tec...Sea level variations prior to the launch of satellite altimeters are estimated by analysing historic
tide gauge records. Recently, a number of groups have reconstructed sea level by applying EOF
techniques to gappy data. We complement this study with alternative methods. In a first step gaps
in 178 records of sea level change are filled using the pattern recognition capabilities of artificial
neural networks. Afterwards satellite altimetry is used to extrapolate local sea level change to
global fields. Patterns of sea level change are compared to prior studies. Global mean sea level
change since 1900 is found to be on average 1.65 mm per year.Read More
