CSIRO O&A Hydrology Data Overview (1942 - present)

The CMAR Hydrology data set includes data collected since 1942 during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels and coastal stations. Hydrology data usually consists of salinity and nutrient values obtained by analysing water samples taken at several depths at each station. The data may include temperature for some depths, nutrients may include any or all of ammonia, nitrite, phosphate, nitrate, silicate, oxygen. Individual metadata records have been created for each research voyage. The data is held in the CMAR Data Warehouse, which currently holds over 45,000 Hydrology station records from more than 500 voyages.
