Modern Information On World Ocean Current Eustasy

Abstract

The eustasy, sea level climatic fluctuation, is a constant phenomena, which according the warm and cold climate cycles and fluctuations can be positive or negative. Nowadays, World ocean current eustasy is positive, which collaterally and together with climate worming causes its level elevation. In the beginning (1985-2010-th) of climate current 90 y. fluctuation, the eustasy is accelerated: at high latitude ice sheet acting zone at rate of 30-35% and 10-20% - at lower ones respectively. Mentioned phenomena significantly increased the inundation probability and disaster risk of population (~1, 5 billion), living on coastal lowlands and river mouths areas. The mitigation or reduction of probable disasters is possible by the way of early warning systems and appropriate hydro technical constructions application. For effective implementation and exploitation of the latter it is necessary to know the eustasy’ local and regional parameters. The sea level statistical series is the best source of such parameters calculation, regressive analysis of which is one of the most operative and reliable way to receive their accurate values.
