 | The Yeti Crab
Video footage taken by the submersible Alvin is the first ever seen of this newly discovered family of crabs. It shows a 6-inch male "Yeti" crab. Shadows in the video are cast by the submersible.

 | Ice-Tethered Profiler Deployment
WHOI researchers deploy a new instrument, an Ice-Tethered Profiler (ITP). The ITP has a small yellow surface capsule that dangles an anchored 800-meter (2,265-foot) line through a hole in an ice floe. An instrument travels up and down the line daily, measuring water pressure, temperature, and salinity. Data are transmitted via satellite to WHOI, along with a GPS location of the instrument on the drifting floe. The ITP has enough battery power to last for three years, barring a breakup of the ice floe or polar bear vandalism.

 | What are Deep-sea Corals?
Many think corals thrive only in tropical waters, like the Great Barrier Reef or the Florida Keys. Biologist Rhian Waller of WHOI talks about deep-sea corals, found in dark, cold seas.

 | Lights, camera, action at the Juan de Fuca Ridge
The deep-sea light post was used in tandem with a high-definition video camera from the University of Washington to capture images of octopi, tubeworms, crabs, and super-heated fluids flowing from hydrothermal vents and crevices.

 | Coastal Upwelling
Strong winds blowing along certain coasts can promote a phenomenon known as coastal upwelling. The waters off California, Peru, and western Africa?where upwelling provides abundant nutrients?include some of the most productive fisheries in the world.

 | A Mess of Physics Near the Shore
The location of sandbars can protect or endanger the face of the beach. As undertow drives sandbars away from the shoreline and further out to sea, waves break further from the shore. When sandbars are pushed closer to shore, waves break closer and run further up the beach.

 | Lava Flow Sequence
This animation shows a possible sequence of how lava flows might erupt on the seafloor and create new ocean crust. It is based on conceptual models and observations derived from collected data, at the East Pacific Rise near 9° 50'N in the Pacific Ocean.

 | How Does an Observatory Work?
When magma rises through Earth's crust to a mid-ocean ridge, ocean observatory sensors detect the ground motion, the spilling lava, and the chemicals spewing from hydrothermal vents. Observations are relayed via satellite back to shore-based researchers, who can command their instruments and a robotic vehicle to make specialized measurements, and then muster an expedition to inspect the eruption firsthand with submersibles or other undersea vehicles.
