These oceans, of course, are connected to each other, and can be looked upon as one super-ocean with many branches (Figure 1.1). The Pacific is the largest, a

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 ocean surface would then be 2.64- 2.44 = 0.2 km (200 m) above present sea level. The earth’s surface is not at minimum potential energy however; it is concentrated at two levels. The continents and continental she

,Der betriebswirtschaftliche Umsatzproze?,(Figure 9.1). Sea food is perhaps the only world food whose yield is increasing more quickly than human population growth. The world’s fisheries are based on only a few of the 20 000 species of marine fish, and three major groupings of developed countries dominate the world market. The western Europ
