Victor Vescovo is a pioneer.

He was the first person to visit the deepest point of every ocean. He also was one of the first people to see the wreckage of the USS Johnston, a U.S. Navy destroyer that sank in 1944 during the Battle of Leyte Gulf, which was the largest naval battle of World War II.

And though he’s shared those sights with the world — including in a series on Discovery+ — he’s still not done.

Recently, the St. Mark’s School of Texas alumnus posted some colorful images on his Twitter account. They are sonar maps of “some massive features lurking in the depths.”

The maps come from research done by the crew of the Pressure Drop, a vessel that has been roaming the Bering Sea and North Pacific over the past month. Researchers are trying to learn more about plate tectonics, Vescovo says in the tweet.
