The authors compare their 2 sites on the NE Atlantic to 2 others in the NW Atlantic: New Jersey & North Carolina, which show relative sea level rise due to subsidence.
The paper demonstrates that relative sea level rise is predominantly a regional phenomenon due to land subsidence or uplift. Relative sea levels in areas little-affected by land height changes are changing very slowly over time - only about 3 to 4 inches per century - which is the only true sea level contribution from warming.
