"Long term maintenance and costs involved in the operation of a shallow water habitat"

The shallow water research habitat, LoraI, has been in operation for three years and is capable of supporting a variety of underwater activities, using three types of diving routines. Since the completion of major repairs, expenditures required for physical maintenance of the facility have averaged at $4,700.00 per year. This does not include salaries and expenditures for new hardware. The most expensive aspects of the maintenance have been directly associ- ated with requirements for operation in the cold water environment.
