Is there a hot spot of sea-level rise acceleration along the mid-Atlantic United States? A Gaussian process decomposition of tide gauge records

To test a hypothesized faster-than-global sea-level acceleration along the mid-Atlantic United States, I construct a Gaussian process model that decomposes tide gauge data into short-term variability and longer-term trends, and into globally-coherent, regionally-coherent and local components. While...
