Abstract
<p>This resource contains multibeam backscatter data for Bynoe Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources) during the period between 3 and 27 May 2016 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. <p>The specific objectives of the survey were to: <p>1. Obtain high resolution geophysical (bathymetry) data for Bynoe Harbour; <p>2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for Bynoe Harbour; and <p>3. Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. <p>This dataset comprises multibeam backscatter data. A detailed account of the survey is provided in: Siwabessy, P.J.W., Smit, N., Atkinson, I., Dando, N., Harries, S., Howard, F.J.F., Li, J., Nicholas W.A., Picard, K., Radke, L.C., Tran, M., Williams, D. and Whiteway, T. 2016.

Lineage
The Bynoe Harbour Marine Survey 2016, GA-4452/SOL6432 was acquired by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and Department of Environment and Natural Resources (Northern Territory Government) onboard the RV Solander between 3 and 27 May 2016. The AIMS Cruise Leaders were Mr. David Williams (leg 1) and Mr. Simon Harries (leg 2), the NTGov Chief Investigator onboard was Dr. Neil Smit, and the GA Survey Leaders were Dr. Justy Siwabessy (leg 1) and Mr. Floyd Howard (leg 2). This dataset was acquired using Kongsberg's SIS acquistion software and processed onboard using CMST-GA MB Process v15.04.04.0 software by Justy Siwabessy, Kim Picard, Floyd Howard, Neil Smit, Dave Williams, Nick Dando, Ian Atkinson and Simon Harries.
