Summary of Field Work: |
The objective is to determine whether the structure from motion technique is a viable high-resolution method on the seafloor using ROVs and assess the accuracy compared to ocean bottom pressure measurements.
We will use the ROV Trident to take photographs and make ocean bottom pressure measurements on a seafloor monument. The camera on the ROV will be used to take video or series of photographs, which will allow us to reconstruct a 3D model (structure from motion) and measure the dimensions of the benchmarks. A mobile seafloor pressure recorder (MPR) will be used to make pressure measurements at the benchmarks for 30-minute periods. These measurements will serve as a validation for vertical measurements from the 3D structure from motion model. |
|
Summary of Facility Requirements: |
We anticipate the use of the ROV Trident and a USBL or DVL and ranging system for locating our site; a concrete seafloor benchmark (supplied by our lab) and use of the A-frame for deployment; a mobile ocean bottom pressure recorder (supplied by our lab), and power and communications to the ROV; and two GPS antenna (supplied by our lab), deck space for setup, and a data stream to ship navigation |
