Maps, Tools & Applications

Experimental Gulf of Maine Alexandrium catenella Nowcast/Forecast Simulation

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.

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.

Detecting copepod grazing on low-concentration populations of Alexandrium fundyense using PCR

Zooplankton grazing is often a significant loss term for phytoplankton populations, including harmful algae, impacting the development and decline of blooms. However, detecting and quantifying predation on phytoplankton is often challenging, particularly during early bloom stages when phytoplankton cell concentrations ...

Diversity and dynamics of a widespread bloom of the toxic dinoflagellate Alexandrium fundyense

Historically, cosmopolitan phytoplankton species were presumed to represent largely unstructured populations. However, the recent development of molecular tools to examine genetic diversity have revealed differences in phytoplankton taxa across geographic scales and provided insight into the physiology and ecology of ...
