Sentences with phrase «sea floor currents»

Then the team's computer simulations showed that eddies could trigger changes in sea floor currents matching the patterns measured by the instruments, with the best correlation occurring when the effects on deep - sea currents happened 8 days after the eddy passed overhead.

Not exact matches

According to the study, most of the highly toxic benzene and toluene in the oil were transported away in deep currents, along with other entrapped petroleum compounds that affected organisms on and near the sea floor.

Pushed by the natural motion of wind and ocean currents — often over long distances — the litter is present in oceans worldwide, as well as in sea floor sediment and coastal sands.

Byssal threads that are too weak to withstand currents and other forces cause mussels to dislodge and fall to the sea floor.

But most scientists presume that the environment on the sea floor is fairly stable: Temperatures hover near freezing, darkness reigns, and currents are languid and steady.

The currents caused by large, swirling eddies at the ocean's surface may reach all the way to the sea floor, a new study suggests.

«These results will have wider reaching implications, such as how we map the circulation of the world's oceans in the past, which are affected by how quickly the sea floor is moving up and down and blocking the path of water currents,» said Hoggard.

Recent methane measurements at Terceira Island, Azores, Portugal and Tae - ahn Peninsula, Republic of Korea (See http://www.esrl.noaa.gov/gmd/dv/iadv/index.php) in the context of outlier data points over the last decade at sites such as Storhofdi, Vestmannaeyjar, Iceland, and reports of methane releases from the Arctic seabed, tell us that at current levels of AGW, the Earth's sea - floor methane systems are not stable.

Ocean currents that may carry large amounts of heat are not calculated into the GCM, and thus we do not have a good estimate of the rate of energy transfer at the boundaries of specific sea - floor methane systems.

Topics include Earth's Interior, Heat Transfer & Convection Currents, Continental Drift, Sea - Floor Spreading, Theory of Plate Tectonics, Plate Tectonic Boundaries, and more!

Additionally, seagrass ecosystems help filter, clarify and oxygenate seawater, stabilize sea floor sediments, slow strong currents, and reduce coastal erosion.

Flat stretches of sea floor offer no nooks in which to hide or lay eggs, less surface area providing a home for algae, invertebrates, and other potential food sources, and no eddies in which fish can take shelter from strong currents.

Using a computer model of wave - induced current stresses, the team estimated how powerful currents would need to be for forces they exert at the sea floor to exceed a «critical force» that triggers sediment suspensions and could lead to underwater mudslides.

Ranging from small - scale turbine units on the sea floor to large - scale turbines on vertical towers or suspended from boats, tidal current exploitation technology is still very much in the infant stage of development.

We know heat propagates below 700m by conduction, currents, sea floor hyrovents, sporadic localized funneling episodes etc..

You don't think perhaps that celestial cycles just might have an effect on magma currents (yes just like the ocean, just slower) and that effect translates to changes in sea - floor seismic activity from time to time?

I would point out to Nice one that the sea - floor seismic heating we are pointing to (some geo - physics papers on this) is IN ADDITION TO propagation from the 0 - 700m layer via conduction and currents.

Third, as first observed in the 1990s, the area is vulnerable to a regional ocean current, ushered in by the shape of the sea floor and the proximity of the circumpolar deep current.

The words «sea level» are misleading: for a range of reasons — from gravitational anomalies on the sea floor to the intrusion of a warm current, or a pattern of high winds — the sea's contours ripple up and down imperceptibly around the planet.
