The Nautilus is a research vehicle operated by the Ocean Exploration Trust, a nonprofit founded by Robert Ballard, one of the people who helped us find the Titanic. It conducts scientific research and offers live video and audio streams to those of us who are unable to come along. This year, it’ll journey along the western part of North America, from British Columbia to the Hawaiian islands. Right now, it’s exploring the Lōihi Seamount, an active underwater volcano near Hawaii. Next, it’ll head to the Papahānaumokuākea Marine National Monument, one of the largest conservation areas protected by the US.

My family and I visited the Mystic Aquarium in Connecticut which had a live link with an Ocean Exploration Trust crew where you could ask the researchers questions as they went about their work. These streams won’t replace the interactivity, but they are still useful in the classroom.
