Case Study Gulf Of Main
In 2005, the most severe bloom of Alexandrium fundyense since 1972 spread along the New England coast. Scientists suspect that elevated rainfall and snowmelt in the spring, followed by two unusually late Nor'easters and increased runoff in May, fueled the outbreak by creating ideal conditions for algal growth.
This historic bloom extended from Maine to Massachusetts and resulted in extensive, and in some areas, unprecedented, closures to commercial and recreational shellfish harvesting to protect humans from PSP. State closures along the New England coast began as early as mid-May, disrupting shellfish sales during the busiest period of the tourist season. In Maine and Massachusetts alone, economic losses due to lost shellfish sales were estimated at $11 million.

A study from WHOI at Flamouth show that the confluance of prameter were there to give a significant algal bloom that spring of 2005, first highly seeded sea-bed in form of cyst more than 30% than the precedant year , high precipitation and snow melt and wih the runoff; a huge amount of nutriants had been druged to to the sea, all these ingrediants with favorable north eastern wind and inland marine curent to a huge Algal Bloom from the Bay of Fundy to Martha` Vignard.

in the aftermath of the 2005 HAB, NOAA through (ECOHAB) program, have funded a decade of research on Alexandrium in the Gulf of Maine, to increase understanding of bloom ecology. This research, coupled with research funded through the NOAA Monitoring and Event Response for Harmful Algal Blooms (MERHAB) program, has enhanced event response, forecasting, and mitigation capabilities for coastal managers.
For example, these programs have led to new methods based on molecular biology that are used to rapidly detect and map Alexandrium blooms. These data provide early warnings to coastal managers, and when combined with oceanographic and meteorological data from ships and moorings, can be used in recently developed biological and physical models. These models were used to forecast bloom movement and to understand the factors leading to the 2005 New England bloom event.
NOAA responded to the 2005 New England HAB by providing emergency funding for new and expanded sampling of the toxic algae in Massachusetts Bay. This emergency funding allowed monitoring of algae abundance and the extent and movement of the bloom. Researchers were also able to collect fish and zooplankton, to investigate the potential transfer of toxins via the food web and whale mortalities in the region. .
