 I was in the middle of the Atlantic Ocean when it happened. There was a sudden jolt and our submarine crashed on the seafloor. We were in total darkness. That's Dr. Dijana Figueroa, a marine biologist and STEM teacher, talking about a deep sea dive she'll never forget. It's funny. When I was a kid, I was afraid of the ocean. And there I was, two miles below the surface. But as a scientist, you prepare for that. Using our training and a little creativity, we fixed the sub and finished our experiments.
