Southern Ocean Chlorophyll-a, pigment and optical data from Aurora Australis AA 1997/98 V6

Updated: 2023-02-01

This record contains data collected at 15 stations on the Aurora Australis AA06/97 cruise, known as the SNARK cruise. Water samples were generally collected along a transect around 142degE from 42-55degS to determine the bio-optical characteristics of the region. Parameters measured are the concentration of chlorophyll and carotenoid pigments and the absorption coefficient for dissolved (CDOM) particulate (a/p) and detrital (a/d) components of the water column. In addition to the station samples 106 water samples were collected from the output of the underway fluorometer and analysed for chlorophyll and carotenoid pigments only. The BSI six-channel radiometer was deployed ot station.
