Storm Bay Bathymetry - 5m resolution (FRDC Project 2018/131)
High resolution bathymetry data was collected for Storm Bay, Tasmania as part of the FRDC project 2018-131 'Storm Bay Observing System: Assessing the Performance of Aquaculture Development. Objective 2: Provide a comprehensive map of benthic habitats and bathymetry of the Storm Bay region
and assessment of change at key focus areas'.
Data is supplied as a single Web Map Service of hillshaded bathymetry for the mapped region. Data is available for download as (1) bathymetry, and (2) hillshade tiff files.

- Statement
- Multibeam data were collected aboard the RV Noctiluca (IMAS/University of Tasmania) with a ENL WASSP F3 operating at a default operating frequency of 160 kHz. Motion was corrected with the inertial motion unit Advanced Navigation Spatial, with an accuracy of 0.1° for roll, pitch and yaw, and 5 cm or 5% of water depth for heave. Heading was provided by a Hemisphere V103 (accuracy: 0.3°). Geographic positioning was provided by a Fugro 9205 GNSS receiver (Trimble GA 810 antenna) augmented with differential positioning with the Marinestar G2 (GPS/GLONASS) system (in World Geodetic System 1984; WGS84). Bathymetric surfaces were created for each survey day within 32 subregions within Storm Bay (e.g., Day XX-Region X). GSF files were processed using QPS Qimera 2.1. Data were originally gridded at 2-m horizontal resolution in WGS84 UTM Zone 55S. Bathymetric data were corrected for sound velocity and tidal amplitude. Depths were corrected for tidal amplitude to the Lowest Astronomical Tide (LAT) based on high/low tidal predictions at the Hobart or Parsons Bay stations on survey days (see http://www.bom.gov.au/autralia/tides) and using the formula to derive tidal amplitudes at 1-min intervals: Di=D + [h1+(h2-h1)*cos(π*((t-t1)/(t2-t1 )+1))+1)/2] Where Di is corrected depth and D is measured depth, h1,2 correspond to the predicted heights of the high and low tides, t1,2 are the times of the high and low tides with t being each 1-min time step. Depths were subsequently corrected to Mean Sea Level (MSL) using the AusGeoid09 model, with LAT sitting 0.88 m below MSL in Storm Bay. The bathymetric surface was manually corrected for outliers and exported as a GeoTIFF. Bilinear interpolation was used to fill gaps, and the surface was smoothed with a low-pass filter using a 3x3 moving window to remove noise. The final gridded surface was generated by merging all grids using a bulk-shit approach, i.e., average discrepancy in depth (m) in areas of overlap, over consecutive days, using the earliest mosaic as reference. The final bathymetric grid is made available at a horizontal resolution of 5 m.
