Publication - Sea surface height variability in the North East Atlantic from satellite altimetry
This paper examines the spatial variation of sea surface height trends in the North Sea
Basin as seen by satellite altimetry and assesses its underlying causes. Changes in the
potential temperature and salinity of the North Sea are transposed into corresponding
changes in sea surface height and regional anomalies of linear sea level trend calculated.
The same is carried out for the meteorological processes which act on the sea surface.
The steric and meteorological regional sea level rise anomalies are summed with those
from contributions from land ice and compared against the values seen by satellite altime-
try over the period 1993 - 2014. Results show that there is good agreement between the
observations and the reconstruction. The local meteorological contribution appears to be
most important in describing regional variation in linear sea level rise and is reinforced
with a local halosteric contribution which shows a similar spatial pattern.
