In this segment we travel through Tracy Arm fjord to visit South Sawyer Glacier, an area seeing significant recession of ice. More and more glacier-carved waterways like Tracy Arm are growing larger as ice continues melting away. As land/sea ice melt, darker soil/rock are exposed that absorb more solar energy that help to speed up the melting process. A natural process of glaciers meeting the open sea is highlighted by dramatic "calving" seen from our ship where house/building-sized chunks of decades old ice break and fall into the bay. This infusion of cooler water into the Arctic region may soon disrupt global ocean/weather patterns with far reaching effects.
