16 ST | December 2018 www.sea-technology.com decisions on subsequent dives and data collection. This is an important process that future scientists can use to act and deliver on research with- in a 24-hr. period in quickly chang- ing environments. "In the future, if we can trust these algorithms enough, it should be possible to change traditional workflows and have robots inform each other of what they see in real time and make reliable decisions without the aid of a human in the loop," Thornton predicted. The ocean is changing over mul- tiple spatial and temporal scales. Oceanographers have many tools to study slow changes that take place in a single location but are limit- ed when trying to understand pro- cesses over large areas and at fast temporal resolution. This work with AUVs and ROVs to quickly map and analyze the seafloor will con- tribute to the toolset of techniques available to oceanographers that will allow them to address things they were not able to in the past. The work for Thornton and his team does not stop after leaving Falkor. Even with artificial intelligence doing work in the field, there are still many images that need more detailed analysis and interpretation to help achieve a deeper under- standing of the areas that were sur- veyed. The team will continue the work of analysis, likely with more expeditions in the future. A summary video of the August 2018 expedition can be viewed at youtu.be/C-3ZZiw8fd4.

The seafloor images were collected in less than 24 hr. of bottom time and processed while the team was still on site during the expedition.
