A new study states the dumping and discarding of iron into the oceans leads to the burial of carbon dioxide in the ocean depths for centuries, diminishing the effect of the climatic changes. The novel study states that fertilization of the seas due to the addition of iron fillings lead to algae blooms. These algae dies and as time pass away, they deteriorate and then submerge into the depth of the deep seas. When these remains sink they tug along the carbon that they have absorbed right down to the ocean floor.
The international experts’ team feels that ocean fertilization by the iron can be given the nod for combating global warming in the universe. The only point of contention is will it harm the marine animals happily swimming in the sea environment. The study emphasizes that when iron is dumped into the deep-sea it eggs on the development of tiny aquatic plants. The aquatic plants transmit heat-trapping carbon to the sea-bed when they perish.
To check this out the science experts cast off approximately seven tonnes of iron sulphate in the Southern Ocean in 2004. Iron sulphide imperative nourishment for aquatic plants.
Nearly half of the heat-trapping carbon that was formed in the process led to the flourishing of a typical alga, called diatoms. The carbon formed submerged to a depth 1,000 meters (3,300 ft) below into the ocean depths along with the algae when they died.
“Iron-fertilized diatom blooms may sequester carbon for timescales of centuries in ocean bottom water and for longer in the sediments,” a collective team of more than a dozen nations mentioned this in the journal Nature.
Carbon lying deep and buried in the depths of the seas can be instrumental in fighting against climatic changes in the atmosphere.The scientists fear that the increase in temperatures leads to droughts, floods, mudslides and rising sea levels and this is primarily due to the augmented carbon-dioxide in the environment.
This research study is the most convincing research that says carbon wrapped up into the algae blooms can submerge deeply and go under the surface to the ocean bed. When the carbon is present in the upper layers of the deep seas it escapes back upwards into the atmosphere. Ocean fertilization “geo-engineering” as it is called, is considered very important to slow down the climatic change.
Nearly a dozen studies have been done earlier that show iron fillings can lead to multiplication of algae but could not give the nod to whether it sank or not.
“I am hoping that these results will show how useful these experiments are,” the lead author of the study, Victor Smetacek of the Alfred Wegener Institute in Germany was heard claiming.
But experiment needs to be carried out on a large scale, on ocean fertilization and sea dumping, are at the moment forbidden by the International London Convention due to the suspected side effects.
