Eustatic sea level fluctuations control all important processes
which shape coastal areas, not only in the aspect of the environment
and ocean dynamics, but also geochemically. During the past
500,000 years of the Quaternary, the sea has oscillated in a manner
as rapidly as ever observed, and it is projected that the rise in sea
level will accelerate in this century due to climate change. It is
pertinent that the sea level rise and its transgressive effect is systematically
studied, most especially in low lying coastal areas in
proximity to the Atlantic.
