Products

Maps, Tools & Applications

Cyanobacteria Algal Bloom from Satellite in Albemarle and Pamlico Sounds, NC

NCCOS developed the Algal Bloom Monitoring System to routinely deliver near real-time products for use in locating, monitoring and quantifying algal blooms in coastal and lake regions of the US. This application delivers a suite of bloom detection products in the form of geographic based images. At this time products are available for selected regions. New products are being evaluated, and new regions are being considered; as they are proven useful, they will be made available through this system.

Harmful Algal Bloom Monitoring System

Harmful algal blooms (HABs), sometimes known as "red tide", occur when certain kinds of algae grow very quickly, forming patches, or "blooms", in the water. These blooms can emit powerful toxins which endanger human and animal health. NCCOS conducts and funds research that helps communities protect the public and combat blooms in cost-effective ways, and we are breaking new ground in the science of stopping blooms before they occur.

Phytoplankton Monitoring Network

NCCOS runs the Phytoplankton Monitoring Network (PMN) to link volunteers who monitor for marine phytoplankton and HABs in cooperation with professional scientists. We build a more informed public while expanding the reach and resolution of HAB monitoring. Over 200 PMN volunteers sample 140+ sites in 17 states and the US Virgin Islands.

Data & Publications

A Bayesian Semiparametric Regression Model for Joint Analysis of Microbiome Data

The successional dynamics of microbial communities are influenced by the synergistic interactions of physical and biological factors. In our motivating data, ocean microbiome samples were collected from the Santa Cruz Municipal Wharf, Monterey Bay at multiple time points and then ...

A changing nutrient regime in the Gulf of Maine

Recent oceanographic observations and a retrospective analysis of nutrients and hydrography over the past five decades have revealed that the principal source of nutrients to the Gulf of Maine, the deep, nutrient-rich continental slope waters that enter at depth through ...

A decade and a half of Pseudo-nitzschia spp. and domoic acid along the coast of southern California

Blooms of the marine diatom genus Pseudo-nitzschia that produce the neurotoxin domoic acid have been documented with regularity along the coast of southern California since 2003, with the occurrence of the toxin in shellfish tissue predating information on domoic acid ...

A high-resolution pre-operational forecast model of circulation on the Texas-Louisiana continental shelf and slope

A new pre-operational model of circulation over the Texas-Louisiana continental shelf and slope, based on the Regional Ocean Modelling System (ROMS) is presented. The model is designed with a number of practical applications in mind: to predict oil spill trajectories, ...

A Novel Antibody-Based Biomarker for Chronic Algal Toxin Exposure and Sub-Acute Neurotoxicity

The neurotoxic amino acid, domoic acid (DA), is naturally produced by marine phytoplankton and presents a significant threat to the health of marine mammals, seabirds and humans via transfer of the toxin through the foodweb. In humans, acute exposure causes ...

A quantitative real-time PCR assay for the identification and enumeration of Alexandrium cysts in marine sediments

Harmful algal blooms (HABs) are a global problem that affects both human and ecosystem health. One of the most serious and widespread HAB poisoning syndromes is paralytic shellfish poisoning, commonly caused by Alexandrium spp. dinoflagellates. Like many toxic dinoflagellates, Alexandrium ...

An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions

A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in ...

Asynchronous vertical migration and bimodal distribution of motile phytoplankton

Some motile phytoplankton have the capability to exploit deep sources of nutrients in a vertical migration cycle: photosynthesis in the near-surface layer, transit to depth, uptake of the limiting nutrient and transit back to the surface layer. If all four ...
