洋流如何塑造海洋微生物组

Ocean microbes keep the planet healthy by cycling nutrients and capturing carbon, but a detailed and precise map of where they live had never been made—until now. BY STEPHANIE DEMARCO, PhD Wind howls and waves roar as storms rage over the open ocean. But even as gusts reach hurricane strength and swells rise as high as six-story buildings, the violent effects of these storms only reach about 500 meters beneath the surface. “The ocean's four kilometers deep, so there's a whole lot more going on,” said Bethany Kolody, a microbiologist at the University of California, Berkeley (UC Berkeley). Beneath that half kilometer depth, the ocean is quiet. Winds and waves no longer dictate how the water moves; density does. …
