Depth to 50 percent probability of oxic conditions, Chesapeake Bay Watershed
Description
This dataset is a 900 meter resolution raster representing the depth in meters at which the probability of oxic groundwater occurring is at least 50%, for the Chesapeake Bay watershed. Oxic groundwater was defined as containing O2 values >= 2 mg/L. The values range from 0-100 meters, with 100 representing all depths greater than 100. It was created in support of models which define the oxic/suboxic interface, which is important for determining pathways for nitrate transport in groundwater and in streams. The dataset was derived from a logistic regression of variables representing surficial geology, position in the flow system, and soil drainage.
