The secrets I find on the mysterious ocean floor | Laura Robinson
Hundreds of meters below the surface of the ocean, Laura Robinson probes the steep slopes of massive undersea mountains. She's on the hunt for thousand-year-old corals that she can test in...
========== Well, I'm an ocean chemist. I look at the chemistry
of the ocean today. I look at the chemistry
of the ocean in the past. The way I look back in the past is by using the fossilized remains
of deepwater corals. You can see an image of one
of these corals behind me. It was collected from close to Antarctica,

so it's got tremendous spatial resolution. The overall features are extremely
