This dataset contains the Hydrology (HYD) data collected on Soela voyage SO 3/89. The voyage took place in waters off the east coast of Tasmania during 14 April - 8 May 1989. This dataset currently exists as raw data only, since processing was not required at the time of collection. Additional information regarding this dataset is contained in the cruise report for this voyage. Soela on-voyage hydrology data are typically obtained from water samples collected in Niskin bottles at various depths. Parameters measured normally comprise temperature, salinity, dissolved oxygen, phosphate, nitrate, silicate, and nitrite.
