Maps, Tools & Applications

NOAA mapped the shallow-water (less than 25 meters deep) coral reef ecosystems of the Florida Keys to support research, conservation, and management activities of state and federal agencies, including the Florida Keys National Marine Sanctuary and NOAA’s Coral Reef Conservation Program.

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.

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.

The Sampling Design Tool for ArcGIS randomly selects people, animals, objects, or places in a GIS environment to infer status or change. The tool was developed to create and implement a sampling design based on randomized sampling and test different sampling designs to see which is most precise and least costly.

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 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 topological approach for quantitative comparisons of ocean model fields to satellite ocean color data

In an effort to more fully employ underutilized satellite observations in ocean modeling, this work demonstrates a method for quantifying the agreement between time-evolving spatial features evident in fields of differing, but functionally related, variables that are more commonly compared ...

Assessing biophysical controls on Gulf of Mexico hypoxia through probabilistic modeling

A mechanistic model was developed to predict midsummer bottom-water dissolved oxygen (BWDO) concentration and hypoxic area on the Louisiana shelf of the northern Gulf of Mexico, USA (1985–2011). Because of its parsimonious formulation, the model possesses many of the benefits ...
