurface Algae Seeds Surface Harmful Algal Blooms in Southern California

Recently published findings from an NCCOS supported study in the central Southern California Bight indicate that harmful algal blooms (HABs) of Pseudo-nitzschia can develop offshore and below the surface prior to appearance near surface coastal waters. Surface blooms during the study period coincided with periods of upwelling or other processes that caused subsurface algal populations […]

Subsurface Algae Seeds Surface Harmful Algal Blooms in Southern California

Recently published findings from an NCCOS supported study in the central Southern California Bight indicate that harmful algal blooms (HABs) of Pseudo-nitzschia can develop offshore and below the surface prior to appearance near surface coastal waters. Surface blooms during the study period coincided with periods of upwelling or other processes that caused subsurface algal populations to move higher […]

Puget Sound Water Quality Review Highlights NCCOS HAB Research

The Puget Sound Ecosystem Monitoring Program released the 4th annual report on marine water conditions in Puget Sound for 2014 on September 9, 2015. The report, “Puget Sound Marine Waters: 2014 Overview,” enhances the understanding of the complex ecosystem of Puget Sound, an economic lifeline for Western Washington. The comprehensive report covers a host of […]

NCCOS Sponsors 20 New Research Projects

NCCOS awarded nearly $4.5 million in new research grants while maintaining sponsorship of 42 continuing projects during 2015 for a total of $8.2 million in funding for innovative research. All of the endeavors address significant and complex coastal issues. The projects were selected using a rigorous, competitive, and peer-review process. The cutting-edge research will provide critical […]

Toxic Algae and Their Seaweed Hosts May Predict Ciguatera Fish Poisoning

New research shows that different Caribbean species of Gambierdiscus—the microscopic marine algae most often associated with ciguatera fish poisoning (CFP)—demonstrate different growth and attachment behaviors with different coral reef seaweed hosts. The findings are helping researchers understand how ciguatoxin moves through the food web, information which, in turn, could be used to improve reef sampling and monitoring […]
