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 […]

Ciguatera Fish Poisoning Predicted to Increase with Rising Ocean Temperatures

A new NOAA study, published in the journal Ecological Modeling, anticipates an increase in the incidence of ciguatera fish poisoning (CFP) in the Gulf of Mexico and the U.S. Southeast Atlantic coast with predicted rising global ocean temperatures due to climate change. Stable or slightly lower risks of CFP are forecasted for the Caribbean Sea. Researchers from […]

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 […]

2015 Harmful Algae Cyst Cruise: Student Blog

By Eric Gulledge, Ph.D. candidate at Jackson State University I am a NOAA-Environmental Cooperative Science Center fellow and currently enrolled in the Environmental Science Ph.D. program at Jackson State University. The NOAA-ECSC strives to train and develop student’s skills related to interdisciplinary science in support of coastal management. In keeping with NOAA’s mission, NOAA-ECSC afforded […]

‘Smartphone Microscopes’ Help Provide Early Warning of Harmful Algal Blooms in Lake Erie

Citizen scientists are using “smartphone microscopes” to identify harmful algal blooms in Lake Erie. The NCCOS Phytoplankton Monitoring Network, in collaboration with the U.S. Environmental Protection Agency, supplied volunteers in Western Lake Erie with the new generation of “smart” microscopes, which have built-in tablets. Each smartphone tablet is pre-loaded by NCCOS scientists with “Phyto”—an application that […]

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 […]
