"Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That each person who serves, or has served, as a member of a United States expedition to Antarctica between January 1, 1946, and a date to be subsequently established by the Secretary of Defense shall be presented a medal with accompanying ribbons and appurtenances, under regulations to be prescribed by the Secretary of Departments under whose cognizanze the expedition falls, such regulations to be subject to the approval of the Secretary of Defense...
The ribbon of the Antarctica Service Medal is elaborate in its symbology. The outer bands of black and dark blue comprise five-twelfths of the ribbon's width, representing five months of antarctic darkness; the center portion, by its size and colors - grading from medium blue through light blue and pale blue to white - symbolizes seven months of solar illumination, and also the aurora australis.
Although the former rigors and dangers of antarctic exploration have largely been banished by technology, the words on the reverse of this medal are yet a wise injunction to those who go to the Antarctic: COURAGE - SACRAFICE - DEVOTION. "
Been there, done that, saw green clouds, got a medal and am going to Panama to learn how to surf. Simple as that.
