This dataset is part of the Gippsland Marine Environmental Monitoring (GMEM) project. The GMEM was developed in response to stakeholder concerns from the fisheries industry about a Geoscience Australia seismic survey in the Gippsland Basin (GA352 in April 2015), in addition to a broader need to acquire baseline data to be used to quantify impacts of seismic operations on marine organisms. A component of this study was to acquire images of the seafloor before and after the seismic survey for analysis of potential impacts of seismic operations on scallops. This dataset contains information collected from the AUV-Gavia on survey GA-350 conducted 27 March 3 April 2015. The Gavia is an AUV operated by the Australian Maritime College and includes a single camera and a range of environmental sensors. It was flown at an altitude of XX m at ~ 1.5 m/s with XX megapixel images acquired every XX seconds using a XX lighting system (the latter functional for Stations XX , XX, XX). In addition, Go-Pro cameras were mounted on the AUV's exterior to provide continuous video of the seafloor. The Gavia returned usable still images at 9 sites. This dataset contains the following data types: 1) Geotiffs acquired from the AUV nose cone camera with associated broadcale assessment of image quality on each transect, 2) Go-Pro videos acquired from external AUV mount, 3) optical backscatter, 4) ADCP data, 5) interferometric bathymetry, 6) associated shapefiles and location maps. For each data type, a Word file provides additional data about the folder structure, file types, and post-processing if applicable.
