Oh, and just noticed that SOTT has the article up too, but with a different picture.

US scientists discovered two giant whirlpools in the Atlantic Ocean, off the coast of Guyana and Suriname. It became a sensational discovery because this part of the ocean has been studied thoroughly, and no one expected anything like that to appear in the area. More importantly, no one can understand where the whirlpools came from and what surprises they may bring to people.

According to Brazilian scientist Guilherme Castellane, the two funnels are approximately 400 kilometers[240 miles] in diameter. Until now, these were not known on Earth. The funnels reportedly exert a strong influence on climate changes that have been registered during the recent years.

"Funnels rotate clockwise. They are moving in the ocean like giant frisbees, two discs thrown into the air. Rotation occurs at a rate of one meter per second, the speed is sufficiently large compared to the speed of oceanic currents, on the border hoppers is a wave-step height of 40 cm," Castellane said.

Even during the dry months, when the movement of oceanic currents and the flow of the Amazon River practically comes to a standstill, the funnels do not disappear. Therefore, the nature of the funnels does not depend on the flow of water, which one of the world's biggest rivers brings into the ocean. The natural phenomenon, which creates the whirlpools, is unknown to modern science.

As a matter of fact, the phenomenon of giant whirlpools in the World Ocean is not new to science. In most cases, the craters, or rings, as scientists call them, are formed as a result of so-called vertical currents. The latter, in their turn, appear because of differences in water density which appear because of difference in temperatures of water layers. It is an open secret that cold water is thicker and heavier, so it goes down, underneath the masses of warm water, which is lighter. This is the reason why warm currents in the World Ocean always flow closer to the surface, whereas colder currents flow closer to the bottom.

However, such movement of water may not always depend on the difference of temperatures of the water column. The difference in salinity can also be a reason. The mechanism here is the same. The density of saltier water is higher, this water is heavier and it moves closer to the bottom, pushing less saltier water up. This type of vertical fusion occurs frequently in the tropics because high temperatures lead to the evaporation of water from the surface. The salt does not evaporate with water, though. It stays in the ocean, which raises the level of salinity on the upper layer of water. This layer "drowns" and gives way to less saltier waters of the depth.

Such vertical movements of water create giant whirlpools. The whirlpools, tens and even hundreds of kilometers in diameter, may last for months and even years, scientists say. The vertical movement of waters is a slow process, though. Why do those whirlpools exist for such a long time? This is partially the effect of Earth's magnetic field. In addition, marine water contains many charged ions, Na and Cl for example. To crown it all, water molecules are dipoles that are charged both positively and negatively.

Any dipole starts spinning when moving in the magnetic field. An oceanic ring gathers millions of billions of molecules together. That is why the giant circle movement triggered by the vertical movement of water may last for months and years mechanically. Ions also give more power to the craters. Natrium and Chlorum are charged as well, and their movement in the magnetic field of the Earth also leads to the appearance of the circle movement.

It is not ruled out that the reason for the appearance of the whirlpools off the coast of South America is the same as in other parts of the World Ocean. Scientists are currently studying the influence of those giant funnels on the climate of Latin America and Africa. Such whirlpools show influence on the atmosphere and form cyclonical air mass.[ hurricanes? cyclones?] They can also affect the movement of air mass formed in other places. [ :scared:]For the time being, scientists do not know how the newly discovered water craters can affect the climate of Central and South Americas.

Could this be occurring because of the Gulf Stream changes? (Suriname lies between 1 and 6 degree N latitude.)

This brought to mind a SOTT article from awhile ago, and in more previous articles, I believe, but this article had some of the mechanics of the weakening Gulf Stream:

http://www.sott.net/articles/show/106529-Alarm-over-dramatic-weakening-of-Gulf-Stream-
The current is essentially a huge oceanic conveyor belt that transports heat from equatorial regions towards the Arctic circle. Warm surface water coming up from the tropics gives off heat as it moves north until eventually, it cools so much in northern waters that it sinks and circulates back to the south. There it warms again, rises and heads back north. The constant sinking in the north and rising in the south drives the conveyor.

Global warming weakens the circulation because increased meltwater from Greenland and the Arctic icesheets along with greater river run-off from Russia pour into the northern Atlantic and make it less saline which in turn makes it harder for the cooler water to sink, in effect slowing down the engine that drives the current.

The researchers measured the strength of the current at a latitude of 25 degrees N and found that the volume of cold, deep water returning south had dropped by 30%. At the same time, they measured a 30% increase in the amount of surface water peeling off early from the main northward current, suggesting far less was continuing up to Britain and the rest of Europe. The report appears in the journal Nature today.

Could this be the combined effect of the electrical/magnetic activity increasing in our solar system and its effect on Earth's magnetic field? and may be an effect of what's discussed in Kniall's SOTT article http://www.sott.net/articles/show/220991-Procession-of-the-Damned-Mass-Bird-and-Fish-Deaths-Turning-Up-Everywhere where he discusses magnetic anomalies or RyanX' perspectives about electric relationships between planetary bodies?
(apologies, just saw the time... and need to go, so I don't have time to site his articles)

Sort of reminds me of Calliope's maelstrom in Pirates of the Caribbean; well maybe not that dramatic, but I wonder if anything happens to boats passing through the giant whirlpool.

A very fascinating and somewhat foreboding development.
apologies for the rushed post :-[

I don't know, pravda has a lot of funny articles and they do not give the sources.

Found the following source on this link:

http://www.sciencedaily.com/releases/2011/03/110321162003.htm
which has some additional images (which I haven't mastered in adding to a post)

And this Journal Reference:

1. G. P. Castelão, W. E. Johns. Sea surface structure of North Brazil Current rings derived from shipboard and moored acoustic Doppler current profiler observations. Journal of Geophysical Research, 2011; 116 (C1) DOI: 10.1029/2010JC006575



Sciencedaily.com also listed a NASA source link: http://earthobservatory.nasa.gov/IOTD/view.php?id=6394 which shows a some thermal imaging of deep ocean whirlpools but these are off the coast of Spain and Portugal.

Short on time again this a.m.....later.

"I don't know, pravda has a lot of funny articles and they do not give the sources."

Many things, have changed in Russia since the end of cold war; some good, some bad. Some things will never change. And it is probably still true that there is no truth in 'Pravda'.

A strange spiral appeared near the Black Sea coast.

spiral-black-sea-waters-3-1024x605.jpg


A rare phenomenon has been formed in Abkhazia, on the eastern coast of the Black Sea.

According to local witnesses, the water began to spiral in a giant spiral.

Scientists believe that the whirlpool was most likely formed as a result of collision of water masses with different characteristics (salinity,
temperature, etc.).

It would be interesting to hear any updates about what the scientists find, if they investigate.

This thread has a similar story from 2011, and there was also story in 2018 in the Baltic sea where something similar happened - i'm sure there are more - and in that instance (details below) they were saying it was possibly related to an algae bloom. At least that could explain the contrast of the colour of the water, whether it would explain the spiralling effect, i don't know. I would guess that there's probably been a significant increase in algae as well as how perhaps water is behaving:


"Nutrient-rich, cooler waters tend to promote more growth among marine plants and phytoplankton than is found in tropical waters, the agency added. Phytoplankton and cyanobacteria consume the abundant nutrients in the Baltic-fueled largely by runoff from sewage and agriculture-and reproduce in such vast numbers that their growth and decay deplete the oxygen content of the water."

A research team from Finland and Germany reported this month that oxygen levels in recent years in the Baltic Sea are at their lowest levels in the past 1500 years.

The similar spiral was also spotted in 2015 in the waters of Ibiza between Sa Pedrera (also known as Atlantis) and Es Vedrà.

Several users have shared the strange marine phenomenon on Facebook, wondering what this wonder of nature could be due to.

One of them is Jack Lambert, who on Tuesday was with some friends in the area when, after the storm, he observed the overwhelming spiral, of incredible size, a handful of meters from the coast.

It looks like an eddy to me.
An eddy is a circular current of water.

This NASA image shows a field of eddies in the waters around Tasmania. The swirling motion of eddies in the ocean cause nutrients that are normally found in colder, deeper waters to come to the surface. Here, phytoplankton (tiny ocean plants) feeding on these nutrients color the water beautiful shades of blue and green.

Another nice eddy was spotted this year (8/26/2020) near the Florida Keys.
