Name: BOEM Block Aliquots

Display Field: BLOCK_NUMB

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Aliquots are generated from full Outer Continental Shelf (OCS) blocks by subdividing each block into 16ths and allow for more detailed boundary delineation in offshore energy leasing. The aliquots use a letter designation in addition to their parent protraction number and OCS block number (ie. NK-1802, 6822F). A full OCS block is 4800 x 4800 meters, while an aliquot measures 1200 x 1200 meters. Smaller, clipped aliquots are found along the Fed/State OCS boundary and along UTM zone borders. This dataset includes aliquots for 60 protractions out of the available 80 protractions in the Atlantic and 36 of 71 off the US West Coast . The remaining 56 protractions are located on the seaward edge of the OCS . Aliquots for these protractions will be produced at a later date as needed.
