Burreson INTRUDUCt T O N Purpose and Scope ot th e St, lncreasing demand for petroleum and natural gas In the United States has led to a need for development of reliable new domestic ;,ources . The Outer Continental Shelf of the United States holds great interest among the oil companies for possible exploration and development of oil and gas resources to meet tnis need . This Interest was demonstrated for the Middle Atlantic Outer Continental Shelf in the oil companies' response to the lease sale conducted in August 1976 . Of the 134 tracts comprising 876,750 acres offered for lease in August 1975 for exploratory drilling in the Baitimore Canyon Trough (Figure 1), oil companies purchased drilling rights to 101 tricts comprising 575,011 acres . The Bureau of Land Management Environmental Studies Program was established to provide information needed for prediction, assessment, ar.d management of impacts on the human marine and coastal environn:ents of the Outer Continental Shelf and the nearshore area which may be affected by these drilling activities . The studies are designed to : 1 . "Provide informat`.on on the status of the environment upon which the prediction of the impacts of Outer Continental Shelf oil and gas development for leasing decisionmaking may be based, 2 . provide information on the ways and extent that Outer Continental Shelf development c .:n ~otentially impact the human, marine, biological, and c ;,aatal areas, 3 . ensure that information alrea .iy available or being collected under the program is in a form that can be used in the decisionmaking process associated with a specific leasing action or with the longer term Outer Continental Shelf minerals management responsibilities, and 4, provide a basis for future monitoring of Outer Continental Shelf operations ." The Virginia lustitute of Marine Science began Bureau of Land Management support_ .- research or. the Middle Atlantic Outer Continental Shelf in October 19 7 : . The principal objectives of the first year studies were to provide chemical and biological data on conditions existing prior to oil and gas development, and on processes -egulating biological community structure or levels of chemical constit6ents in I
