A 6-point shallow buried ocean bottom seismometer and pressure gauge (SPOBS/P) array was deployed 2 km offshore of the Army Corps of Engineers’ Field Research Facility at Duck, North Carolina at 15-m water depth as part of the ONR sources of ambient microseismic ocean noise (SAMSON) experiments. An array element consists of three orthogonally mounted accelerometers and a pressure sensor and was buried approximately 1 m below the seafloor. The array aperture was about 1.2 km tuned for shallow-water microseism wavelengths. Although the array aperture is too large for gravity wave directional spectra measurements, the recently developed buried ocean directional spectrometer (BOWDS) method is used to measure the directional spectra of gravity waves simultaneously with the directional spectra of microseisms. The BOWDS method requires only the point measurement of pressure and the two orthogonal components of seabed motion [T. Nye etal., J. Atmos. Ocean Technol. 7, 781–791 (1990)]. Over 100-day continuous recording of real-time data was made starting 15 September 1990. The BOWDS results show good agreement with the linear 9-point array of pressure gauges. From this 100-day observation, a consistent pattern of microseism evolution was identified. Microseisms are suddenly activated right after the sudden shift of wind direction as multidirectional seas start to evolve. Fresh microseisms are generated at high frequency, say at 0.5 Hz at the beginning. As the seas get older, the microseisms at lower frequencies are generated. The evolution of microseisms follows the pattern of newly born seas. [Work supported by ONR.]
