Sentence examples for At seafloor from inspiring English sources
Compressed gas is used to maintain the sample at seafloor pressure before and during sample withdrawal onboard ship, allowing subsampling without degassing the fluid remaining in the sampler.
We describe recent advances in the development of enhanced (or engineered) hydrothermal systems, numerical models describing multiphase flow, and real-time monitoring of hydrothermal flow at seafloor observatories.
Because there is no evidence of major glaciations in the Jurassic, any global sea level change must have been due to thermal expansion of seawater or plate tectonic activity (such as major activity at seafloor ridges).
New oceanic crust (and part of Earth's upper mantle, which, together with the crust, makes up the lithosphere) is formed at seafloor spreading centres at these crests of the oceanic ridges.
On the other hand, weathering of ultramafic rocks exposed at seafloor below 150 °C and hydrothermal circulation at high water/rock ratios provide Mg into seawater (Snow and Dick 1995).
The four stations at C node are set at seafloor depths between 3,500 and 4,400 m, while 16 stations at other nodes are positioned at depths between 1,900 and 2,500 m.
The current electrodes were fixed at the seafloor (C1) and at sea level (C2).
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.
10 In the letter, Odum argued that drilling muds—slurries of clay and other minerals mixed with water or oil that modulate oil flows in the pipe connecting the wellhead at the seafloor to the drill rig at the surface would be heavy enough to contain a low-pressure blowout.
A new gas-tight isobaric sampler for the collection of hydrothermal fluids venting at the seafloor has been designed, constructed, and tested at a ridge-crest vent site.
In the North Atlantic the temperature decreases slowly toward the bottom from a value of about 41 °F (5 °C) at roughly 3,000 feet (900 metres) to about 36.5 °F (2.5 °C) at the seafloor.
