Variable Band-Pass Wave Recorder and its Use at USNEL Oceanographic Tower.

Abstract

A pneumatically filtered wave recorder was built, using a differential pressure transducer as the sensing device. The pneumatic filters are analogous to electrical RC-circuits, passing waves only in a desired pass band. With the proper choice of filters, the tide or swell or both can be attenuated to a great extent. Hence the record obtained is free from swell noise so that longer period waves can be seen.
