| Measurements | |
| Physical oceanography | |
| CTD stations | Quantity: number of stations = 27 Description: FSI mini-conductivity, temperature and depth profiler attached to plankton sampler. Profiles used to identify environmental parameters. |
| Subsurface temperature and salinity measurements | Quantity: number of stations = 9 Description: Samples of surface sea water collected for analysis onshore of conductivity/salinity |
| Biology and fisheries | |
| Zooplankton | Quantity: number of stations = 27 Description: 'Gulf VII - type' towed plankton sampler, deployed in a 'V' shaped profile from surface to near bottom and back to surface. Zooplankton and eggs/larvae collected using 270 um and 80 um mesh nets and preserved in formalin for analysis on shore. Volume of water filtered is calculated from data recorded by self-logging flowmeters. |
| Eggs and larvae | Quantity: number of stations = 27 Description: 'Gulf VII - type' towed plankton sampler, deployed in a 'V' shaped profile from surface to near bottom and back to surface. Zooplankton and eggs/larvae collected using 270 um and 80 um mesh nets and preserved in formalin for analysis on shore.
