Sentences with phrase «from shallow region»

This is similar to the bacteria found in oil reservoirs and contaminated soil, which could mean that the bacteria migrated down from shallower regions rather than evolving inside the crust, the team say (PLoS ONE, DOI: 10.1371 / journal.pone.0015399).

Not exact matches

This interaction may occur anywhere in the ocean, in particular in regions where surface - gravity waves interact as they reflect from continental shelf breaks, where the deep - sea suddenly faces a much shallower shoreline.

Although the South America plate exhibits a chain of active volcanism resulting from the subduction and partial melting of the Nazca oceanic lithosphere along most of the arc, these regions of inferred shallow subduction correlate with an absence of volcanic activity.

A throng of reef - dwelling organisms live on the edge of the Gulf of Mexico's continental shelf some 200 kilometers offshore, from corals in the shallower regions to sponges, sea fans and other soft corals, and numerous fish species in the deep.

By analyzing seismic wave data from monitoring stations around the region, seismologists concluded the North Korean blast had come from shallow depths, no more than a few kilometers within the mountain.

The broader region is vulnerable to earthquakes from multiple sources, including deep earthquakes within the subducted Juan de Fuca plate, offshore megathrust earthquakes on Cascadia subduction zone and the shallow crustal earthquakes within the North American Plate.

But it says that deeper reef environments — 40 metres to 150 metres below the waves — could serve as a refuge for species driven from the shallows, although more research needs to be done to establish a role for these regions.

The laid - back eco-hotels in the seaside towns of Toco and Grande Riviere make a perfect home base from which to explore the area, which is also known for «river liming,» the Trinidadian tradition of de-stressing by eating, drinking, and chilling in one of the region's many shallow mountain - fed rivers.

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.

With time, however, the drying of the nonprecipitating region induces a reversal of the shallow circulation, drawing the flow at low levels from the precipitating to the nonprecipitating region.

Presumably, the theorized massive movement of heat from shallow surface waters to deep regions of the Atlantic and Southern Oceans remains an active process.

Oregon State University will generate computer models that will enable researchers to interpret modern - day releases of methane into the atmosphere — or methane fluxes - and reconstruct past episodes of methane flux in gas hydrate - bearing regions from shallow geochemical data.

Prof Wadhams is co-author of the controversial Nature paper which calculated the potential economic costs of climate change based on a scenario of 50 Gigatonnes (Gt) of methane being released this century from melting permafrost at the East Siberia Arctic Shelf (ESAS), a vast region of shallow - water covered continental crust.

This is still very early science, and we have some estimates of what may happen to those from modelling studies, from looking at the way in which the heating of the very upper layers of the Arctic Ocean is transferred down through the depth of the ocean - even in these relatively shallow Arctic shelf regions - and then into the sediments that would allow the methane hydrates to destabilise.
