Summary of measurements |
- -Hydrology and geochemistry stations from surface to bottom - CTD measurements.
-Determining oxygen, freon, total carbon, nutrients, salinity, Ph and alkalinity concentrations - water samples taken at 30 levels at each station. -Direct measurements of currents using shipboard Doppler current meters (300 and 75 KHz); Current measured directly by Doppler current meter attached to CTD chassis. -Bathymetric surveys using EM12D multibeam echosounder along the hydrology leg and along the track in transit between 45S/9W and Capetown. -XBT along track in transit between 45S/9W and Capetown. -Ship's sensors: weather unit, temperature, surface salinity.
