The Gulf of Maine Alexandrium catenella forecast was concluded on July 12, 2020. The forecast page is expected to be updated in Spring 2021.
Results here represent model solutions initiated from a cyst abundance map from October 2019, with germination, growth, and transport of Alexandrium catenella cells driven by the factors listed below. This model is a demonstration, and may not represent actual conditions in the Gulf of Maine.
cystmaptext =Fig.1. Abundance for top 1-cm sediment layer collected in October, 2019 (cells/cm2). Bold dots stand for the stations of cyst sampling, and light dots represent stations where cysts were extrapolated to. Crosses represent the location where routine shellfish toxicity was monitored during the bloom season. The cyst map was generated through extrapolation following Solow et al. (2014).
