Sea-Water Environment for the Mel Ocean Pressure Laboratory, Phase II. Sea-Water Acquisition, Processing, and Control of Parameters

摘要

Investigation of the different factors concerning the sea-water environment for the MEL ocean pressure facility determined that the water should be gathered by barge from Raleigh and Onslow Bay, North Carolina, or near the 100-fathom curve off the mouth of Chesapeake Bay: upon arrival at the Laboratory, the water should be filtered to remove biological life and brought to the proper salinity by addition of freshwater or concentrated natural seawater; further control of properties such as O2, CO2 can be accomplished by purging with compressed air; the environment should be monitored frequently during introduction of new seawater into the facility and during experiments to ensure uniform conditions; and the water should be renewed after each experiment or at least once a day. Finally, a proposed processing system was illustrated showing how the different equipment and procedures discussed would work in an actual system. (Author)
