Alert
As of midnight, December 20, 2024, the U.S. government is experiencing a lapse in appropriations. Until the situation is resolved, please refer to OPM.gov website regarding the status for federal employees. We expect the U.S. Antarctic Program to remain operational under our contractor for the foreseeable future. Should the situation change, we will post additional information on this website when it is legally permissible to do so.
 

When dialing from outside the U.S., replace the 011 or 1 prefix with the appropriate international call access code for the country in which you are located. For more country code information, view the International Dial Codes.
