Mapping the deep ocean: Geoscience Australia and the search for MH370

Brief description

A short film describing the processes of bathymetric mapping and side scan sonar, used to gather data within the search area for missing Malaysia Airlines flight MH370. Synopsis: The film begins with a brief description of Geoscience Australia's role working with the lead agencies in the search process. It explains that existing satellite data is not detailed enough to assist in the search for MH370 and that more detailed bathymetric surveying is required before an underwater search can commence. The film describes how a bathymetric survey is carried out using sonar systems mounted on a ship's hull. It then shows imagery derived from the bathymetric mapping of the search area. The film then shows how a detailed underwater search is carried out, using the bathymetry as a guide. Animation shows how a towed, submersible vehicle gathers more detailed data while travelling slowly at a height of approximately 100 metres above the sea floor. The animation shows how side scan sonar reveals more detailed information about sea floor features. The film ends with a brief summary of the role of the Australian Government agencies involved in the search. Brief credits follow with a copyright statement and publication information. About the data visualisation: This video contains data visualisation and animation sequences. Bathymetry visualisations are derived from data gathered within the MH370 search area. Side scan sonar visualisations are derived from demonstration data only, not gathered within the MH370 search area. Animation sequences showing ship-mounted bathymetry and towed side-scan sonar are representations only and not to scale.
