5.3.4 Sea Surface Level and Heat Content of the Ocean
Upper Layer
Sea surface level is usually presented as mean sea level, that is the average height of
the sea
s surface. Detection of long-time variations of mean sea level can provide
information on climate change. During the 20th century, the World Ocean surface
level rose by 0.1
'
0.2 m. Apparently, this was caused by the thermal expansion of
sea water and ice melting on land due to the global warming. The rate of the World
Ocean level rise in the 20th century apparently exceeded that observed during the
last 3,000 years by a factor of ten. Beginning from the end of the 1950s (when SST
changes became large-scale), the heat content of the ocean upper layer has also been
