Many scientists say that we know more about outer space than the depths of our oceans.
-
While we've given our planet's oceans separate names, in reality, there's no border between them, and currents continually flow between them and mix their waters.
-
The Atlantic and Pacific Oceans are the two largest seas on the planet, covering half of the Earth's surface, meet at the southernmost tip of South America called Cape Horn.
-
According to topographers, the line that marks the border between the Atlantic and the Pacific Ocean runs straight between Cape Horn and Antarctica.
-
In this region, a strong current carries water from west to east, sweeping water from the Pacific into the Atlantic.
-
On the other side of the planet, the Gulf of Alaska, an arm of the Pacific Ocean holds a spectacular view which seems to be the confluence of two oceans, whereas it is actually the glacial meltwater meeting the offshore waters.
-
The color variations found here draw a clear line between these two oceans.
-
The heavier clay materials with iron and sediments at that harbor at the Gulf make the waters at Gulf appear darker than the glacial meltwaters.
-
The reason for this strange phenomenon is due to the differences in water density, the salinity, and temperatures of both these oceans keep their waters demarked and separated.
-
This phenomenon is called water stratification.
-
The nutrients present don't mix, and the photosynthesis process for the plankton present in oceans is limited.
-
Hence the concentration of planktons present also differs, which in turn absorbs light and scatter in different directions.
-
The mixing boundary is, of course, a curve but on the surface, it seems like a zigzag line, or like a boundary.
-
But it isn't only the truth, what you see is the extreme level of mixing of waters.
-
It may change with time and temperature, but due to the large volume of both the waters, change is negligible and have a fixed zone.
-
It seems amazing, and like a miracle.
-
Yes, it is a miracle, miracle of science and nature.
