Abstract

Chlorophyll a concentrations from addition incubation experiments performed aboard AE1812 while transecting from the Sargasso Sea to Coastal Rhode Island in May 2018.

Chlorophyll a was measured at the conclusion of each incubation experiment conducted in triplicate on AE1812. Samples were taken from biological replicates and filtered onto GF/F, 20 µm, 5µm 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.
