Figure 1. Part of the housing assembly procedure: installing o-ring* seals on an end cap. *Rubber o-rings are often used to seal undersea housings. Properly installed in correctly machined grooves, they can withstand enormous pressures for many years. --Photo by Geoff Cram

Figure 2: Larry Nielson installing underwater connectors* onto an end cap. *Underwater connectors allow signals and electric power to pass between the equipment on the shore and the housing through the big connector at the back, as well as between the housing and the instruments through the smaller connectors. The grey and gold caps on two of the connectors protect them from test pressure and will be removed later on. --Photo by Geoff Cram
