Chlorophyll a concentrations measured along the cruise track of AE1812 which transected from the Sargasso Sea to Coastal Rhode Island during May 2018.
In situ Chlorophyll a was measured at each station along the AE1812 cruise track. A CTD was deployed to collect water from the euphotic zone. Samples were filtered in triplicate onto GF/F and 5µm and 20µm polycarbonate filters.
Chl a was extracted from filters in 100% denatured ethanol for 12 hours, measured on a 10-AU Fluorometer, and chlorophyll a and phaeophytin concentrations were calculated based on a predetermined calibration curve. Concentrations on each filter were used to determine total chl a within each size fraction.
