Bathythermographic Surveys Near Naval Facilities at Point Mugu, California, and Pearl Harbor, Hawaii.
Abstract
The use of naturally cold sea or lake water in place of mechanically chilled water in air conditioning systems was found to be a feasible and energy saving concept for Naval Facilities like those at Point Mugu, CA, and Pearl Harbor, HI. The economic feasibility of this type of air conditioning at these sites depend on the distance and the water depth of the cold water source at the sites. In order to determine these distances and these depths, surveys were conducted which involved (1) assembly of existing data on seawater temperatures and (2) measurement of these temperatures with expendable bathythermographs (XBT). A summary of this existing data and the results of these measurements are given in this report. On the basis of this data and these measurements, estimates were made of the profiles of maximum annual seawater temperature which are also given. It was found that the maximum annual bottom water temperature at the Point Mugu site can be expected in November; it is 10 C (50 F) at a depth of 190 M (620 ft) 1.4 NM offshore. This temperature at the Pearl Harbor site can be above 10 C at a depth of 420 M (1,380 ft) 4.0 NM offshore. (Author)
