Sentences with phrase «seafloor movements»

In 2011, the IEEE, a professional association for electronics engineers, highlighted the risk to the global economy from the proximity of submarine cables carrying international commercial data at certain «choke points» — allowing sabotage or seismic seafloor movements to take out many cables at once.

The earthquakes at Axial Seamount are small and the seafloor movements gradual and thus can not cause a tsunami.

GPS and acoustic data reveal very large seafloor movements associated with the quake directly above the focal region.

«We'll also be closely investigating the effects of other processes within the subsurface, such as groundwater flow and seafloor movement due to aftershocks.

Not exact matches

By combining laboratory experiments, computer simulations and real - world observations, researchers discovered that the horizontal movement of sloped seafloor during an underwater earthquake can give tsunamis a critical boost.

There they would be able to observe several important processes — the formation of new seafloor, volcanic eruptions, the movement of nutrients from deep to shallow waters, and earthquakes.

«We installed seafloor stations to monitor crustal movements offshore directly.»

The selective extinction of large - bodied animals could have serious consequences for the health of marine ecosystems, the scientists say, because they tend to be at the tops of food webs and their movements through the water column and the seafloor help cycle nutrients through the oceans.

Possibilities include the creation of de facto marine reserves as fish cluster under the fields of floating turbines, loss of birds that fly into the turbines, entanglement of sea creatures in cables used to tether the turbines to the seafloor, and disruption of movement patterns of underwater animals.

And over millions of years, the movement and collisions of tectonic plates have lifted some of these seafloor sulfide mounds onto land, where they have been discovered and mined.

Most important, the work simulated the movement of dye — not viscous oil — injected in the upper layers of the ocean — not the deep seafloor — for a total of two months — not the ongoing no - end - in - sight disaster.

«What keys the animals might use to time coordinated movement when at the seafloor, which would lack light at many depths, is... unknown.»

In a series of models, Grilli and his former doctoral student Jeff Harris worked backwards in time to recreate the movement of the seafloor from the earthquake and concluded that an additional movement underwater about 100 kilometers north of the earthquake's epicenter must have occurred to propagate the large waves that struck Sanriku.

Postscript: Scientists at the Naval Research Laboratory, analyzing seabed currents and mud movement after the passage of Hurricane Ivan in 2004, have concluded that the underwater turbulence from hurricanes could be severe enough to cause mudslides and possibly imperil pipelines on the seafloor in shallow regions of the Gulf of Mexico.
