Understanding sea-level rise - improving predictions through studying the shape of the seabed
In many places around the world, data clearly shows the level of the sea is rising. In low lying coastal areas, even small increases when coupled with high tides and storm surges have had devastating consequences, such as altering coastlines, impacting offshore energy infrastructure and displacing populations. A better understanding of factors influencing sea level is vital in order to prepare for and mitigate its impacts.
