Maps, Tools & Applications

In the Data Collection you will find data, maps, imagery and selected publications from the 2003 and 2007 phases of the Main Hawaiian Islands Benthic Habitat Mapping project.
Project PageView Product

A benthic habitat map of coral reef ecosystems around Majuro, an atoll in the Republic of the Marshall Islands was developed. The maps were created from satellite images and depict coral reefs, seagrass, sand, reef flats, and other ecosystem features in the shallow waters of the atoll. Benthic maps are foundational tools for monitoring, conservation, development planning, stock assessments and other management actions.

We developed benthic habitat maps for shallow (<30 meters) areas around the main islands of the Republic of Palau to help local managers and researchers develop reef fish management strategies, optimize biological monitoring sampling design, and develop place-based action strategies to address key issues and remedy specific threats to coral reefs. Project PageView Product

The first effort in this location, we mapped the waters surrounding Palmyra Atoll to help researchers develop reef fish management strategies, optimize biological monitoring sampling design, and evaluate natural and man-made changes over time (e.g., climate change, invasive species eradication, and lagoon causeway mitigation).

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.

BIOMappers let you interactively view data, aerial imagery, dive photography, underwater video and related publications developed for the benthic habitat mapping of many U.S. coral reefs. In addition to viewing benthic habitat data, you can examine the attributes of the data and show different thematic representations. Photos and videos taken during dive missions are linked to the location of the dives.

This Data Explorer Map contains datasets including marine environment, benthic habitats, fishes, sea turtles, marine mammals and seabirds off the Main Hawaiian Islands. This work supports the Bureau of Ocean Energy Management's (BOEM) review of lease requests for renewable energy projects in federal waters, to minimize potential impacts to the ecosystem. This assessment is part of a larger process by BOEM and State of Hawaii to evaluate renewable energy proposals offshore of MHI.

Access deep sea coral and sponge data: Digital Map allows for search, discovery, and download of the National Deep-Sea Corals and Sponges Database. All points are categorized and colored by common vernacular categories. Users can search by taxon, region, time, and depth. Data downloads can be initiated using the search parameters on the map and the on-screen geographic extent.

Contributing PartnersNOAA’s Deep Sea Coral Research and Technology Program (DSCRTP) and its partners.

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.

A comparison of seafloor habitats and associated benthic fauna in areas open and closed to bottom trawling along the central California continental shelf

A comprehensive investigation of mesophotic coral ecosystems in the Hawaiian Archipelago

Although the existence of coral-reef habitats at depths to 165 m in tropical regions has been known for decades, the richness, diversity, and ecological importance of mesophotic coral ecosystems (MCEs) has only recently become widely acknowledged. During an interdisciplinary effort ...

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 guinea pig's tale: learning to review end-to-end marine ecosystem models for management applications

A shift towards ecosystem-based management in recent decades has led to new analytical tools such as end-to-end marine ecosystem models. End-to-end models are complex and typically simulate full ecosystems from oceanography to foodwebs and fisheries, operate on a spatial framework, ...
