Arguments

depthDatumName	The identification given to surface of reference from which depths are measured. See `depthDatumName()`
depthResolution	The minimum distance possible between two adjacent depth values, expressed in Depth Distance Units of measure. See `depthResolution()`
depthDistanceUnits	The units in which depths are recorded. See `depthDistanceUnits()`
depthEncodingMethod	The means used to encode depths. See `depthEncodingMethod()`
