Freely Drifting Swallow Float Array: July 1989 Trip Report

Abstract

Representative data collected by the Marine Physical Laboratory's (MPL) Swallow floats during the 8-9 July, 1989 deployment are presented herein. As part of the Downslope Conversion experiment, the Swallow float deployment was conducted near 34 50' N, 122 20' W, about 150 km west, northwest of Pt. Arguello, California. This report presents the Swallow float deployment locations, the positions and characteristics of know signal sources, expendable bathythermograph (XBT) and anemometer data, and representative Swallow float data from the experiment. The Swallow float data include battery voltage, compass heading, and automatic gain control (AGC) measurements, the 8 kHz acoustic localization ping arrivals, and the VLF pressure and particle velocity data. All 12 Swallow floats operated nearly flawlessly, resulting in a 95% full data set. The data set is of extremely high quality and it appears to provide a rich source of information on signal propagation in the 1 to 20 Hz (VLF) band. Graphs.
