Description:
Abstract:
ADCIRC Coastal Circulation and Storm Surge Model is a system of computer programs for solving time dependent, free surface circulation and transport problems in two and three dimensions. The model was used by Applied Science Associates to provide an estimate of the maximum tidal currents experienced in the Massachusetts ocean management planning area during a tidal cycle. These GIS data are rough polygonal approximations of areas where tidal currents are thought to exceed 2.75 knots based on results from the ADCIRC tidal circulation model: <http://adcirc.org/>.
Purpose:
These data were used in the development of a comprehensive ocean management plan to protect critical marine resources and foster sustainable uses in Massachusetts state waters as mandated in the Oceans Act of 2008.

Title: velmax_50m
Geospatial_Data_Presentation_Form: raster digital data
Other_Citation_Details:
This geobase raster data set contains the maximum (spring tide) current speed in the Massachusetts ocean management planning area (and extended rectangular region ~ 6 nautical miles from the southern planning border) based on the sum of the M2 and S2 tidal components in the ADCIRC VDatum model. The tidal constituent model data is from the ADCIRC VDatum data described below. The data have been processed to estimate the maximum tidal current speed in a 50 x 50-meter grid. The processing was done using MATLAB with the tidal ellipse tool box written by Zhigang Xu (xuz@mar.dfo-mpo.gc.ca). The data from the ADCIRC tidal constituent model include the phase and amplitude of each tidal constituent at 161,131 points in the Gulf of Maine. These harmonic constituents for the eastward and northward velocity are converted to elliptical major and minor axis velocities using the ellipse toolbox. The maximum spring tide velocity is estimated from the M2 and the S2 tidal frequencies which are the two largest components of the tidal variability. The data product is therefore the estimated fortnightly (spring tide) maximum velocity. The ocean currents at any instant will never appear as they do in the figure. This is an estimate of the maximum that each location will experience over 14 days. The estimated maximum is exported from MATLAB and read into ArcGIS as a point file with location and speed data. The speed at each point in the 50 x 50-meter grid is taken from the nearest point in the triangular ADCIRC model grid nodes. This interpolation method proved to be the most efficient and reliable. Only tidal forcing mechanisms are considered in this model data. During storms the wind driven flow may far exceed the mean estimated here. About the VDatum Tidal constituent model, from VDatum and Strategies for National Coverage: "The first stage of each project is to develop the tide model used to compute the tidal datums. For this, high-resolution coastline data and NOAA bathymetry in the area are processed in a quality-controlled manner. This information is used to construct a high-resolution unstructured grid for use by the tide model. The standard tide model used in VDatum applications is ADCIRC, and modeled tidal datums are compared with datums computed from observations obtained by NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) for operating and historical tide stations. Model-data inconsistencies are adjusted using spatial interpolation techniques, and resultant tidal datums are provided to the VDatum software on a structured marine grid. NOAA's National Geodetic Survey (NGS) then uses these results to help compute the relationship between tidal datums and the North American Vertical Datum of 1988 (NAVD 88). NGS also provides the orthometric and ellipsoidal transformations used by the VDatum software."
