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.

Pharmaceuticals in the Environment

The Pharmaceuticals in the Environment website is designed to provide available information for assessing risks to aquatic resources from drugs entering waterways from both point and non-point sources. The website includes information on frequently prescribed drugs as well as most antibiotics and lipid-lowering drugs.

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.

2000 years of sustainable use of watersheds and coral reefs in Pacific Islands: A review for Palau

In Palau and everywhere in the world, coastal coral reefs are threatened by sedimentation resulting from land clearing in the watersheds. Palau's largest island of Babeldaob is particularly susceptible to significant erosion due to its steep topography, high rainfall, and ...

A Baseline Chemical Contaminants Assessment of Sediment from the Nu’uuli Pala Lagoon, American Samoa

Thirteen marine sediment samples were collected as part of an effort to characterize and assess chemical contamination in the Nu’uuli Pala Lagoon on the island of Tutuila, American Samoa. Overall, concentrations of organic contaminants in sediment from the Nu’uuli Pala ...

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 coupled physical-biological model of the Northern Gulf of Mexico shelf: model description, validation and analysis of phytoplankton variability

The Texas-Louisiana shelf in the Northern Gulf of Mexico receives large inputs of nutrients and freshwater from the Mississippi/Atchafalaya River system. The nutrients stimulate high rates of primary production in the river plume, which contributes to the development of a ...

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 Manual of Previously Recorded Non-indigenous Invasive and Native Transplanted Animal Species of the Laurentian Great Lakes and Coastal United States

This manual presents geographic information by state of occurrence, and descriptions of the socio-economic impact created by the invasion of nonindigenous and native transplanted animal species in the Laurentian Great Lakes and the coastal waters of the United States. It ...

A modeling study of physical controls on hypoxia generation in the northern Gulf of Mexico

The Louisiana shelf (LA shelf) in the northern Gulf of Mexico experiences hypoxic conditions every summer due to the combination of eutrophication and strong water column stratification. Here we use a three-dimensional circulation model coupled with a simple oxygen model ...

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 ...
