NASA eyes the ocean: How the deep sea could unlock outer space

The Christian Science Monitor

“When hydrothermal vents were discovered in 1977, it very much flipped biology on its end,” says Julie Huber, an oceanographer who studies life in and below the seafloor at Woods Hole Oceanographic Institution (WHOI) on Cape Cod. “People knew that organisms could live off of chemical energy, but they didn’t imagine they could support animal ecosystems.”

Geology creates chemical energy: Origin of a massive methane reservoir discovered

Cosmos Magazine

Scientists know methane is released from deep-sea vents, but its source has long been a mystery. A team from Woods Hole Oceanographic Institution may have the answer. Analysis of 160 rock samples from across the world’s oceans provides evidence, they say, of the formation and abundance of abiotic methane – methane formed by chemical reactions that don’t involve organic matter.

Origin of Massive Methane Reservoir Identified

New research provides evidence of the formation and abundance of abiotic methane—methane formed by chemical reactions that don’t involve organic matter—on Earth and shows how the gases could have a similar origin on other planets and moons, even those no longer home to liquid water.

Sentry Completes Its 500th Dive

Sentry Completes Its 500th Dive

WHOI’s free-swimming robot Sentry completed its 500th dive on October 16, 2018, off the Pacific Coast of Costa Rica. The autonomous underwater vehicle has used its sonar systems to help scientists map the seafloor, track the Deepwater Horizon oil spill, locate the voyage data recorder on the sunken El Faro cargo ship, and carry out advanced research on many other missions to help us better understand our ocean and our planet.
