This report describes the work carried out in the study and preliminary design of a Sea Water Simulator. The purpose of the device is to approximate for various locales and depths, the sea water chemistry represented by eight chemical parameters salinity, alkalinity, carbon dioxide, pH, oxygen, hydrogen sulfide, phosphate, and Eh. A literature search was conducted to elucidate this chemistry and to obtain data quantitatively interrelating these chemical systems and their physical states. A survey was made to compare the characteristics of commercially available control instrumentation and transducers. Based upon the information gathered, a system was then designed. The envisioned system incorporates computer control of both closed-loop and open-loop chemistries. Predicted accuracies for output composition control are reconciled with suggested USNCEL performance specifications.
