buoys are deployed throughout the world, mainly near
coastlines, but also in the deep ocean, to measure winds and
temperatures as well as wave heights and direction. Waves
are measured using an accelerometer, an instrument that measures
the vertical acceleration of the buoy as the wave passes.
Inside the buoy are very large marine batteries that are recharged
by solar panels on the buoy. This provides the necessary power
for the buoy to operate and to send its data to either geostationary
or passing polar orbiting satellites.
This information is used by government agencies like the National
Weather Service for producing marine forecasts as well as
by commercial, and public fishing and boating interests for
planning voyages. |
