Phi-notation (Krumbein, 1934) as used in this report is defined as: Φ =
-log2
(d), where d is the grain diameter in millimeters. Phi-class intervals in millimeters are given in the data dictionary in the Sediment Distribution section of this report.
Current speeds are measured in knots (kt). 1 knot = 0.514 meter per second (m/s).
Horizontal coordinate information projected in Universal Transverse Mercator (UTM) is referenced to the North American Datum of 1983 (NAD 83); 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).
