Geological cross-section showing locations of GPS receivers, and tide gauges from College Station to Galveston Pier 21, TX to Eugene Island and Grand Isle, LA to Cedar Key, Cross City and Daytona Beach, FL (A-A′ in Fig. 1). GPS receivers SG32 and XCTY measure LSBR19; tide gauges Galveston Pier 21, Eugene Island, Grand Isle, Cedar Key and Daytona Beach measure RSLR. The dashed lines are based on previous studies32,33,34. Land-surface elevation is from Google Earth Pro. RSLR values are from NOAA4. GPS LS values are from GLOSS12 and JPL11. Upward pointing red arrows indicate RSLR at tide gauge stations and purple downward pointing arrows indicate LS at GPS stations. See Table 1 for geological layer symbols and Supplementary Fig. S2 for aquifer systems in the Houston–Galveston region.
