BOEMRE has developed offshore administrative lines from each
adjoining coastal state as described below. The BOEMRE undertook this task
in light of the increasing number and type of both traditional and
non-traditional energy, alternative energy-related, and other activities
on the OCS. We have used, to the extent practicable, the updated National
Baseline (or Supreme Court fixed baselines where they exist) to derive
offshore administrative boundaries in compliance with accepted cartographic
practice. For this task, BOEMRE has used the computational software known
as CARIS LOTS "Limits and Boundaries". This software was specifically designed
to meet international standards for calculating marine boundaries, including
United Nations Convention on the Law of the Sea (UNCLOS) requirements.
For additional details please see the
January 3, 2006 Federal Register Notice.
Below are maps, GIS shape files, and ascii text files for the coordinates
of these Administrative Boundaries. These coordinates are preliminary,
pending final review. As any changes or updates are made, they will
be posted here.

In the Atlantic Region, all Administrative Boundaries have been computed
using the National Baseline and are pending final review.
