Measurements 
Physical oceanography 
CTD stationsQuantity: number of stations = 27
Description: Studies of microbial ecology by flow cytometry. Quantification of the planktonic community in terms of distributon, population and size structure of specific nano- and picoplankton groups and cyanobacteria, phytoplankton activity in the mixed layer, mortality of phytoplankton due to microzooplankton grazing and the partitioning of grazing by different size classes of microzooplankton. 3 types of grazing experiment conducted during the cruise - 9 experiments in total. CTD casts sampled for phytoplankton community structure with abundances at 20 m. Samples were collected at all available depths from the shallow biogeochemistry casts.
Optics (eg underwater light levels)Quantity: number of stations = 22
Description: Optical measurements made using the two aft telescopic cranes to take an optical profile simultaneously with measurements above surface to obtain the water leaving radiance. Satlantic light meters were profiled to a depth of 200m. Biospherics MER1010 Spectroradiometer was suspended at a height of 5 m above the sea surface to measure water leaving radiance at 12 wavelengths spanning the SeaWiFS range. A 'deck cell' measured downwelling sunlight intensity at four wavelengths in order to correct both the Spectroradiometer and the Satlantic data for changes in ambient light intensity during the measurements. Spectral data was collected from the spectroradiometer to characterize the sky colour so that the previous water leaving radiance data could be corrected for reflected skylight.
Optics (eg underwater light levels)Quantity: number of profiles = 22
Description: Optical profiles from 21 of the 22 casts. 21 spectral reflectance plots produced from each. Water samples taken from 22 optical casts. 5 water leaving radiance spectra were taken with the MARS whist underway for subsequent comparison with similar measurements made on the Thomas G Thompson.
