Dennis Johnsey at Sea.  Johnsey was an old salt when I joined the Michelson.  He had already served on the Bowditch and was doing a second TAGS tour on the Mickey Maru.  Here we catch Dennis actually working--he's sitting at the plot table in NIC, one of the other OcUnit spaces in which we stood 24-hour watches at sea.  Behind and to the right of Dennis' head is NAVDAC, the CP677 computer running the Ocean Survey Program navigation software.  In the right foreground, out of focus, is a WPN-3 Loran-C receiver.  These receivers were, until recently, installed in Survey Control, another of the OcUnit work spaces, on the 03 Level abaft the Pilot House.
