MIT's study that the ocean will be discolored due to climate change



Due to climate change, Many parts of the ocean will change color at the end of the century.

According to a study by the Massachusetts Institute of Technology (MIT) Marine phytoplankton, A microscopic bird in charge of the green part of the water, Life cycle, configuration, and deployment.Due to climate change

These organisms They synthesize solar energy using chlorophyll. Thus, the green part of the water is synthesized.

In an article posted on Natural communication, The researcher We have developed a model that simulates the growth and interaction of other phytoplankton species, And how the mix of species at different places will change as global temperatures rise.

With global warming, the sea is bluish or blue, but new tones continue. The color change indicates the change chain of marine life.

Scientists, By 2100, more than 50% of the world's oceans will be discolored due to this climatic phenomenon. These changes will be very subtle and will not be visible to the human eye, but will be possible with optical sensors.

"Changes caused by heating are less nutrients that reach the surface layer.Therefore, phytoplankton is most likely to decline in much of the ocean. "Said MIT researcher Stephanie Dutkiewicz, lead author of the Jai study.

According to the researcher, Temperature also affects the growth rate of phytoplankton. He explained that species adapted to hot water will grow much faster than species adapted to cold water, so there will be regional changes in the composition, quantity and distribution of marine microorganisms filling the water.

"The sea will remain blue. Some parts of the northern and southern parts of the equator and subtropical areas are more blue. Green will be more present in tropical coastal waters where polar regions and phytoplankton absorb heat better.

Scientists also In order to better match the color of the ocean in the future, you must include other microscope components. Mineral and sea water such as sea salt.

Sea plants need nutrients such as nitrogen or phosphorus in addition to the sun.When global warming slows the ocean circulation, these nutrients do not reach the surface.
