Approved for public release; distribution is unlimited / Capacitance and conductance measurements using two and
four wire techniques were developed and statically and
dynamically calibrated in this thesis. The voltage
sensitivities range from 7.3 to 8.1 ± 0.1 mV/cm for the two
wire capacitance system static calibrations. This is ± 5.2%
of the limiting theoretical value. The voltage sensitivities
range from 0.3 to 0.4 ± 0.1 V/cm for the four wire
conductance system static calibrations. Dynamic calibrations
were only completed for the conductance system. The dynamic
calibration results were weakly frequency dependent with a
qj-0.15 decay in a limited, 2-4 Hz range. Wind power spectrum measurements were taken in the
existing Upper Ocean Simulations Facility at the Naval
Postgraduate School. There was excellent agreement in the
spectra with both techniques.
Driven gravity wave frequency downshifting and wind
energy dumping was observed in the combined gravity wave and
wind-wave measurements. The power spectra peaked near two
Hertz and decayed at 50 to 70 dB per decade, or as CO
-5 to
G)" 7 for both systems. Gravity wave phase speed and wavelength measurements
were performed with the capacitance system. The results were
approximately 40% higher than theory. / http://archive.org/details/developmentcalib00yarb
