at tide gauge stations that are not monitored by collocated GPS stations.
The idea is that surges in sea level recorded
at tide gauge stations can tell us about strong hurricane events.
But a new paper by Grinsted et al. has found evidence of past cyclone occurrence in the western Atlantic which impacted the U.S. east coast, evidence which is homogenous over a period of nearly a century, by studying not storm records, but surges in sea level recorded
at tide gauge stations.
