Diagram of the SQUID-5 towed surface vehicle and the waterproof camera housings with labeled components. The camera mounting mechanism aligns the camera axially with the dome and allows the camera to be adjusted fore and aft to accommodate various lens types and enable alignment with the glass port radius of curvature for minimal distortion.

Marine engineering technician Pete Dal Ferro sets up a newly acquired, portable, single-beam echo sounder on the San Lorenzo River in Santa Cruz, California. The new device, called CEESCOPE, collects bathymetric (depth) data and also records features of the subsurface.
