Summary
And Noah he often said to his wife when he sat down to dine,
‘I don’t care where the water goes if it doesn’t get into the wine.’
G. K. Chesterton, Wine and Water
Introduction
This chapter discusses a number of aspects of variability and long-term change in mean sea level (MSL). The changes take place on timescales of months through to centuries and can be studied with tide gauge, altimeter and some other data types, combined with different types of numerical modelling. The variations considered have amplitudes measured in centimetres or decimetres for most timescales and at most places. However, much larger variations do take place at some locations. For example, seasonal sea-level changes of around a metre are observed in certain parts of the Bay of Bengal in the Indian Ocean, and variations of several decimetres to a metre occur approximately every 3–7 years in the Pacific during El Niño events. A similarly large rise may occur throughout the world ocean during the next 100 years if some predictions of anthropogenic climate change prove correct.
