The Rappahannock Shoal and spoil disposal area investigated encompasses an area of approximately 180 square miles. The initial sampling program (1961) consisted of the establishment of a series of transects across the survey area. One hundred sampling stations were located along the established transects.

Inasmuch as the texture of the bottom sediments varied distinctly from place to place within the mid-bay region, the initial objective was to delineate the sediment distribution. Ninety-eight core samples were taken from the area with a modified Phleger coring device and analyzed in detail for textural characteristics. Representative stations were chosen and core samples were taken from these for complete chemical analyses.

The benthic fauna population is dependent upon many environmental factors. Grab samples were taken at each station with a standard Petersen dredge in order to evaluate the benthic population over the entire area.

Sampling programs were modified during 1962, 1963, and 1964 to gather more information on the specific areas of interest, namely the Rappahannock Shoal Channel area and the spoil disposal area. A more detailed description of the techniques employed is included in each section.
