Alexandrium cell counts from CTD bottle sampling from 2012 to 2019 in the Gulf of Maine
Standard station CTD profiles measurements (down casts) with water sampling (up casts);
Calculations of the concentration (cells/Liter) of Alexandrium catenella, formerly A. fundyense, were completed using MS Excel. The spreadsheet used inputs of the original volume sieved at sea (usually 2 Liters), the volume re-suspended into formalin and then methanol (usually 14ml), and the volume of the plankton concentrate filtered for the molecular probe assay (usually 7ml, or less volume if during a significant bloom), and the number of labeled cells observed on that filter.
