Are the simultaneous typhoon and ocean eutrophication the source of organic carbon in wet deposition?

According to the research conducted by some researchers through enclosure experiments, an important means of global marine ecosystem dynamics research, typhoons and eutrophication have a certain impact on the wet deposition of organic carbon, mainly reflected in the nitrogen deposition brought about by these activities.

First of all, let's understand what wet sedimentation is. Simply put, it is the process that various particles or substances in the atmosphere settle to the ground due to the erosion of rainfall and the action of gravity. Nitrogen deposition in the atmosphere has a great influence on the ecosystem of land and water. As the most specific element in the air, nitrogen is widely distributed in nature and plays a very important role in organisms. It is one of the basic elements of amino acid synthesis in organisms, and its importance is self-evident. At the same time, carbon exists widely on the earth, and people are carbon-based creatures. Nitrogen also plays an important role in the flow and transfer of energy. Most researchers believe that nitrogen deposited in land and land waters and coastal waters through atmospheric activities will bring more nitrogen to plants and eventually become carbon through chemical action of plants.

In long-term environmental science experiments and observations, researchers collect daily precipitation endlessly (especially in dry weather, even no precipitation will reduce the estimation of long-term carbon deposition), and then carefully classify these rainfall events according to the rainfall season, the classification of air quality and the magnitude of rainfall, so as to control variables more accurately and achieve a more accurate judgment on the impact of an element.

After studying the wet deposition samples at fixed sampling stations, the researchers found that during the observation period, the nitrogen accumulation caused by typhoon and wet deposition accounted for 1/3 of the total nitrogen accumulation, which was an important source of nitrogen in wet deposition. The accumulation of nitrogen has brought abundant nitrogen fertilizer to plants on land and water, and the transportation of nutrients by typhoons in the sea will also bring more nutrients to land plants. So I think that the simultaneous occurrence of typhoon and marine eutrophication is the source of organic carbon in wet deposition, and it occupies a more important position.
