This data collection contains water column observations from CTD probes and water bottles deployed by the National Institute of Water and Atmospheric Research (NIWA) and its predecessor, the New Zealand Oceanographic Institute. A variety of instruments where used in this dataset, including: Sea-Bird SBE 911Plus CTD
This data collection contains observations from CTD sensors attached fisheries trawls deployed by the National Institute of Water and Atmospheric Research (NIWA) and funded by the Ministry of Primary Industries. Data was sourced from SeaBird MircoCAT SBE 37 instruments which were attached to the headlines of trawl nets as part of fisheries research programs. The data is processed using the SBE Data Processing software and only the downcast of the cast is retained (because of the turbulence of the water generated by the trawl gear once the trawl is underway. Measured variables are temperature, depth, and salinity. The sensors on the CTD are all regularly calibrated by the manufacturer, but data are not calibrated in-situ.
