Freely Drifting Swallow Float Array: May 1987 Trip Report
Abstract
Representative data collected by the MPL's Swallow floats during the 5-6 May, 1987 deployment near 32.5 deg N, 120.5 deg W are presented. The results include the 8 kHz acoustic localization ping arrival data, the battery voltage, compass heading, and AGC level measurements, and the three-component, VLF particle velocity data. The data set is of extremely high quality and it appears to provide a rich source of information on ambient ocean noise in the 1-20 Hz band. Data from the concurrent deployment of 13 ocean bottom seismometers are also presented. These data include the three-component geophone data from the nine properly functioning instruments (instruments 1, 2, 4, 5, 6, 8, 12, 13, and 14), regular OBS hydrophone (OAS model E-2PD) data from instruments 2, 4, 8, 12, 13, and 14, and data from ultra-low frequency hydrophones of the Cox-type design on instruments 1, 5, and 6. A preliminary comparison between the OBS data and the Swallow float geophone data show some common spectral peaks and that calibrated spectral levels are comparable. To help interpret the acoustic/ seismic data collected by the instruments, plots of the position of the R.V. Scorpius are given.
