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 changing nutrient regime in the Gulf of Maine

Recent oceanographic observations and a retrospective analysis of nutrients and hydrography over the past five decades have revealed that the principal source of nutrients to the Gulf of Maine, the deep, nutrient-rich continental slope waters that enter at depth through ...

A quantitative real-time PCR assay for the identification and enumeration of Alexandrium cysts in marine sediments

Harmful algal blooms (HABs) are a global problem that affects both human and ecosystem health. One of the most serious and widespread HAB poisoning syndromes is paralytic shellfish poisoning, commonly caused by Alexandrium spp. dinoflagellates. Like many toxic dinoflagellates, Alexandrium ...

Asynchronous vertical migration and bimodal distribution of motile phytoplankton

Some motile phytoplankton have the capability to exploit deep sources of nutrients in a vertical migration cycle: photosynthesis in the near-surface layer, transit to depth, uptake of the limiting nutrient and transit back to the surface layer. If all four ...

Bloom dynamics of the red tide dinoflagellate Alexandrium fundyense in the Gulf of Maine: a synthesis and progress towards a forecasting capability

Paralytic shellfish poisoning (PSP) is a recurrent and widespread problem in the Gulf of Maine (GOM) caused by the dinoflagellate Alexandrium fundyense. Blooms of this species have been the subject of more than a decade of investigation through the ECOHAB-GOM ...

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 ...

Does the fall phytoplankton bloom control recruitment of Georges Bank haddock, Melanogrammus aeglefinus, through parental condition?

In 2003, the Georges Bank stock of haddock (Melanogrammus aeglefinus) experienced the largest recruitment event recorded during its assessed history. Several hypotheses have been advanced to explain recruitment variability in this much-scrutinized stock, including variability in the retention of eggs ...
