- Title
Rates of sea-level rise from tide gauge measurements and satellite global positioning system along the Atlantic Coast of Africa.

- Abstract
This work aims to study the tide gauges of the west coast of Africa, from Gibraltar to the Cape of Good Hope. The relative rate of rise (RoR) of the sea levels is computed in every tide gauge satisfying minimum length and quality requirements. This information is supplemented by the satellite global positioning system (GPS) measurement of the subsidence of the land nearby the tide gauge to compute the subsidence rate. On average, the relative sea levels are rising along the west coast of Africa at a rate of less than +1 mm·year−1, with an overwhelming subsidence component, and negligible acceleration.
