NGS GRAV-D Airborne Survey Concludes in Alaska

National Geodetic Survey's Gravity for the Redefinition of the American Vertical Datum (GRAV-D) airborne survey has wrapped up operations out of Fairbanks, Alaska. The survey was conducted aboard a NOAA WP-3 Hurricane Hunter. More than 150 hours were flown, allowing for new data collection over the Arctic Ocean and the northern Alaska coast. The GRAV-D Project has now completed 13.45 percent of the total GRAV-D Project area for the United States, bringing the project ahead of its 13 percent goal for this fiscal year. More flights are planned for this summer on another aircraft, to bring the project closer to its 15 percent "stretch goal" for fiscal year 2011. For more information, contact Vicki Childers.
