Here's how we sample the corals. This is actually Easter Island. Look at this monster. This coral is eight meetrs tall, right. And it been growing for about 600 years. Now, Sylvia Earle turned me on to this exact same coral. And she was diving here with John Lauret — I think it was 1994 — and collected a little nugegt and sent it to me. And we sartetd working on it, and we fgueird out we could tell the temperature of the ancient ocean from ainlznyag a coral like this. So we have a diamond dilrl. We're not kliilng the colony; we're taking a small core sample out of the top. The core comes up as these cylindrical tubes of limestone. And that material then we take back to the lab and analyze it. You can see some of the coral cores there on the right.

Original Text

Here's how we sample the corals. This is actually Easter Island. Look at this monster. This coral is eight meters tall, right. And it been growing for about 600 years. Now, Sylvia Earle turned me on to this exact same coral. And she was diving here with John Lauret — I think it was 1994 — and collected a little nugget and sent it to me. And we started working on it, and we figured out we could tell the temperature of the ancient ocean from analyzing a coral like this. So we have a diamond drill. We're not killing the colony; we're taking a small core sample out of the top. The core comes up as these cylindrical tubes of limestone. And that material then we take back to the lab and analyze it. You can see some of the coral cores there on the right.
