In temperatures that can plummet to -40 degrees Fahrenheit, ICEX puts Navy submarines and their personnel through extreme training. Navigating the Arctic waters is no easy feat, as the ice above changes the acoustics underwater, and prevents an easy surfacing. But the Navy isn't alone: ICEX involves more than 200 people from multiple nations, all of whom stay at a temporary ice camp atop a floating ice sheet. The team gathers scientific data, too, analyzing the thickness of the Arctic ice and the surrounding environmental conditions.
