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. {"type": "Polygon", "coordinates": [[[80.458, -57.25783], [191.38319, -57.25783], [191.38319, 12.25567], [80.458, 12.25567], [80.458, -57.25783]]]} 80.458 191.38319 -57.25783 12.25567 Data Link documentDigital AODN portal (Individual profile data only) HTML aodn:CTD_casts documentDigital CTD deployments WMS ctd documentDigital HTML Data Link documentDigital Data available from data TRAWLER HTML Documentation Link documentDigital This work is licensed under a Creative Commons Attribution 4.0 International License HTML Unnamed resource documentDigital License Graphic PNG
