Recent news uncovered that the ocean’s physical and biogeochemical conditions are rapidly changing over time. The changes observed include “continuing trends of surface warming, increase in salinity, loss of dissolved oxygen (DO), increase in carbon dioxide (CO₂), and ocean acidification (OA) effects.” 

A study by Olof Linden, World Maritime University, Malmö, Sweden attributed the root cause of such a decline of Oxygen level and increase of Carbon Dioxide level to man made global warming

No other chemical parameter is of such importance to all higher marine life as dissolved oxygen. From available data it is obvious that oxygen-limited areas have expanded throughout most of the Atlantic during the last 50 to 100 years and are clearly related to human activities.

Oxygen limited waters, hypoxic and even anoxic conditions are now found in many coastal areas in the Atlantic Ocean including in connected seas like the Mediterranean, the Black Sea, the North Sea and the Baltic Sea, and the Gulf of Mexico.

Sediment studies show that anoxic conditions have been present in deep waters in the past, long before
anthropogenic activities started to have an influence on the marine environment. However, the present observed deoxygenation in coastal and offshore areas is clearly linked to human activities such as input of nutrients and organic matter, and increasing temperatures as a result of climate change.

The expanding oxygen minimum zones affect the entire Atlantic ocean ecosystem, its biodiversity and
productivity.

In addition to many coastal waters, oxygen limited waters are also found at mid-water depths (typically 300-1000 m) in the Atlantic Ocean basins, particularly the Equatorial and South Atlantic. The oxygen concentrations in these areas have decreased during the last 60 years, partly due to ocean warming, and partly as a result of decreased mixing and ventilation.

Continued spreading of deoxygenated areas in the Atlantic, as well as the rest of the world ocean, must be considered a most serious environmental problem with enormous potential impacts on biodiversity and human societies.

However, as I manifested it earlier, that the continuous movement of the 2 magnetic poles to the East that started in 1850s and has picked up speed in the last 2 decades, has resulted in the weakness of the magnetic field mid distance between the 2 magnetic poles, across the Atlantic Ocean, in what is termed South Atlantic Anomaly. The weakness of the magnetic field over that part of the world allowed charged particles emitted by the Sun mainly Protons, to penetrate the Atmosphere layers including the Troposhpere to continuously bomard the Ocean at high keinetic energy leading to ocean warming.

The warming of the ocean frees the Methane (CH₄) out of the Methane Hydrates which lies mostly at shallow waters between 0 and 500 meters (800 feet) below sea level, which in turn unit with Oxygen (O₂), whether dissolved in water or in the air to produce one (CO₂) and two (H₂O) per Methane molecule. While some of the Methane molecules join with dissolved O₂, others would burst out of the water into the air, where they unit with O₂, resulting in the generation of 3 green house gas’ molecules; one Carbon Dioxide and two Water vapour, adding to global warming and reduction of Oxygen level in the atmosphere as well .

I presented another evidence over of nature made warming, where the climate above 1.2 million kilometers approximately in the midst of the Indian ocean, far from any land or civilization, is experiecing a serious warming. The consequence of the weakening of the magnetic field over the Atlantic Anomaly has reached that far east, as stream of warm ocean freed the store Methane Hydrates and resulted in forming a zone in the air full of CO₂ and H₂O.
