This dataset contains the processed Hydrology (HYD) data collected on Southern Surveyor voyage SS 02/92. The voyage took place in oceanic and shelf waters off south eastern Tasmania during 26 May - 18 June 1992. This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report (as available). Southern Surveyor 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, and nitrite.
