The mid-ocean ridge is the most extensive mountain chain on Earth

And we can’t figure out what is heating our seas?

“The mid-ocean ridge is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying in the deep ocean,” according to the National Oceanic and Atmospheric Administration (NOAA).

“The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).”

“The ridge system forms the longest and largest mountain range on Earth, winding its way between the continents,” NOAA continues

“Despite being such prominent feature on our planet, much of the mid-ocean ridge system remains a mystery. While we have mapped about half of the global mid-ocean ridge in high resolution, less than one percent of the mid-ocean ridge has been explored in detail using submersibles or remotely operated vehicles.”

The Mid-Atlantic Ridge, which is only a part of the mid-ocean ridge, extends for about 10,000 miles (16,000 km) in a curving path from the Arctic Ocean to near the southern tip of Africa. The ridge is equidistant between the continents on either side of it.

More than forty thousand miles of underwater volcanoes – who knows how many are active? – spewing out red-hot magma (as much as 2000 degrees F), and we can’t figure out what is heating our seas?

Wake up, people. We are being played.

  1. Come on – how could this possibly have anything to do with climate when there are 420 molecules of CO2 and 2 molecules of Methane in every MILLION molecules of ordinary air ???

  2. The mid-ocean ridge is the most extensive mountain chain on Earth… and the volcanoes of Iceland include a high concentration of active ones due to Iceland’s location on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot. Over the past 500 years, Iceland’s volcanoes have produced ONE THIRD of the TOTAL GLOBAL LAVA OUTPUT.

    Bárðarbunga 2014–2015 [like Cowabunga only larger]
    Lava flow was between 250 and 350 cubic metres per second and came from a dyke over 40 km long.[13][14] An ice-filled subsidence bowl over 100 square kilometres in area and up to 65 metres deep formed as well.

    Lava fountains observed during Mount Vesuvius’ 1779 (only 240 years ago) eruption are believed to have reached at least 3,000 m (9,843 ft). There is nothing new under the sun… these days are comin’ again… we’re way past due.

  3. Oh course we are being played and in more ways than one. They know exactly what is heating our oceans and it is NOT “global warming” (aka: the “climate emergency”). Honestly, I have (and have had for some time) the feeling that our planet is going to come unglued. Feelings alone do not suffice but now the science is coming into line with my feelings and it’s becoming rather unnerving. Sadly, many don’t have a clue and will be caught unprepared.

  4. Much more exploration of these ocean ridges is needed.
    Very difficult to evaluate how much heating of oceans is cause by vents and magma.
    Current active Icelandic vents on land ,would suggest there must be SOME current activity in the sub-sea vents both sides of Iceland.
    After all, Europe and N America are pulling apart.

  5. Robert, Surely it’s an oversight. You missed quoting the 1st paragraph in the body of the article below the NOAA image, to wit,: “The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).” Without this paragraph you article is a bit lacking. one might ask, “How would mountain ranges be heating our seas?” Unless those mountain ranges are “…a continuous range of underwater volcanoes…” Since a lot of people are merely headline readers, the headline, “The mid-ocean ridge is the most extensive mountain chain on Earth,” says nothing about volcanoes or “…heating the seas…” Just sayin’!

  6. 80 or so % of the planets hidden by water.
    a lot of that pretty deep.
    we know stuff all about the majority but they refuse to even talk about the high chances of any ocean depth warming being natural volcanic and try n push the co2 heated the top of the oceans then it sank down
    whaaaat? what brain chain of garbled inanity manages not to laugh when claims like that are made by some wanna be famous twit from a gang-green clique

    • Agreed. The problem with the idea that CO2 heated the oceans is that warmer water actually expels CO2. The warmer the oceans, the more the CO2 is outgassed. As for the warmth sinking, this just does not happen – convection works in the opposite direction – cold sinks, heat rises. So the heat in the oceans is actually coming from the BOTTOM of the oceans, where the water is being heated by these geological sources, then convecting to the top.

  7. Robert, it seems “The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).” is missing from this blog post. It’s the first paragraph in the text of the NOAA article.

  8. Lol
    Unfortunately volcanic activity is not increasing but atva steady rate
    Yet the planets temp has not been steady but instead increasing which seems to negate thecptemiss of this article
    In Earth Science 1 class you would all get Ds

  9. I have read somewhere that the ocean has inertia to keep its warm during major warming in 20th century, and even though the cooling has just started, say in 2018, the ocean water retained its heat for maybe 100 years…. yes of course it probably getting heat from those mountain chain as well,,,,
    btw, the remaining heat from ocean , and the cooling of atmosphere due to cooling sun is ideal for lots of rain and sun, imho.
