MEASUREMENT OF THE STATISTICAL PROPERTIES OF THE OCEAN SURFACE WITH INSTRUMENTED SURFACE FLOATS. PART II: ENGINEERING AND DATA PROCESSING.

Abstract

Gyro-stabilized vertical accelerometer-roll-pitch-heading floats, special analog processing equipment, a digital recording system, and a group of interconnecting computer processing routines incorporating the fast Fourier transform have been created to measure roughness properties of the ocean surface caused by gravity wave components with frequencies extending up to 1 Hz. The first portion of the report is a summary of the engineering and data processing effort. This is followed by processed surface wave data recorded under nearly stationary statistical conditions during a combined acoustic-oceanographic experiment. A smoothed directional spectrum, probability distributions for surface particle motion in three dimensions, power spectra of wave height and slope, energy flux, and many other examples, are presented.
