Traveling to the deep ocean, however, is an entirely different—and arguably more dangerous—challenge. It’s an otherworldly place, with crushing pressures, bizarre life, and a trove of hidden scientific secrets waiting to be revealed. To study its inner workings, ocean scientists must descend to its furthest reaches, either via robotic vehicles or by braving its depths in person within the cramped quarters of a research submarine. Studying midocean spreading centers offers a window into that deep world, provided scientists can get there in the first place. To WHOI marine microbiologist Julie Huber, the idea that life exists deep within the crust make perfect sense.
