NSW Environment Multi Beam Echo Sounder Gridded Data

Gridded multi-beam echousounder (MBES) bathymetry and backscatter data acquired using NSW Department of Planning Industry and Environment MBES systems aboard RV's Bombora, Seascan and Glaucus. Fieldwork surveys were completed as part of the SeabedNSW program funded by NSW government through Coastal Reforms (>2015), HabMap Program funded through Marine Parks Authority (now under Marine Estate Management Authority) or through collaborations with partner agencies or institutions. Surveys are predominantly on the open coast and within NSW state waters (2017) with Applanix Wavemaster POSMV (>2011) recording 3D motion in POSPac. Attitude and positional data were acquired in POSView and post processed using POSPac either Single-Base or Precise-Point-Positioning modules for improved vessel Smoothed Best Estimate of Trajectory. Data were cube modeled in Fledermaus/Qimera software (>2010) to IHO 1B standard and cleaned-soundings exported before being gridded using bin-weighted averaging (generally 5 m grid cell size) relative to Australian Height Datum and issued in grid coordinates (UTM WGS84 Zone55 or 56; GDA2020 Zone 55 or 56). General details on vessel setup, mobilisation and processing are provided at https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Research/Our-science-and-research/seabed-nsw-standard-operating-procedures-multibeam-surveying-190101.pdf with survey specific details in the Survey Report and DPIE Rigor Statement (can be provided upon request). Data packages provided via the Australian Oceanographic Data Network (https://portal.aodn.net.au) include bathymetry and backscatter in multiple formats; while those provided on AusSeabed (https://portal.ga.gov.au/persona/marine) are gridded bathymetry and backscatter data as geotif only. Data are not to be used for navigation purposes.
