The National Research Council, in a series of evaluations of Minerals Management Service's (MMS) programs, has pointed out that while MMS is responsible for the activities on the federal offshore it does not have a standard statistical series that differentiates between activities on the onshore, the state offshore, and the federal offshore. While the Census on Minerals does collect data on the near and the deep offshore this is not published due to confidentiality problems, particularly in the deep water.
