What does a frozen sea look like from under the water? Well, researchers and scuba divers from Massey University found out when they dropped a GoPro under the large sheet of ice. It's beautiful and almost otherworldly. The scientists hope to learn more about the changing climate and they say Anchorage, Alaska is a great place to start.
