MetadataShow full item record
Procedures for processing hourly observations of tidal elevation from NOAA/NOS tide gauges for the study of subtidal variability are outlined. Processing procedures include an adjustment for datum reference, low-pass filtering to remove the diurnal and semidiurnal tides, and a static correction for atmospheric pressure. These procedures are illustrated using a sequence of tidal elevation data from Santa Monica, California for the period 15 September to 15 December 1984.
