FIELD: oceanography; remote control of sea swell.
SUBSTANCE: secured on positive buoyancy buoy are two spherical negative buoyancy backings. First backing is hollow and elastic and is used for securing measuring fiber coil of interferometer and other coil of interferometer is wound on second spherical backing. Inertial mass in form of metal ball for example is placed inside hollow backing. Both backings placed on sea surface and are subjected to action of sea waves. Signal at interferometer output is proportional to intensity of sea swell.
EFFECT: enhanced efficiency of obtaining information on sea swell.
