(a) The CMSL, created by averaging the 10 tide gauge records; (b) the CMSL after adjusting for reservoir impoundment using estimates from Chao et al.42; (c) the GMSL; and (d) the GMSL after adjusting for reservoir impoundment, again using the estimate from Chao et al.42 Hatched area identifies plot regions where accelerations are significantly different from zero (95% confidence interval).
