WAVEMETER: A LAND-BASED SYSTEM FOR MEASURING NEARSHORE OCEAN WAVES

Abstract

This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data from the stations are relayed via teletype to the National Weather Service for use in making and verifying wave forecasts.
