The objective of WAMSI DREDGING SCIENCE NODE Project 4.4 is to examine the suitability of automated in situ sediment deposition sensors based essentially on an upward facing nephelometer (see Ridd et al. 2001) to assess sediment deposition. Prototype versions of this device developed by Peter Ridd at James Cook University - have been deployed in situ and although the sensor currently gives useful information, the shape of the sensor needs to be optimized and the sensor readings need to be calibrated against settled sediment surface density as measured in units of mg cm2. The objective of Project 4.4, which is being led by Peter Ridd at James Cook University, is to re-design, optimise and calibrate the deposition sensor head to more closely mimic the trapping of sediments on a coral's surface. The project will determine how the new sensor geometry responds to turbidity events and deposition events in situ and in the laboratory caused by different particle size distributions under different turbulence regimes. Once working, the deposition sensor will be used in the laboratory experiments (WAMSI DREDGING SCIENCE NODE Project Project 4.6).
