Baffle Creek 2021 (Current velocity and direction)

Baffle Creek water quality monitoring data - Historical

Created 24/02/2025

Updated 24/02/2025

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 10 minutes.

Equipment is housed in a large yellow floating buoy, anchored in position within the tidal zone at the Ferry Crossing approximately 16km from the mouth of Baffle Creek, between Gladstone and Bundaberg.

Lat: -24.50861, Lon: 151.9279, Datum: GDA

Water flow direction and velocity are 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.

Doppler parameters measured/collected are:

  • ABSSpd-Avg
  • AbsTilt-Avg
  • Direction-Avg
  • EastCur-Avg
  • Heading-Avg
  • LoggerBattV
  • LoggerPanelTemp
  • MaxTilt-Avg
  • NorthCur-Avg
  • PingCnt-Avg
  • SigStrength-Avg
  • SPstd-Avg
  • StdTilt-Avg
  • TiltX-Avg
  • TiltY-Avg

A Gill MaxiMet weather station provides the following parameters:

  • Gill-DewPoint-Avg
  • Gill-Latitude
  • Gill-Longitude
  • Gill-Pressure
  • Gill-Rain-mm-Tot
  • Gill-RH
  • Gill-SRad-Avg
  • Gill-SunHours-Avg
  • Gill-Temperature-Avg
  • Gill-Time
  • Gill-TotalDailyRain-mm
  • Gill-TotalRain-mm
  • Gill-Wd-StdDev
  • Gill-WindSpd-Max
  • Gill-Ws-Mean

A Trios "Opus" spectrophotometer with 10mm optical path, submerged at 1 meter below the surface, measures Nitrogen and Carbon compounds, such as:

  • OPUS1-MeasureTime
  • OPUS1000-N-NO3
  • OPUS1004-CODeq
  • OPUS1014-TOCeq
  • OPUS1016-TSSeq
  • OPUS1032-SAC254
  • OPUS1034-Abs360
  • OPUS1036-Abs210
  • OPUS1038-FitError
  • OPUS1042-Abs254
  • OPUS1052-COD-SACeq
  • OPUS1060-SQI
