Where can I find data on long term sea level changes measured at UK sites?
Monthly and annual mean values of sea level measured at UK sites since the 19th century are contributed to the international Permanent Service for Mean Sea Level (PSMSL). Annual mean values of sea level from Aberdeen, North Shields, Sheerness, Newlyn and Liverpool, which are the five longest sea level records in the UK, are shown in the figure to the right. Time series from over 40 other UK locations can be obtained from the National Tidal & Sea Level Facility web pages. All NTSLF data are provided freely. 6. Are long term changes in sea level the same everywhere around the UK? No. Long term changes in sea level measured at the coast (e.g. by tide gauges) are a consequence of ‘real’ changes in the level of the ocean (e.g. due to climate change), to which must be added changes in the level of the land. Estimated rates (mm/yr) of crustal movement. Positive values indicate emergence (land rising relative to MSL). Most knowledge of the pattern of vertical land movements in the UK comes fro
