The ‘Twilight Zone’ Holds Key to Ocean’s Role in Climate Change
The article discussed the role of the twilight zone portion of the ocean in the production of carbon dioxide made by the microorganisms that live in it. There was a foremost global endeavor
that included two research voyages to the Pacific Ocean. Such endeavor exposed surprising information regarding the cycle of carbon dioxide from the time of photosynthesis of marine plants at
the surface of the ocean reached by the sunlight. The research study discovered a vital connection in the procedure that established the capability of the ocean to suck up and amass the carbon dioxide that is building up in the atmosphere. The carbon included in the cells of marine plants eventually descends into the depths of the ocean. These carbons are then accumulated and precluded from coming back to the air as a greenhouse gases. Nevertheless a vast quantity of the carbon that has been taken underneath the surface level through the plummeting substances
of organic material called marine snow are being eaten up by animals and bacteria, and reprocessed in the twilight zone. It is a gloomy portion of the ocean, which is usually one hundred to
one thousand meters underneath the surface.
With the advent use of highly technological tools, the researchers discovered that only twenty percent of the entire carbon in the ocean subsided to the twilight zone in Hawaii whereas fifty percent went to the Northwest Pacific in close proximity to Japan. The article also cited a researcher in the person of Prof. Mary Silver who presented her discovery about the marine snow being the main cause of falling organic material in the ocean and a place of extreme microbial movement. Recently, the researchers had dug up that the twilight zone operate as an entry that permits additional falling materials to go through in several regions while fewer in the other regions. These discoveries set hurdles in the hard work of climate modelers to foretell the function of the ocean in counteracting the effects of greenhouse gases. It is also mentioned that the twilight zone is a vital connection between the surface and the unfathomable ocean.
Further, that in such place the carbons are deposited there and may be able to find its way to return into the atmosphere. The ocean due to lacking storage depth cannot sufficiently stop the elevation of carbon dioxide into the atmosphere. The article also discussed another endeavor that studied the life cycle of the carbon dioxide in marine plants that die and fall or are consumed by the animals and are being transformed into droppings as small feces. It was found out that comparatively, carbons are being transported to the deepness of waters depending on the existing organisms. The fallen substances of marine snow are the ones that provide food to organisms underneath the surface level of ocean, which consists of bacteria that putrefy the substances. As part of the cycle, carbon is transformed into softened organic or inorganic matters that are circulated and utilized again in the twilight zone and can possibly find their passage to the surface and regain its presence in the atmosphere. It was also discovered that in North Pacific, a flora and fauna wherein diatoms, which is a type of microscopic algae control in the surface level, has demonstrated its efficiency in transmitting organic carbon to the twilight zone as compared to the other organisms located in Hawaii. The researchers admitted the fact that they have limited knowledge about the twilight zone and how the organic material decomposes in order to return as carbon dioxide in the air.
These researchers do not just simply give up on such facts instead they collaborated with other groups having the same objective to understand further and better the life in the twilight zone.
