It is possible that nature gave an opportunity for a partial understanding of the changes and processes

The speed of the current that was tested, the temperature and its salinity allowed the researchers to identify its source and determine its formation as a result of the melting of glaciers in Antarctica, salinity measurements will allow the confirmation of the assumption that the ocean water has been losing its salinity since the 1970s. This is an important figure since water that is less salty (less "dense") does not sink, which causes the flow to slow down.
The current that was tested is one of three that flow from Antarctica towards the equator. The ice water sinks on the eastern shores of the continent and flows north towards the equator, thus creating an oxygen-rich current that forms part of the global circulation of currents, a cycle known as the "ocean conveyor belt" or "overturning circulation" These are current cycles whose importance lies in the vitality they give to the oceans by mixing the water, supplying nutrients and especially supplying oxygen to the water layers below the upper layer.
Excessive importance is attributed to the "conveyor belt" also because the currents affect climatic systems and the absorption of DTP. The rule is that the slower the current it carries less heat and less DTP.
To measure the current, the researchers invested about 30 sensors along the estimated route of the current and checked the data for two years. It turned out that the stream that was tested flows at a depth of about 3-4 km at a speed of about 700 meters per hour, the width of the stream is about 50 km, in quantities that reach up to about 30 million cubic meters per second. (thirty times the Amazon) According to the researchers, no No other current at such a depth is known to move at such a speed and move such large amounts of water
One of the important data shows that the salinity of the water is decreasing, probably as a result of the rapid melting of the Antarctic ice.
It is known that later on the current carries heat from the equatorial region northward, therefore understanding the flow (until now it was considered much slower) will give climatologists another possibility to predict the response of a warming world in which the level of DTP rises, as well as for current weather forecasts.
We all know the northern "continuation" of one of the Antarctic currents, after all, it is the Gulf Stream, thanks to which Europe remains "warmer" than it should have been according to its geographical location. According to the researchers, the movement in the "oceanic conveyor belt" can change, the study of one of the currents will provide the possibility of predicting and understanding how the currents change and what the mutual effect will be: the effect of the changes in the flow on the global climate and the effect of the changes in the climate on the flow.
It is possible that nature gave an opportunity for a partial understanding of the changes and processes, when in mid-February a huge block of ice broke off from the ice tongue that is sent from the continent towards Australia, part of the March Mertz glacier that broke off created an open area where winds blowing from the continent cool water quickly, cold water that sinks and feeds the studied current. There are reports that such an event could affect the entire oceanic conveyor belt and thus cause extreme changes in the weather, but current researchers are not ready to say more than: "It is a natural experiment in nature from which it will be possible to understand the processes we are studying."

Hello
I wanted to ask what is the definition of sea/Oinos? – I drove along the river St. Lawrence in Canada, the GPS device showed that I was at an altitude of 0, the water was salty and full of whales and the place is still called a river, - why not a bay? Where is the border between the river and the sea?
Good to know... something should be done with all this information, and help save nature...
Fewer infections, protecting the environment, everything has an effect here 🙂
Interesting article. Thanks
