Fixing the nearshore data-collecting sled

Detailed Description
In 1981, USGS researcher Abby Sallenger was working on development of a new data-acquisition system, “capable of measuring waves, currents, and the nearshore profile in breaking waves." The elaborate sled consisted of a mast, various winches, infrared rangefinder, and optical prisms mounted at the top of the mast. Apparently in this photo, a quick fix to the optical prisms was required, and Bruce Richmond was tasked with climbing up to make the adjustment. Bruce Jaffe holds the ladder in place.
