It aims only to drill down to 1, 400 feet beneath the seafloor, then plug and seal the hole for reentry next year.
FORBES: After Mishaps, Shell Dials Back Arctic Oil-Drilling Plans
As the bacteria produced oxygen, the two compounds reacted to form iron oxide, which precipitated onto the seafloor in great layers of rust.
Even farther afield is "The Abyss, " a sci-fi underwater adventure that takes place on a high-tech drilling rig that sits on the seafloor.
About 2, 400 barrels of oil had escaped through the well bore, seeped up into the rock, then escaped through fissures in the seafloor.
They will continue to explore through and are also testing methods to measure the rate that gas rises from seeps in the seafloor.
Hurricane Katrina had turned Mars into a pile of steel spaghetti, dumped its 100-ton derrick under 3, 000 feet of water and mangled pipelines on the seafloor.
Linked to GPS devices and sonar positioning beacons on the seafloor, the thrusters can keep the ship in a steady position even in 95mph winds.
Tethered to the seafloor 130 miles southeast of New Orleans in 2, 900 feet of water, Mars was built to withstand 71-foot waves and 140mph winds.
Unlike in the Gulf of Mexico, where big fields are produced by floating platforms tethered to the seafloor, in iceberg alley you need sturdier gear.

In addition, he said, blowout preventers the giant emergency shut-off valves that failed on the Deepwater Horizon are located aboard drilling rigs in shallow-water operations, not on the seafloor.
During that time the ship and its instruments mapped 5, 970 square miles (15, 460 square kilometers) of seafloor, an area larger than Connecticut, according to the NOAA release.

Finally, as the lights from his Deepsea Challenger submersible set the seafloor aglow, Cameron came to rest at one of the most isolated spots on the planet.
They also congregate around mountains rising from the ocean seafloor.
The design of the new observatory is based in part on two larger networks of seafloor monitors off the coast of British Columbia's Victoria Island, named VENUS and NEPTUNE.
Video shot by the robotic submarines (a.k.a. remote operated vehicles or ROVs) seems to indicate that oil is leaking from three spots in a pipe that is laying on the seafloor.
The primary culprit behind the explosion appears to be the blowout preventer, a two-story-tall stack of valves on the seafloor that was built by Cameron in 2001 and designed to guillotine shut an out-of-control well.
Even a relatively small amount of gas a can cause big problems because a gas bubble will expand massively as it moves from high pressure at the seafloor to lower pressure at the surface.
This causes cracks to appear in the ocean seafloor -- this is what we think, " explains Buckland, adding "So you can measure what's happening to the landmass of Greenland by looking at the sea.
