The Huon Estuary Study was undertaken by CSIRO Marine Research between 1996 and 1998. The Huon Estuary is in South Eastern Tasmania. This record references the autonomous profilers which were deployed as part of the Huon Estuary Study. The profilers operated at two locations, Killala and Hideaway Bays. At both sites conductivity, temperature, fluorescence, underwater light, dissolved oxygen and par sensors were deployed as well as a wind sensor at Killala Bay. For a number of parameters the raw data was processed using calibration co-efficients and converted to engineering units. The processed profile data is stored as daily, monthly and also as a dataset for duration of the deployment.
