New Arctic Nitric Resources – ScienceDaily



Scientists have shown that their alga and algae bacteria have a " make the essential element of nitrogen available in the Arctic Ocean. The microbial process of "nitric configuration" converts the element into a form that can use organisms, and has recently been found in the frosty polar waters. This shift may be due to climate change and may affect global chemical tours, according to the study published in the # 39; National Academy of Sciences EventsSouth Westerly

Without a nitric resource, san Artaig mytoplankton was constantly constrained in the amount of carbon that they can extract from their harbor and high air. The new nitric source of UCYN-A may offer more productive methoplanctans, which reduce carbon levels in the atmosphere.

"It was very awesome to find this process in the Arctic," said Deborah Bronk, one of the authors and leader and director of Bigelow Laboratory for Ocean Sciences. "We thought there was no nitrogen resolution but in tropical and sub-tropical waters. This result may have a profound effect on acute and tangible chemical tours."

Just like the use of garden flowers and other ground plants nitrig grows, the element is also essential for microscopic pond plants known as phytoplankton. However, most of the nitrics in the ocean are in a gas format that can not; Most of organisms, including people, can be used. Only a few types of microscopes are capable of taking the job. Scientists have long believed that the main phytoplankton was not the case; nitric situation in the ocean; lived in warm waters but, and it was essential that there was nitric arrangement in the Arctic Ocean.

In 2017, Bronk published and paper co-workers showed that a nitric situation was in place; happened in Arctic Ocean, but they still did not know which organisms were responsible for the process. They were surprised to find out that UCYN-A is a singilte-cella cyanobacteria that is; live in simbiosis with algae and which will flourish in warm water.

"One of the things that this study has shown is that the ideas we propose to stop us from finding unexpected things," said Bronk. "More we learn about the ocean, the more we can see that organisms are extremely productive in what they can do and where they can live."

How to spend the Arctic Ocean and its sea ice melting, the season grows for phytoplankton to grow longer. The research team believes that while UCYN-A has been in the Arctic for a while, the warmer powers that have come from climate change have been encouraged to start on & # 39; nitric situation. They also believe that this move in the UCYN-A activity could, therefore, affect global climate. As mytoplankton grows, they will grow. remove carbon from the ocean and at the end of the atmosphere – but they need nitrics to do this, which can provide more UCYN-A.

The researchers have estimated that Arctic UCYN-A is currently in & # 39; counted for around two hundred percent of global nitrogen arrangement. Continue to & # 39; explore this process and its & # 39; incorporating it into global biology models, it will develop an expression of climate and understanding of important oceanic walks. Researchers believe that this increase in Arctic nitrogen may be able to; affecting biogeochemical walks in North America, causing more travel in sea tours.

"Due to previous research, we were able to identify that this process is new," said Bronk. "This study shows that we are sometimes very important that we do not find a process you are looking for. We need to store and give data to people so that we can learn how to change the ocean. "
