evidence: Although the shorter records have proved to be useful, there naturally continues to be most interest in the longer ones. Fig. 5(a) presents a scatter plot between the tide gauge trends for the 20th century for the five long record stations alone (from Table 1) and their corresponding geological values. One obtains similar conclusions as from Fig. 4. The offset is 1.37 ± 0.24 mm yr−1, similar to that based on all stations. The most outlying of the five appears to be Newlyn, either because its tide gauge MSL trend is too low or its geological rate suggests too much submergence. This anomaly in the Shennan & Horton (2002) data set has been remarked upon by Gehrels (2006). Fig. 5(b) includes the same MSL data but this time compared to rates of vertical land movement based on an updated combination of continuous GPS (CGPS) and AG data using the methods of Teferle et al. (2006, 2008) and Bingley et al. (2007). In this case, the offset is 1.06 ± 0.16 mm yr−1 (standard error again based on tide gauge errors. This can be increased by 30 per cent if the large CGPS/AG errors are also considered.).
