Transcript for New daring missions will explore never-before-seen parts of the ocean
underwater mission to explore parts of the ocean that no one has ever seen before. Will reeve, it looked like an amazing opportunity. It was incredible. They say we know more about outer space than we do about the oceans but one research group is trying to change that by funding these daring expeditions to explore parts of the ocean that we've never seen before and I was lucky enough to join them on a dive to the bottom of the atlantic which I must say looks a lot like outer space. 30 miles off the east coast of Florida, alutia is exploring the open ocean. The nearly 200-foot-long vessel operated by ocean X has discovered new species and traveled to new depths. It's a critical time for the ocean. It's critically endangered. I want them to think about the grandeur and beauty of the oh and how important it is to human life. Reporter: Now, "Gma" is joining them on their latest mission. Exploring a deep sea coral reef in the atlantic looking for clues about the ocean's health. Crucial to the mission is nadir, an eight-ton submersible vehicle capable of withstanding thousands of pounds of pressure. The reef more than 1,000 feet below us right in the middle of the gulf stream. The powerful current that could push us off course if we don't find our target in minutes. Whoa. Ready to go, guys? Yeah. All right. Let's do it. Reporter: We're lowered in and the mission begin, the power of the atlantic all around. Beneath the surface, a so real calm as nadir dives into the abyss. What do we expect to see? After fighting the gulf stream current we find what we came for, lafilia coral blanketing the floor looking like another planet 1500 feet down. Destructive fishing practices can damage this habitat but this area is remarkably healthy. They're glowing their natural white. The reef teeming with life, fish, crabs, even sharks and after nearly three hours, it's time to climb out of the darkness to the recovery team. My mission was part of oceanx's broader initial tough explore the Florida reef tract to determine its health and I was told I was 1 of only 20 people on the planet to see that specific spot in the ocean which is a real honor and it really blew me away, the pressure down there and we put a coffee cup on the side of the submersible to demonstrate the pressure. It started out as a normal coffee cup. Ended up like this. Oh, come on. Yet you were fine, not even wearing scuba gear. I didn't even wear shoes. Wow, incredible experience. Thanks for bringing that to us.
