| Measurements | |
| Physical oceanography | |
| CTD stations | Quantity: number of stations = 49 Description: FSI mini-CTD attached to sampler frame to provide profile of conductivity, temperature and depth. Purpose to monitor/ provide information on environmental paramaters. |
| Subsurface temperature and salinity measurements | Quantity: number of stations = 16 Description: Samples of sea water from surface/nr surface collected during selected tows. Analysed ashore for conductivity to compare to CTD measurements. |
| Biology and fisheries | |
| Zooplankton | Quantity: number of stations = 49 Description: Samples collected using Gulf VII plankton sampler, towed from surface to near bottom in 'V' shaped profile. Volume of water filtered calculated from self-logging flow meters inside nose cone. Eggs and larvae collected in 270um mesh net and preserved in formalin for later analysis. Purpose of analysis - to identify and quantify eggs and larvae. |
