This dataset contains the processed Hydrology (HYD) data collected on Franklin voyage FR 01/99. The voyage took place off the Queensland and Newsouth Wales coast between Brisbane and Newcastle during January and February 1999. This dataset currently exists as raw data only, and will be available from the CSIRO Marine and Atmospheric Research Data Centre in Hobart once processing has been completed. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report (as available). Franklin on-voyage hydrology data are typically obtained from water samples collected in Niskin bottles at various depths during each CTD cast. Parameters measured normally comprise temperature, salinity, dissolved oxygen, phosphate, nitrate, silicate, nitrite and ammonia.
