The plume's more southern location, Toomey said, adds fuel to his group's findings, at three different sites along the globe encircling mid-ocean ridge (where 85 percent of Earth's volcanic activity occurs), that Earth's internal convection doesn't always adhere to modeling efforts and raises new questions about how ocean plates at Earth's surface — the lithosphere — interact with the hotter, more fluid asthenosphere that sits atop the mantle.

Slow rifting speeds carve a trough along the divide, while faster speeds leave a raised ridge, just as seen in the ocean.

To study the movement of vent products, the researchers set up sediment traps and current meters near the hydrothermal vents along the East Pacific Rise, an ocean ridge located about 800 kilometers off the southern coast of Mexico and a mile and a half below sea level.

By analyzing the speed of seismic waves generated by earthquakes, scientists have shown that temperature differences deep within Earth's mantle control the elevation and volcanic activity along mid-ocean ridges, the colossal mountain ranges that line the ocean floor.

You will recall that hydrothermal vents are plumes of hot water that spew from rocks and cracks along the ocean floor, especially in regions of sea - floor spreading, such as oceanic ridges and rift valleys.

Biologists were surprised to discover that the ecosystems found on the ocean floor along these mid-ocean ridges, consisting of complex organisms like tube worms, clams, and crabs, were dependent for their food on thermophilic chemosynthetic bacteria, which produced organic compounds using the oxidation of inorganic molecules as an energy source, instead of sunlight.

The study also found that the Southern Ocean Circumpolar Current, which helps determine sea - ice extent, is steered by submerged ridges and canyons along the edge of the Antarctic continental shelf, rather than by global warming or other climatic conditions.

For a long time people thought that ocean pH was regulated ultimately by reactions between deep seawater and sediments, but as Walt Allensworth February 5, 2015 at 3:08 pm, says there are so many black, and clear, vents along the midocean ridges spewing acidic water, that these probably maintain ocean pH instead.

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges.
