Eastern Mineral and Environmental Resources Science Center
The spatial and temporal density of samples collected during an environmental investigation affect the outcome of the study by limiting or enhancing our ability to see the effects of various natural process and to resolve the effects of individual point sources or regional sources of contaminants. This subtask will use a variety of regional and local (spatially concentrated) data sets to evaluate the spatial and temporal density of sampling that is needed in an environmental assessment.
One of the main objectives of this project is to combine a regional environmental assessment with a quantitative mineral resource assessment of the same area. A Challenge that exists in this approach is the mismatch of spatial scales and spatial density of the data used in the inputs for the two types of assessments. The objectives of this subtask were to determine what level of interpretations of a dataset are possible for a given density of sample collection, and to use that information to determine the spatial density of data required to reduce the uncertainty in a mineral-environmental assessment for a large area.
