Abstract
A small meteorological buoy suitable for mesoscale research was developed at NOAA's Pacific Marine Environmental Laboratory. The GEM (Goes Environmental Monitor) buoy transmits data via the GOES satellite, which eliminates the need for internal tape recording. Vector averaged winds, scaler winds, air temperature, water temperature, and maximum gusts are measured. A sketch of the buoy moored in 100 m of water is presented. The hull is a 1-m-diameter, foam-filled aluminum sphere with a .38-m-diameter cylinder extending through the center. When ballasted to the equater of the sphere, the buoy displaces 260 kg. The natural frequency in pitch and roll is approximately 1.8 seconds, but the suspension of a 120 kg weight 10 m below the buoy provides a double pendulum which effectively damps high frequency wave excitation.
