After the test run was complete, Autosub continued with its primary mapping mission, using multibeam sonar to produce an extremely detailed map of the seabed. We’ve only completed a small part of the total area we’re hoping to cover, but you can already see in the image below how the resolution of the new map compares to the map we made previously using ship-based multibeam acoustics.

As you can imagine we spent much of the day going through the catalogue of data that was collected in just five hours of seafloor mapping. There was lots of gathering around computer screens.
Autosub’s next mission is planned for tomorrow, the aim of which will be to continue bathymetric mapping a bit more of the study area before we start with the large-scale photographic surveys of the benthic megafauna and fish.
