Description:
The methods of data collection, processing, and assessment of the quality of the results ofa survey conducted at the Southern Ionian Sea off the Messinian Peninsula, Greece are presented.Data were collected by the GEBCO-Nippon Foundation Alumni Team, competing in the Shell OceanDiscovery XPRIZE, during the Final Round of the competition. Data acquisition was conductedby the means of unmanned vehicles only. The mapping system was composed of a single deepwater AUV (Autonomous Underwater Vehicle), equipped with a high-resolution synthetic aperturesonar HISAS 1032 and multibeam echosounder EM 2040, partnered with a USV (Unmanned SurfaceVessel). The USV provided positioning data as well as mapping the seafloor from the surface, usinga hull-mounted multibeam echosounder EM 304. Bathymetry and imagery data were collected for24 h and then processed for 48 h, with the extensive use of cloud technology and automatic dataprocessing. Finally, all datasets were combined to generate a 5-m resolution bathymetric surface, as an example of the deep-water mapping capabilities of the unmanned vehicles’ cooperation andtheir sensors’ integration.
