Outer Continental Shelf oil and gas activities in the mid-Atlantic and their onshore impacts: A summary report, November 1979: Update 1, June 30, 1980

The Master Water Data Index (MWDI) of the U.S. Geological Survey's National Water Data Exchange (NAWDEX) is a computerized data base which contains information about water data collected at specific sites. The data base identifies the organization collecting the data, the site location, the major types of data collected, the period of collection, and the frequency of measurement of major parameters for each type of data. This manual contains instructions for the encoding and keypunching of information for entry into the MWDI.

Updates are published approximately every 6 months to provide new and revised information. A new Summary Report will be published only if a significant event occurs in the Region. This update covers new drilling operations in the Lease Sale 40 and 49 areas, information on the status of the upcoming Lease Sale 59, and an update on studies relevant to OCS-related planning activities.

The organization of the update parallels that of the first Mid-Atlantic Summary Report. A copy of the Summary Report (USGS Open-File Report 80-17) can be obtained from the OCSIP. The address is listed on the reverse side of the title page.
