Maps, Tools & Applications
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 biogeographic assessment of the Channel Islands National Marine Sanctuary: A review of boundary expansion concepts for NOAA's National Marine Sanctuary Program
This biogeographic assessment represents the continuation of an ongoing partnership between the National Marine Sanctuary Program (NMSP) and the National Centers for Coastal Ocean Science (NCCOS). The purpose of this collaboration is to provide sanctuary managers with basic information on ...
A Biogeographic Assessment off North/Central California: In Support of the National Marine Sanctuaries of Cordell Bank, Gulf of the Farallones and Monterey Bay. Phase II Environmental Setting and Update to Marine Birds and Mammals
This document is Phase II of a biogeographic assessment completed in 2004, described below. In the spring of 2001, NOAA's National Marine Sanctuary Program (NMSP) and National Centers for Coastal Ocean Science (NCCOS) launched a project to assess biogeographic patterns ...
A comparison of seafloor habitats and associated benthic fauna in areas open and closed to bottom trawling along the central California continental shelf
A number of studies have shown that mobile, bottom-contact fishing gear (such as otter trawls) can alter seafloor habitats and associated biota. Considerably less is known about the recovery of these resources following such disturbances, though this information is critical ...
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, ...
An Economic Analysis of Shipping Costs Related to Potential Measures to Manage the Co-Occurrence of Maritime Vessel Traffic and Whales in the Channel Islands Region
This report provides findings from an analysis and evaluation of the economic effects of potential measures to manage the co-occurrence of shipping traffic and whales in the Channel Islands region off the coast of California. These potential management measures are ...
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 ...
Benthic Characterization of Deep-Water Habitat in the Newly Expanded Areas of Cordell Bank and Greater Farallones National Marine Sanctuaries
A large area of the seafloor off northern California lies within the US National Marine Sanctuary System, but very little of the habitat has been explored and even less is characterized using visual survey techniques, especially deep-water habitats. Benthic surveys ...
