Abstract

The Ocean Ambient Sound Instrument System (OASIS) consists of a conventional RD Instruments ADCP modified to allow the recording of high quality, ambient sound from 1-75 kHz. In addition to the usual capabilities of an ADCP, this combination of acoustic instrumentation allows wind direction and speed to be inferred from a subsurface platform. The method of wind speed determination from ambient sound levels is explained identifying some of the limitations. The design of both the hardware and software required to make combined ADCP and ambient sound recordings is discussed, the methods used to preserve the large dynamic range characteristic of ambient sound. Observations made in the Norwegian Sea at OWS Mike are presented
