This dataset contains oceanographic data collected at a coastal station off Evans Head, New South Wales (lat. 29 deg. 08 min. S, long. 153 deg. 38 min. E) between November 1952 and June 1969. Data were not collected for the period 1960-1965. The stations were set up under the CSIRO coastal monitoring programme in the 1950s and were sampled approximately monthly for temperature, salinity, dissolved oxygen, phosphate and nitrate. The data are stored on-line as part of the CMR hydrology archive in Hobart. Additional copies of the data are deposited with the NODC data archive (World Data Centre-A) in the U.S.A., and details of relevant data files can be viewed via their website by requesting the file inventory for this coastal station which is NODC platform code "09E2". Station details, plus printed versions of the data to 1960, have been published in CSIRO's "Oceanographical Station List" series.
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.
