This data set represents the boundaries of federal lands adjacent to the Barrow Environmental Observatory (BEO). These areas are owned by the National Oceanic Atmospheric Administration's Climate Monitoring and Diagnostics Laboratory (NOAA CMDL), the United States Geologic Survey and United States Navy.
This data set was compiled for the Barrow Arctic Science Consortium (BASC) which is responsible for managing the Barrow Environmental Observatory (BEO) which is adjacent to these federal lands.
These lands were withdrawn from the Naval Arctic Research Lab.

This data set is being archived as part of the Barrow Area Spatial Data Infrastructure effort. This project is made possible with funding from the National Science Foundation (NSF Award OPP-0004401) and the US Geological Survey (USGS Award Number: 03HQAG0177) to the Barrow Arctic Science Consortium (BASC).
This data set is topologically correct.
Data set is considered complete.
Differential GPS data was collected. The data was processed using Trimble Geomatics Office (TGO) version 1.5 and the precision of the survey points were obtained from the adjustment report created by the software. The worst horizontal positional accuracy was .5 cm for the corner points which were obtained via a static DPGS survey.
Based on error calculations in Trimble Geomatics Office

The effort to document and archive Barrow Area data has been led by BASC through contracts with MSU and Nuna Technologies.
DGPS points were surveyed by MSU staff (Craig Tweedie, Shawn P Serbin, David Zaks) in 2003. The boundaries of the federal lands were then generated in ArcGIS by incorporating DPGS corner points for the southern boundary and infromation from the federal registry. Final processing and quality control check was performed by Allison Graves, Nuna Technologies. Following is a summary of the DGPS surveys: The first 8 corner points of the BEO were surveyed on June 23, of 2002. For each corner point, a standard static survey configuration was used, consisting of the BiPod, Rover Receiver, as well as the Zephyr antenna. The base of the BiPod positioned in the center of each survey cap, previously placed to mark the location. In the center of the survey caps there is a small indentation which was used to orient the base of the BiPod for the survey. The height of the antenna was obtained by first measuring the height of the survey cap above the ground, then measuring to the bottom of the antenna mount on the BiPod. To clarify, the height above the cap was found by measuring from the top of the cap to where the base of the antenna and the top of the pole meet. The positions were logged for at least 20 minutes, in order to allow enough time to obtain accurate coordinate information for the points. Corner points 9 and 10 were surveyed on July 8, 2002 in the same fashion as those above. Corner point location 11 was surveyed on August 15, 2002 while in route to another survey. The method used was exactly the same as the other corner points. Corners 13 and 14 were surveyed on August 16, 2002 also in the same manner as the other points. The shoreline boundary along Elson Lagoon was surveyed as a line by walking along the tundra edge.

This data set includes the boundaries for federal lands adjacent to the BEO Science Research District. In addition to the standard default ESRI attributes a field called "Name" was added for labeling purposes.
This data set contains 3 polygons representing federal lands along with their respective names. For additional information about the default attributes that are generated for ESRI shape files see the documentation associated with ArcGIS software or visit the ESRI web site at www.esri.com
