Phi-notation (Krumbein, 1934) as used in this report is defined as: Φ = -log 2 (d), where d is the grain diameter in millimeters. Phi-class intervals in millimeters are given in the data dictionary of the Sediments section of this report.

The frequencies of multibeam bathymetry are 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 (NAD83); horizontal information in geographic coordinates is referenced to the World Geodetic System 1984 (WGS84). The vertical datum for tidal-zone measurements is mean lower low water (MLLW).
