Products

Maps, Tools & Applications

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.

Data & Publications

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, ...

Cruise Report: Spring 2006 Survey of Ecological Conditions of the U.S. Middle Atlantic Bight, NOAA Ship Nancy Foster NF-06-06-NCCOS

This cruise report is a summary of a field survey conducted in coastal-ocean waters of the Mid-Atlantic Bight from Nags Head, North Carolina to Cape Cod, Massachusetts and from approximately 1 nautical mile (nm) of shore seaward to the shelf ...

Cruise report: Spring 2007 survey of ecological conditions along the continental shelf off Florida from Anclote Key to West Palm Beach, NOAA ship Nancy Foster Cruise NF-07-08-NCCOS (May 15 - May 28, 2007)

This cruise report is a summary of a field survey conducted in coastal-ocean waters off Florida from Anclote Key to West Palm Beach and from approximately 1 nautical mile (nm) offshore seaward to the shelf break (100 m). The survey ...

Environmental toxicology data collected by the National Status and Trends Program for monitoring contaminants in coastal United States marine water bodies from 01 Jan 1960 to 05 May 2010 (NODC Accession 0074376)

The National Status and Trends Program is comprised of three nationwide programs: Benthic Surveillance, Mussel Watch, and Bioeffects. These programs are in place to observe estuarine and coastal waters nationwide to describe the current status and detect changes in the ...

Eurasian watermilfoil fitness loss and invasion potential following desiccation during simulated overland transport

Vegetative reproduction promotes human-mediated dispersal of aquatic invasive plants as fragments “hitchhike” between water bodies on boats and trailers. However, desiccation of plant fragments may also reduce fitness, decreasing the likelihood of fragment survival as transport distances increase. Current inter-lake ...

Great Lakes Mussel Watch: Assessment of Contaminants of Emerging Concern

The current report summarizes Great Lakes mussel tissue contaminants of emerging concern (CEC) data obtained between 2013-2015. The study design informs MWP management, stakeholders and general public about the frequency of occurrence, and the magnitude of CECs in mussels. We ...

Limitations of gravity models in predicting the spread of Eurasian watermilfoil

The effects of non-native invasive species are costly and environmentally damaging, and resources to slow their spread and reduce their effects are scarce. Models that accurately predict where new invasions will occur could guide the efficient allocation of resources to ...

Linking environmental conditions and ship movements to estimate invasive species transport across the global shipping network

Some nations, and the International Maritime Organization, are moving towards requirements for managing ballast water to reduce the number of alien species transported and released. These and other measures will be most efficient when targeted at ships posing the greatest ...

Molecular Response of the Bloom-Forming Cyanobacterium, Microcystis aeruginosa, to Phosphorus Limitation

Cyanobacteria blooms caused by species such as Microcystis have become commonplace in many freshwater ecosystems.
