At the forward end of the main lab is an intimidating array of seventeen screens with a chair at which the scientist on watch sits – and watches. If all is well, nothing much happens. On one screen the magnetometer readings flicker and change, on another the multibeam echo-sounder record creeps slowly upwards, while above it a silvery triangle indicates the reliability of the multibeam record. Up to the left, coloured balls float around on a screen showing the satellites that we are using for navigation, while two video screens show the winch drum and the after deck and are used during dredging. In front of these are the controls for the winch, used by Josh or Jim at critical times during dredging. And in overall charge is the computer technician, Mary Huey, who moved into computers after giving up a career in university teaching of ancient English. The watching scientist writes entries in the log every half hour and makes sure that all is working well. If not, he or she can call up Mary or the Bridge for help.
