Decadal sea level trends in the Bay of Biscay from tide gauges, GPS and TOPEX
International audience Sea level time series derived from TOPEX altimeter and from tide gauge measurements in the Bay of Biscay (Eastern North Atlantic Ocean) are used to investigate the regional sea level rise. Altimetry sea level anomalies are computed from TOPEX measurements and resampled into fi...
