The frequency of multibeam bathymetry is measured in kilohertz (kHz), one thousand periods per second.
Horizontal coordinate information projected in Universal Transverse Mercator (UTM) Zone 19 is referenced to the North American Datum of 1983 (NAD 83); horizontal information in geographic coordinates is referenced to the World Geodetic System 1984 (WGS 84). The vertical datum for tidal-zone measurements is mean lower low water (MLLW).
