SATELLITE OCEANOGRAPHY
Sensors mounted on satellites use various
wavelengths to monitor the Earth’s surface,
atmosphere, and oceans, as illustrated in
this computer-graphic montage of the Indian
Ocean. Visible light, infrared radiation,
and microwave data are all processed and
projected onto maps that chart the ocean’s
physical parameters. Satellites update the
maps on a weekly, daily, or hourly basis
to monitor ocean dynamics.
