File S1195Chl.csv This file contains chlorophyll-a profiles in 1 metre depth bins. Column A contains depth, annd the station numbers for each sample are given in Row 2, columns B-T. The sampling details for each station (date, time, latitude, longitude) are given in the headers of the CTD files, and again in the Hydrology files. At each station, a profile was made using the SeaTech fluorometer on the ctd, and samples taken for HPLC analysis of chlorophyll-a. Each profile was individually calibrated against the 6 chlorophylls taken on the cast.
