Our web site is moving!

We are in the middle of a transition from our old web site to our new server. Due to a lack of manpower, the web site is not very current. It will probably remain that way until January or so. For example, the web page access to data is not current, and only reflects data through August 22. The new server is http://fairweather.giseis.alaska.edu/akda/.

For access to all our online data, including all of the recent data, please use our anonymous ftp site ftp://fairweather.giseis.alaska.edu/pub/gpsdata/permanent/.

Also, because of the Denali earthquake Here are ITRF97 coordinates for CLGO for Oct 1, 2003. First in XYZ (in meters), then in lat-long-elevation.

What is the AKDA?

The Alaska Deformation Array (AKDA) is a GPS array consisting of sites established for a variety of research and practical purposes. Sites are operated by the Geophysical Institute to study crustal deformation in Alaska, by NASA for orbit tracking, by the U. S. Coast Guard for marine navigation, and by a private surveying company for general GPS base station use.

Data from all of these sites area analyzed routinely at the Geophysical Institute where they are used to study the deformation of Alaska.

Status Report

Updated: June 15, 1998

The purpose of this site is to make available GPS data and products from the University of Alaska Geophysical Institute's Alaska Deformation Array and other sites in Alaska operated by other groups. Data and site information can be accessed by clicking on the "Download Data" or "Site Info" links above. Results are not yet available over the Web, but should be later in the summer.

Presently we distribute data from three sites:

The CMJV data are contributed by Jim Mitchell of Crazy Mountains Joint Venture. We expect to add data from two new sites near Anchorage later this year, and also distribute data collected by FAA receivers in other parts of Alaska.

GI Geodesy Lab

The Geodesy Lab at the University of Alaska Geophysical Institute is an active research group consisting of Dr. Jeff Freymueller, a soon-to-be-hired post-doctoral researcher, and students Hilary Fletcher and Dörte Mann. We are involved in a number of crustal deformation projects aimed at measuring and understanding active tectonic processes, both in Alaska and elsewhere. Click! More information is available about our projects and exciting student opportunities!
