The Arctic Ocean is heating from below, a new study has found.
“The strength of heat coming up from below the surface has been as strong as the heat coming down from the Sun,” said the mission’s chief scientist, Jennifer MacKinnon, of the Scripps Institution of Oceanography at the University of California San Diego.
“There’s a reservoir of heat in the Arctic Ocean, well beneath the surface, that historically – when there’s been a lot of ice – has been fairly quiescent,” Dr MacKinnon explained.
The heat is being brought to the surface by surprisingly strong eddies, Dr MacKinnon’s team found. “The strength of [these currents] has been incredible,” Dr MacKinnon said.
Some of these currents were bringing water as warm as 6C to depths shallower than 50m; these are even more dramatic disturbances than the team had expected.
The source of that deep heat is a layer of warm water that is saltier – and therefore denser – than water at the surface.
As dwindling ice exposes more water to the wind, this turbulence could close a vicious circle, accelerating ice melt, the article warns.
This may all be true. But it doesn’t address the bigger question. If that heated water is coming from the depths of the ocean, how did it get down there?
There is no way that humans could heat the deeper waters without first heating the surface.
I think the best explanation would be that the water is being heated by underwater volcanoes.
Most people aren’t aware of this, but the Arctic Ocean contains untold numbers of underwater volcanoes.
Look at the Gakkel Ridge.
Measuring some 1,800 km (1,100 miles) long, the Gakkel Ridge is made up of mile after mile after mile of huge underwater volcanoes. This chain of underwater volcanoes is far mightier than the Alps, which measure “only” 1,200 km (750 mi.) long.
Eleven-hundred-miles long. That’s farther than it is from Seattle to Los Angeles. A planetary-sized hot water heater.
Scientists have found “surprisingly strong magmatic activity in the West and the East of the ridge and one of the strongest hydrothermal activities ever seen at mid-ocean ridges.” Indeed, they’ve found “dramatically” higher magmatism than expected.
Forget your global warming nonsense, that water is being heated by underwater volcanoes.
