4 . The system of claim 1 , wherein the plurality of lines connecting the camera assembly to the buoyant support connects a first end of the buoyant support to a first end of a frame of the camera assembly and a second end of the buoyant support to a second end of the frame.
5 . The system of claim 1 , wherein the camera assembly comprises a stereo camera, wherein the stereo camera has a first field of vision and a second field of vision perpendicular relative to the first field of vision.
6 . The system of claim 1 , comprising an inertial measurement unit or a fin coupled to a frame of the camera assembly.
7 . The system of claim 1 , comprising a power source and an electrical cord coupling the camera assembly to the power source.
8 . The system of claim 1 , wherein the camera assembly is communicatively coupled to a controller, the controller configured to operate the camera assembly.
9 . The system of claim 1 , wherein the buoyant support comprises a support frame and a floating device coupled to the support frame wherein the buoyant support comprises a fin coupled to the support frame.
10 . The system of claim 1 , wherein the plurality of lines connecting the camera assembly to the buoyant support comprise:
a first line connecting the buoyant support to a first corner of the camera assembly;
a second line connecting the buoyant support to a second corner of the camera assembly, wherein the second corner is different from the first corner;
a third line connecting the buoyant support to a third corner of the camera assembly, wherein the third corner is different from the first corner and the second corner; and
a fourth line connecting the buoyant support to a fourth corner of the camera assembly, wherein the fourth corner is different from each of the first corner, the second corner, and the third corner.
11 . The system of claim 1 , wherein the camera assembly comprises a frame, wherein the frame includes a set of weights that resist at least one of rotation or translation relative to the direction of travel.
12 . A floating camera assembly, the assembly comprising:
a frame having a first end and a second end opposite the first end;
a camera mounted to the first end of the frame;
a buoyant support carrying the frame and configured for suspending the frame and the camera under water; and
wherein the frame is connected to the buoyant support by a plurality of lines that are manipulable to raise or lower a portion of the frame to adjust an orientation of the camera when the camera is submerged under water.
13 . The assembly of claim 12 , comprising a second camera mounted to the second end of the frame.
14 . The assembly of claim 12 , comprising a coupling mechanism connecting the frame in parallel with the buoyant support when the frame is submerged under water, wherein the coupling mechanism includes the plurality of lines that are manipulable to raise or lower the portion of the frame to adjust the orientation of the camera when the camera is submerged under water.
15 . The assembly of claim 12 , comprising a damper coupled to the frame to resist rotation of the frame.
16 . The assembly of claim 12 , comprising a means for adjusting the orientation of the camera assembly, the means for adjusting being coupled to the camera assembly.
17 . A method of operating an underwater camera assembly, the method comprising:
submerging a camera assembly underwater, the camera assembly configured to scan a seabed while submerged under water and moving in a direction of travel;
positioning the camera assembly at a depth under water using a buoyant support, wherein the buoyant support is coupled to the camera assembly by a plurality of lines connecting the camera assembly to the buoyant support that are manipulable to raise or lower a portion of the camera assembly to adjust an orientation of the camera assembly; and
maintaining, using the plurality of lines connecting the camera assembly to the buoyant support, the orientation of the camera assembly corresponding to the direction of travel.
18 . The method of claim 17 , comprising adjusting the orientation of the camera assembly, wherein adjusting the orientation of the camera assembly comprises manipulating the plurality of lines connecting the camera assembly to the buoyant support to raise or lower the portion of the camera assembly.
19 . The method of claim 17 , comprising controlling the camera assembly using a remotely operated controller, the controller communicatively coupled to one or more cameras of the camera assembly.
20 . The method of claim 17 , comprising scanning the seabed using a stereo camera comprising a first field of vision and a second field of vision different than the first field of vision, wherein scanning the seabed comprises scanning using a second camera comprising a third field of vision different than the first field of vision and the second field of vision of the stereo camera.
