Abstract

Sea level in the vicinity of Miami, Florida, is from three separate time series: Miami Beach (1932–1980), Haulover Pier (1982–1992), and Virginia Key (1994-present). In order to calculate the ensemble trend in Miami mean sea level (MSL), the three records must be merged with respect to the North American Vertical Datum of 1988. Because NAVD88 minus accepted MSL varies for the stations, the differences are treated as datum shifts, and are corrected accordingly. Thus adjusted, Merged Miami Sea Level (1932–2013) has a linear trend of 23.4 ± 1.3 cm/century, and along with logarithmic and polynomial least-squares fits, all three having a variance explained (r2 × 100) of 82.4%.
