Datum String MHHW, MHW, MTL, MSL, MLW, MLLW, STND, IGLD, NAVD Offset (Not all services accept all these datums)
Unit String Meters (0) or Feet (1) The unit which the data is returned in. (Note that the reverse is true for "High Low Tide Prediction" service)
Time Zone int 0 (UTC) or 1 (LST) The time zone which the data is returned in. (Note that the reverse is true for "High Low Tide Prediction" service)
  
Water Level Data Output Parameters Please note that each dataset returns its own outputs as described in its corresponding WSDL file. Here is a summary of the output generated by the various datasets available as Web Services
Output Name Description
Time Stamp Date and time the data were collected by the DCP
WL Water level height
Sigma Standard deviation of 1 second samples used to compute the water level height
O Count of number of samples that fall outside a 3-sigma band about the mean
I A flag that indicates that the water level value has been inferred.
F A flag that when set to 1 indicates that the flat tolerance limit was exceeded
R A flag that when set to 1 indicates that the rate of change tolerance limit was exceeded
T A flag that when set to 1 indicates that the temperature difference tolerance limit was exceeded
L A flag that when set to 1 indicates that either the maximum or minimum expected water level height limit was exceeded

Water Velocity and Harmonic Constituents Please note that each dataset returns its own outputs as described in its corresponding WSDL file. Here is a summary of the output generated by the various datasets available as Web Services
Output Name Description
CS Current speed (knots)
CD Current direction (degrees true)
Time Stamp Date and time of the data
   
Constituent Number Order in which NOS lists the constituents
Name Common name used to refer to a particular constituent, subscript refers to the number of cycles per day. Please Click here for definitions.
Amplitude One-half the range of a tidal constituent
Phase The phase lag of the observed tidal constituent relative to the theoretical equilibrium tide
Speed The rate change in the phase of a constituent, expressed in degrees per hour. The speed is equal to 360 degrees divided by the constituent period expressed in hours
