A Brief Introduction to Sea & Space Sea & Space International Steering Committee |
Satellite images of coastal regions can accurately map phenomena such
as temperature, roughness, and marine life concentration. Around an estuary,
sediment from a river can be charted far out to sea. Tidal areas can be
mapped. Pollution incidents can be clearly visible. Around bays and headlands,
strong local variations often perilous to mariners can be identified.
In modern times, a range of high-tech electronic systems have been developed, starting with radar - Britain's "secret weapon" in world war II - and sonar for underwater work. Early electronic systems such as DECCA/LORAN for highly accurate coastal navigation were developed for harbour navigation and offshore industries.
Most recently, the high-tech star charts - the American GPS and Russian GLONASS systems use highly complex but synchronised satellite constellations. Like the old star charts, they work by triangulation. The major advantage - they don't stop working in bad weather!
The water cycle on Earth is fundamental to life, and its study hydrology is a science in itself. Applications of satellite data are endless, from meteorology - the familiar weather pictures - to local detection of surface water; from the global ocean currents of the Gulf Stream and El Niño to the local currents that make a safe harbour or deadly rocks; from ship and pollution to marine life and plankton.
Did you know that global warming may mean a local ice age for much of Europe? Our climate is kept warm by the Gulf Stream, but just a little melting of the Greenland ice cap could leave us - from northern France, through the British Isles and the low countries to Norway - more like Alaska?
Selected works will be featured on the Sea and Space server.
We are looking for contents - studies that use the satellite data to show
something interesting or useful. But we are also interested in
how
you reached your results. You are encouraged to explore new ways of using
the Internet in your work.
