Undersea

A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions.

Germany and Norway on Thursday officially launched an undersea power cable between the two countries in a project that aids Europe’s effort to shift from fossil fuels to renewable energy.

It's like an undersea meadow and turtles, rays and sharks over that are like flying creatures.

It’s no longer news that on April 20th, the catastrophic explosion of an offshore rig sent an undersea gusher of oil boiling to the surface of the Gulf of Mexico off Louisiana. Or that winds, tides and time have overwhelmed efforts to contain a slick the size of Cyprus, spreading globs of emulsified goo to the very edges of the tender marshes and bayous of Plaquemines Parish, and onto the barrier Chandeleur Islands.

The bathysphere is a new technology for undersea travel.

Visitors to New York's American Museum of Natural History are not likely to forget their first encounter with the giant blue whale suspended from the ceiling of the Museum's Hall of Ocean Life. But the beloved, 30-meter long icon was anatomically incorrect until a recently-completed renovation to the model, part of the entire Hall's refurbishment, put things right. The renovated exhibition hall, like the whale, better depicts the undersea world, and better reflects the Museum's dedication to conservation.

The volcanic vents were discovered five kilometers down near the bottom of Cayman Trough — an undersea trench south of the Cayman Islands. Expedition co-leader Jon Copley, a marine biologist of the University of Southampton in England spoke to us via Skype.

It is not known just what action will be taken against the captain of the undersea boat.

"You're right!" she cried. "I'm sure you are." Twenty reasons come back. An undersea tunnel to the little island.

The Sediment (SNAP-7E) Density Meter (an underwater rocket) has been developed to investigate to an ocean-bottom depth of 11 sedimentary feet. Sea Lab I, the Navy’s new undersea laboratory, complete with observation porch and garage, should become safe to operate at the 200 foot level.
