Sea surface height anomaly determined from an array of Pressure-recording Inverted Echo Sounders (PIES) in the Gulf of Mexico, 2019-06-14 to 2021-05-19

This dataset contains sea surface height anomaly (SSHA) determined from 72-hour low-pass filtered, 12-hour subsampled in situ data from an array of Pressure-recording Inverted Echo Sounders in the Gulf of Mexico from 2019-06-16 to 2021-05-19. Total SSHA as well as its two constituents, SSHA_ref determined from bottom pressure and SSHA_bcb calculated from geopotential height integrated to a common deep level for all sites, are provided at 12-hour intervals. Geopotential anomaly is calculated from 72-hour low-pass filtered travel time data and GEM lookup. SSHA_ref represents the contribution of mass loading. SSH_bcb results from density variability in the water column where bcb is shorthand for baroclinic referenced to the bottom. Diurnal, semidiurnal, lunar monthly and fortnightly tides were removed from the bottom pressure before calculating SSHA. The data are in NetCDF format. Associated data are available in datasets U1.x852.000:0003 (DOI: 10.7266/K4ZF1T9Z; currents), U1.x852.000:0004 (DOI: 10.7266/BZ9B3C54; pressure and temperature), U1.x852.000:0005 (DOI: 10.7266/4B13NKBA; vertical acoustic travel time), and U1.x852.000:0007 (DOI: 10.7266/GE30701Z; estimates of vertical profiles of temperature, salinity, and geopotential anomaly).
