Nonlinear absolute sea-level patterns in the long-term-trend tide gauges of the East Coast of North America

The paper provides an estimate of the latest relative and absolute rates of rise and accelerations of the sea levels for the East Coast of North America. The computation is based on the long-term trend (LTT) tide gauge records of the relative sea levels and the Global Navigation Satellite System (GN...
