Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner Trilogy 7200-000 fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed at IOS in Room 2423 4 weeks after the cruise. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. Chlorophyll values ranged from 0.13-1.42 ug/l in 15 samples. 0 samples were below Minimum Limit of Detection (10% and 0 duplicate pairs had a CV>30%. Our average dataset %CV is 3.89% for 2013 - 2021 so the overall quality of this dataset is good. Minimum Limit of Detection (MLD): The stated MLD for the Turner Trilogy 7200-000 fluorometer is 0.025 ug/L for CHL-a. Samples below the MLD are reported as is and assigned Quality Flag 2 with an associated comment. Where samples are taken in duplicate and the average of the two is
