Ocean mass, sterodynamic effects, and vertical land motion largely explain US coast relative sea level rise

T. C. Harvey, B. D. Hamlington, et al.

This research, conducted by a team of experts including T. C. Harvey and B. D. Hamlington, unveils the intricate interplay of ocean mass changes and land motion contributing to sea-level rise in the contiguous U.S. They meticulously analyze tide gauge data from 1993 to 2018, shedding light on the relative trends at 47 locations, while raising questions about unexplained anomalies.

Abstract
Regional sea-level changes are caused by several physical processes that vary both in space and time. This study quantifies the influence of contemporary ocean mass change, sterodynamic effects, and vertical land motion on sea-level rise observed at tide-gauge locations around the contiguous U.S. from 1993 to 2018. The authors explain tide gauge-observed relative sea-level trends at 47 of 55 sampled locations. Locations where trends cannot be explained are potentially indicative of shortcomings in the observational network or uncertainty estimates.
