Deep below the Arctic sits a ridge that splits the ocean roughly in half: The Amerasian basin sits on the North American side, whereas the Eurasian basin lies north of Europe and most of Asia.

The coolest point beneath the ridges was found near the lowest point, an area of very deep and rugged seafloor known as the Australian - Antarctic discordance in the Indian Ocean.

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.

«Ultimately, we'd like to go to mid-ocean ridges located deep in the southwest Indian Ocean and the mid-Atlantic,» says Susan Humphris, the WHOI geochemist overseeing the upgrade.

«Ocean ridges are the most dynamic places on our planet, and this is the first cabled observatory that goes out to one,» says oceanographer Peter Rona, who uses NEPTUNE to study the dynamics of the deep - sea volcanoes from his lab at Rutgers University in New Jersey.

«This is very exciting in terms of its implications for the deep ocean and how mid-ocean ridges work,» he told New Scientist.

Europa has a global ocean locked away beneath a crust of ice; deep below, the moon's internal heat might create hospitable conditions, akin to hydrothermal vents at the bottom of the mid-Atlantic ridge and East Pacific Rise on Earth.

The new find confirms that the ancient lavas formed at midocean ridges and found throughout deep ocean basins are by volume the largest ecosystem on Earth, scientists say.

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.

Methane Cold Seeps Methane cold seeps are similar to the more famous black smokers in that they form isolated ecosystems as oasis in the deep ocean, but are lower temperatures and form away from mid-ocean ridges.

PROVIDENCE, R.I. [Brown University]-- 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.

The bathymetry of the ocean bottom is marked by fault block ridges, abyssal plains, ocean deeps, and basins.

So it might take several hundred years for the deep oceans (where many of the volcanic vents and mid-ocean ridges are) to warm even a single degree.

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.

Observations and numerical modeling reveal large fluctuations in the ocean heat available in the adjacent bay and enhanced sensitivity of ice - shelf melting to water temperatures at intermediate depth, as a seabed ridge blocks the deepest and warmest waters from reaching the thickest ice.

This ridge completely isolated the deep North Atlantic from other oceans, like a giant bathtub on the ocean floor.
