| Measurements | |
| Physical oceanography | |
| Subsurface temperature and salinity measurements | Quantity: number of stations = 8 Description: CTD/rosette sampler deployed to aquire temperature and salinity data from the depth profile |
| Optics (eg underwater light levels) | Quantity: number of stations = 8 Description: CTD/rosette sampler deployed to aquire light data from the depth profile |
| Chemical oceanography | |
| Total - N | Quantity: number of stations = 8 Description: Samples taken with the CTD/rosette sampler were processed and stored for total nitrogen |
| Other chemical oceanographic measurements | Quantity: number of stations = 8 Description: Samples taken with the CTD/rosette sampler were processed and stored for nutrients. Samples were taken from the clean water supply for nutrient determination during surface mapping |
| Other chemical oceanographic measurements | Quantity: number of stations = 8 Description: Samples taken with the CTD/rosette sampler were processed and stored for algal organic carbon |
| Contamination | |
| Suspended matter | Quantity: number of stations = 8 Description: Samples taken with the CTD/rosette sampler were processed and stored for suspended solids |
| Biology and fisheries | |
| Primary productivity | Quantity: number of stations = 3 Description: Primary production assessments were carried out at these stations |
| Phytoplankton pigs (eg chlorophyll, fluorescence) | Quantity: number of stations = 8 Description: Samples taken with the CTD/rosette sampler were processed and stored for chlorophyll. Samples were taken from the clean water supply for chlorophyll determination during surface mapping |
