3D Mona Rift Model

A recent study from the U.S. Geological Survey offers a workflow for generating virtual maps of the deep seafloor from archived exploration dives. This work can help advance exploration of the deep-sea frontier and extends into other fields. 

In this study, coauthors Claudia Flores and Dr. Uri ten Brink demonstrate innovative thinking for modeling the seafloor, as well as reliable troubleshooting research practices in this field. 

To develop this workflow, two remotely operated vehicles (ROVs) collected underwater images of the Mona Rift seafloor, located northwest of Puerto Rico. The approach placed emphasis on human-data interaction to overcome the quality of captured footage. Adjusting components of the ROV and video apparatus addressed the challenges that occur when taking videos of the seafloor at depths larger than 1,000 meters, such as poor navigation and inconsistent lighting, color attenuation and distortion, and camera orientation with respect to the vehicle. Using their workflow, archived footage can be processed and modeled in three months.
