Sentences with phrase «through hydrothermal vents»

For the ocean to be liquid there must be substantial sources of heat — from tidal heating based on the shape of its orbits, or from heat emanating from radioactive decay and entering the ocean through hydrothermal vents.

The entire ocean volume circulates through hydrothermal vents about every 40 million years.

Lead scientist Jeffrey Hawkes, currently a postdoctoral fellow at Uppsala University in Sweden, directed an experiment in which the researchers heated water in a laboratory to 380 degrees Celsius (716 degrees Fahrenheit) in a scientific pressure cooker to mimic the effect of ocean water passing through hydrothermal vents.

The new study determined that the methane contained in the fluid leached from sub-seafloor rocks, and was not formed through hydrothermal vent circulation, as had been previously thought.

In Pescadero Basin, however, hydrothermal - vent fluids pass through thick layers of seafloor mud.

Geysers and deep - sea vents are hydrothermal phenomena in which water, heated and pressurized by molten rock, is released through vents at the land surface or into the oceans.

The geysers through which this water emerges are known as hydrothermal vents.

The unusual changes in currents may help explain how the larvae of the heat - loving creatures living around hydrothermal vents are dispersed through long stretches of near - freezing waters to reach other warm havens, says Adams.

One of the most prevalent theories as to how life evolved on Earth is through chemical reactions at deep sea hydrothermal vents.

From 1977 through 1979, Alvin made a series of dives to further investigate the nature of these hydrothermal vent communities.

Water, salts, organics, and methane make their way from the hydrothermal vents on the ocean bottom to the surface through cracks in the icy crust, erupting as geysers.

Before whale falls were well documented, it was thought that this type of biodiversity was only seen at cold - seep sites and hydrothermal vents, where hydrogen sulphide and methane naturally escape through the sediment.

Various geophysical techniques have been employed in efforts to determine the heat output from hydrothermal vent fields4 — 9; however, the magnitudes of the heat and chemical fluxes through these systems remain uncertain.

But like the hydrothermal vents, cold seeps can support high densities of specialized life forms through a process called chemosynthesis.

The communities of bacteria around deep sea volcanic (hydrothermal) vents survive by converting highly toxic hydrogen sulfide into food through chemosynthesis much like surface algae convert sunlight to food via photosynthesis.
