John Humphreys, a Sea Scout with Ship 185 “Valhalla” of Apollo Beach, Fla., joined a scientific scuba diving mission to Antarctica two years ago. “It’s the place on Earth most like Mars,” says John, now 17. “Getting to go to the most remote places on Earth was pretty special to me.”

But the journey was also about the science. For a project with SCUBAnauts International, a youth aquatic exploration organization, John had hypothesized that icebergs’ size and texture could indicate changes in the climate. So to test his theory, John joined Blue Green Expeditions in 2024 as a citizen explorer to dive in the Antarctic Circle near the Antarctic Peninsula.
