This record describes multibeam echosounder data collected on RV Linnaeus voyage LI2019_V01, 'Ningaloo Deepwater Reefs Hydrographic Survey' which departed Hillary's Boat Harbour, Perth, WA on the 15th March 2019 and concluded at Coral Bay, WA on the 29th March 2019. The Kongsberg EM2040c multibeam echosounder (single transceiver) was used to acquire seafloor bathymetry and backscatter information (and watercolumn backscatter) offshores of Ningaloo Reef, WA. Transit data to and from nightly anchorages has also been recorded. The EM2040c provides a 1.3° by 1.3° transmit and receive angular resolution respectively (single transceiver). The echosounder's nominal frequency range was 200 kHz and it was operated in dual swath mode. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 140 files totalling 32.5 GB of raw .all data, and 103 files totalling 178 GB of raw .wcd in the dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. Tide corrections were applied to the processed data in Caris using a GPS Tide based on the Applanix PosMV and Marinestar G4+ Ellipsoidal ht and thereafter reduced to AHD (Australian Height Datum) using a AusGeoid09 model. Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request. The raw data is offline but is available on request.

This dataset contains the Underway (UWY) data collected on Linnaeus voyage LI2015_V11. The voyage took place on the 7 May 2015 from Hillarys Boat Harbour (WA) to Rottnest Island and back to Hillarys (WA) on the 7 May 2015. Voyage Objectives: Servicing the Rottnest Island National Reference Station. There were no CTD deployments undertaken during the voyage. Fluorometer sensor data were not collected on this voyage due to sensor fouling from the previous voyage. Water depth data and TSG data were not collected on this voyage.

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 distributions
