Eden Lassie - Buoy 1 - Quality (near realtime)

Ambient estuarine water quality monitoring data (includes near real-time sites)

Created 04/05/2025

Updated 20/05/2025

This resource collects time series water physicochemical In-situ parameter readings, water (current) flow velocity and direction, Nitrogen and Carbon compounds and weather conditions every ten minutes. Quality control codes have been introduced to the data to assist with interpretation of the data.

Equipment is housed in a large yellow floating Buoy, anchored in position within the tidal zone in Eden Lassie Creek upstream of the discharge for De Costa Auaculture property (in Sandfly Creek) approximately 5.0km from the mouth of the Eden Lassie Creek, Proserpine at Lat -20.1845 Long 148.411 Datum GDA.

Water column depth at this position is approximately 5.0 meters.

Water Quality is measured by a YSI EXO2 mulitparameter sonde at 0.4m below the surface, which collects :

  • Timestamp
  • Record
  • EXO_TempC
  • EXO_SpCondmScm
  • EXO_Salpsu
  • EXO_pHmV
  • EXO_pH
  • EXO_Depthm
  • EXO_BatV
  • EXO_ChlugL
  • EXO_ChlRFU
  • EXO_DOPerSat
  • EXO_DOmgL
  • EXO_BGAPERFU
  • EXO_BGAPEugL
  • EXO_TurbFNU
  • EXO_fDOMRFU
  • EXO_fDOMQSU
  • EXO_TurbNTU

Water flow direction and velocity are also collected at a depth of 1.0 meter below the surface via an Aanderra Doppler Current Sensors (DCS) Model 420 which operates on the backscatter acoustic doppler principle. The sensor has built-in compass and tilt sensor.
