Abstract:
An important driver of regional sea-level change is ocean dynamics. which induces changes related to ocean density and circulation. The role of ocean dynamics in connecting the open ocean to sea level at the coast currently represents a key knowledge gap in climate science. In this seminar, I'll talk about how a local current, the Shelf break jet (SBJ), is related to sea level along the U.S. East Coast. I'll present 7 years of velocity data of the SBJ from the Ocean Observatory Initiative (OOI) Coastal Pioneer Array. Located at the New England shelf break, about 75 nautical miles south of Martha's Vineyard, the Array has seven site moorings, spread from the shelf to offshore of the shelf break. Each mooring contains, among other instruments, an upward-looking ADCP, which measures three-dimensional velocities throughout the water column. Using spectral analysis, I'll then show how the SBJ and coastal sea level, based on tide gauge data, are related. Our results show a high correlation on the 1-15 days frequency band, from the South of New England to as far south as the Delaware coast, depending on frequency. Since the 1-15 days frequency band coincides with the frequency variability of storm surges, I'll finish the talk with some implications for coastal flooding.
