FK180731 #Adaptive Robotics (Go to data)

Wrap-up and wrap-up closing blog entry.

Overview of data collected during the expedition

Results of 3D photogrammetric reconstruction of the Southern Hydrates Ridge (depth 780m) that was generated by the AUV Ae2000f and Tuna-Sand. The mapped area shown in the poster covers 11.8 ha at an average resolution of 6 mm and is the largest known expanse of seafloor that has been visually mapped in colour. Outputs of an unsupervised classifier were used to analyse the imagery between deployments and generated information summaries such as the image class tree-map. The detailed views show a white bacterial mat that was identified by the classifier, which was subsequently surveyed by the AUV Tuna-sand at sub-millimeter resolution to gather more detailed information. The arrows illustrates the direction from which the isometric view of the reconstructions.

Sesoko - monitoring coral reefs off the coast of Okinawa (Go to data)

Our team has been gathering seafloor 3D reconstructions of mesophotic coral off of Sesoko island - off Okinawa in a collaborative effort with the Harii Lab the Ryukyu University, IIS University of Tokyo, ACFR University of Sydney and the Kyushu Institute of Technology. Currently, we have a 3-year temporal datasets of overlapping imagery collected using the AUV Tuna-Sand and Tuna-Sand 2, that is made available on Squidle+ for image annotation. Our observation in 2018 took place days after a direct hit from Typhoon Trami (Paeng), a Category 5 super typhoon with wind speeds of 195km/h. We hope our efforts will document the damage and the recovery as we continue to focus our efforts on this site.
