CSIRO O&A CTD Data Overview (1982 - present)

The CSIRO Oceans and Atmosphere (O&A) previously CSIRO Marine and Atmospheric Research (CMAR) CTD (Conductivity Temperature Depth) dataset includes data collected since 1982 during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. CTD data typically consists of vertical profiles binned at 2-metre intervals. Data usually includes conductivity, temperature, depth and salinity (derived), and may also include any or all of oxygen, fluorescence, optical back scatter (OBS), pH and transmittance. Individual metadata records have been created for each research voyage. The data is held in the O&A Information & Data Centre Data Warehouse, which currently holds over 14,321 CTD station records from more than 285 voyages.
