Operation Deep Freeze: An aging ship

The Polar Star’s engineering department ensures the ship’s mechanical and electrical equipment is working properly, but the harsh conditions of Antarctica provide many challenges for the aging ship, which has been around longer than many of its crew members.

Operation Deep Freeze: A military operation

The capabilities of the United States military can assist scientific researchers discover more about our planet. One peacetime mission assisting in that realm is Operation Deep Freeze. Operation Deep Freeze is one of the military’s most challenging peacetime missions, as the environment in which the mission is conducted is harsh. Negotiating the frozen seas of the Antarctic region requires specialized equipment and skills, which is where the Coast Guard Cutter Polar Star comes in.

Headed south for the winter: Coast Guard Cutter begins journey to Antarctica

More than 150 Coast Guard men and women embarked on a journey that would take them to the bottom of the world Nov. 30, 2014; bound for a place only a small fraction of the world’s population will ever see. The Coast Guard Cutter Polar Star from Seattle is on an expedition to Antarctica in support of the United States Antarctic Program, which is managed by the National Science Foundation.

Battling lead contamination, one fish bone at a time

Lead. Throughout America’s history, it’s been used in paint, batteries, gasoline and even water pipes. Today, lead contamination in one of the oldest Oakland, Calif., neighborhoods is being neutralized not by more chemicals or hauling away tons of dirt but by mixing ground fish bone into the soil.
