Brief description
3D plume mapping was conducted over a 10day period at Chevron's Wheatstone dredging operation near Onslow Western Australia. Dredge plums created by a cutter suction dredge were sampled from CSIRO vessel RV Linnaeus on voyage number LI2013_v25. Underway measurements were made using a ship mounted ADCP to measure vertical velocity profiles and backscatter intensity and DALEC that measured the spectral qualities of incoming and reflected sea surface light. Profile data were collected using LISST (particle size distributions), CTD (backscatter, temperature and salinity), Hydroscat, Hydrorad (used measure light profiles, extinction coefficients , and scattering properties). Surface and bottom water samples were be collected at selected sites and analyzed for particle size distributionsLineage
