These control points were selected randomly from the water density data points, using Hawth's Create Random Selection Tool. Twenty-five percent of each seasonal bin (for each year and at each depth) were randomly selected and set aside for validation. For example, if there were 1,000 water density data points for the fall (September, October, November) 2003 at 0 meters, then 250 of those points were randomly selected, removed and set aside to assess the accuracy of interpolated surface. The naming convention of the validation point feature class includes the year (or years), the season, and the depth (in meters) it was selected from. So for example, the name: ValidationPoints_1997_2004_Fall_0m would indicate that this point feature class was randomly selected from water density points that were at 0 meters in the fall between 1997-2004. The seasons were defined using the same months as the remote sensing data--namely, Fall = September, October, November; Winter = December, January, February; Spring = March, April, May; and Summer = June, July, August. This data was created in order to support a biogeographic assessment of the Stellwagen Bank National Marine Sanctuary.

Conceptual Consistency The accuracy of these interpolated water density rasters were validated. In order to do so, 25% of the water density measurements were set aside before the interpolation. After the interpolation, the corresponding validation points were intersected with the interpolated rasters to calculate a simple difference between the observed (validation points) and the predicted (interpolated surface) measurement. These validation points and values are located in the Water_Stratification_Points geodatabase, Validation_Points feature data set. Water density rasters were interpolated for each season (winter, spring, summer fall) from water density (sigma t) point data using a Radial Basis Function (spline with tension) at 0 and 50 meters. The 0m water density raster for each season was then subtracted (using the raster calculator in ESRI's Spatial Analyst Extension) from the 50m water density raster for the same season. 2005-12-01T00:00:00
