<< 10/12 < > For the last century, the global level of the sea appears to have risen at an average rate of nearly two mm/yr. However, in any given region, the apparent rate of rise can vary considerably from the long term global value. Geographical and temporal variations from the long-term mean value occur from a variety of causes such as interdecadal fluctuations of ocean density and circulation, continuing isostatic adjustment of the land level from the last deglaciation, subsidence due to the extraction of underground fluids, and others. The middle Atlantic region of the U.S. east coast gives a good illustration of this phenomenon.
