Final answer:
In 1955, the Seabees were deployed to Antarctica to prepare for the International Geophysical Year by constructing infrastructure for scientific research.
Step-by-step explanation:
Seabees, the construction battalions of the United States Navy, were deployed to the continent of Antarctica in 1955 as part of Operation Deep Freeze to prepare for scientific research. This operation played a pivotal role in establishing the infrastructure necessary for the International Geophysical Year of 1957-1958. The Seabees' mission included constructing research stations, airstrips, and other facilities necessary to support scientific endeavors on the continent.
This deployment was part of the U.S. Navy's Operation Deep Freeze, which supported scientific research activities in Antarctica. The Seabees played a crucial role in constructing and maintaining the infrastructure necessary to support scientific missions in the challenging Antarctic environment.
