Measurements 
Physical oceanography 
Subsurface temperature and salinity measurementsQuantity: 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 - NQuantity: number of stations = 8
Description: Samples taken with the CTD/rosette sampler were processed and stored for total nitrogen
Other chemical oceanographic measurementsQuantity: 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 measurementsQuantity: number of stations = 8
Description: Samples taken with the CTD/rosette sampler were processed and stored for algal organic carbon
Contamination 
Suspended matterQuantity: number of stations = 8
Description: Samples taken with the CTD/rosette sampler were processed and stored for suspended solids
