Objectives of this project are to design, build, and test a                     very stable and sensitive deep sea pressure gauge.  Presently                   available pressure gauges drift over periods of time and                        under differing temperatures and their sensitivity is often                     inadequate for modern investigations.  Single crystal,                          semiconductor grade silicon has very few structural                             dislocations and foreign atoms.  This material has been                         proven to be inherently stable and suitable for use as a                        pressure transducer.  Methods will be developed for sealing a                   diaphragm to the silicon crystal in such a way that the                         transducer will be usable for periods of high pressure on the                   seafloor.  Various options for constructing electrodes and                      other electronic components will also be undertaken.  The                       system will then be tested at sea and calibrated.                                                                                                               Improved pressure sensors will have several applications in                     geophysical studies of the sea floor, in physical                               oceanography, and in industry.
