Deepwater Glacier Bay NP 2016

Red tree corals are a focal point of the Deepwater Exploration of Glacier Bay National Park Expedition. These corals have been shown to be the foundation of diverse deepwater communities in Alaska. And can occur as shallow as 6 meters. Here several fish and urchins congregate around a large red tree coral.
