Position fixing and satellite imagery have developed to a point at which they can be used to position a ship within 10m, to detect objects less than a metre in size, and to plot coastal fronts and o

Heretical

The Intertidal Zone,On most coasts the tide’s amplitude is large enough to expose and cover a strip of land, the intertidal zone, twice each day. The cause and variability of tides have already been discussed (Chapter 2). Here we shall consider the intertidal environment and the animals and plants living in it.

Assuming no atmosphere, sea and land surfaces exposed perpendicularly to the sun’s energy would receive about 1.36 k W m . (this figure is called the solar constant). They receive much less because scattering, absorption, and reflection takes place in th

The atmospheric pressure at sea level is called . and is caused by the weight of air above. This weight is on average 1.033 kg cm . or 14. 7lb in ., and is equivalent to the weight of
