Calibrated Fluorescence Profiles from the K-Axis Voyage of the Aurora Australis, 2016

Many stations were omitted from the calibration regression due to high variability between fluorometer and chlorophyll a measurements at that site. We do not know why this occurred - possibly a mismatch in depth measurements (e.g. caused by waves). The stations INCLUDED in the regression were: 7,8,9...

Description
Summary:Many stations were omitted from the calibration regression due to high variability between fluorometer and chlorophyll a measurements at that site. We do not know why this occurred - possibly a mismatch in depth measurements (e.g. caused by waves). The stations INCLUDED in the regression were: 7,8,9,11,15,17,28,31,32,33,37,39,40,41,42,44 Processed CTD instrument data - Corrected fluorescence profiles at the Southern Kerguelen Plateau, Indian Sector of the Southern Ocean. The fluorometer was calibrated through the regression of burst measurements against in situ chlorophyll a measured at the same depths and sites using high performance liquid chromatography (Wright et al. 2010). Zero chlorophyll a reference points were included in the regression and were obtained through averaging fluorometry data over 200-300 m bins. The resulting linear equation used to convert flourometry data was: chlorophyll = 0.262*fluorescence + 0.101. Column measurements (µg L-1) and integrated data (0-150 m, mg m-2) for each CTD station are provided.
