Lamont-Doherty scientist Timothy Crone is at sea off the Northwest U.S. coast, dropping sensors into the deep ocean as part of a major initiative to better understand oceans, climate and plate tectonics. You can watch a live video feed from the robotic vehicle ROPOS and see it deploy instruments and take samples from 4500 feet down on the seafloor.

Scientists are in the early stages of building a fiber optic network on the seafloor for observing, in real time, deep-sea hydrothermal vents---places where super-heated water and minerals spew from Earth's crust offering clues about how life on the planet may have began.

January 10, 2008 ---Zigzagging some 60,000 kilometers across ocean floors, earth’s system of mid-ocean ridges plays a pivotal role in many workings of the planet—from its plate-tectonic movements to heat flow from the interior, and the chemistry of rock, water and air.... -

Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth Observatory and the Earth Institute at Columbia University, recently learned that two-thirds of the seismometers she placed on the floor of the Pacific Ocean were trapped more than 8,000 feet (2500 meters) underwater, it turned out to be an extremely good sign.
