Aurora Australis Southern Ocean oceanographic (CTD) data, cruise au9206 (FISHOG)

Stations 83-93: residuals a bit lower than surrounding stations: data uncertainty may be slightly increased. Stations 103-111: no bottle samples; conductivity calibration from surrounding stations applied; accuracy therefore unknown. Stations 112-168: significant increase in data scatter; accuracy approximately 0.010 (PSS78).

The bottle data file contains salinities and nutrients. Dissolved oxygen data exist only as titration values recorded on the laboratory analysis sheets. The nutrient data show a fair amount of scatter, particularly when looking at the nitrate vs phosphate ratios.

These data should be used with caution. Measurement and data processing techniques are described, and a summary of the data are presented in graphical and tabular form.
