The challenging rescue operation launched after a Russian ship became trapped in Antarctic pack ice in December shows the inherent risks facing the frozen continent's burgeoning tourist industry, experts say. Antarctica represents one of the last frontiers for adventurous travelers, an icy wonderland of glaciers, emperor penguins and seemingly endless white expanses.
The Australian Maritime Safety Authority (AMSA) confirmed Wednesday that the entrapped Antarctic ships, the Akademik Shokalskiy and the Xue Long (Snow Dragon), have broken free from the ice in Antarctica and are no longer in need of assistance.
