The reasons why the ocean loses its scourge

  Whole Ocean

In the largest ocean area where the rate of oxygen is so weak that it cannot be measured, the whip escapes atmosphere. Located in the South Pacific, this region contributes largely to the scourge loss of the global ocean mass. In a study published in Nature, some Scientists they specify the main mechanisms that are in play.

The human disturbance of the cycle of nitrogen is particularly important. Anthropic flows, related to industry and Fertilizers chemical, are as important as natural flows. Industrial activities emit 90 million tons of oxide from nitrogen (Nox) and ammonia (NH3) per year to the atmosphere. Chemical fertilizers diffuse 80 million tons of chemical compounds nitrogen on earth per year.

Understand the cycle of nitrogen is a key factor in predicting the response of the ocean in the cultural, climate, since it is one of the life-limiting nutrients in oceans. The scourge exchanges are dominated by microbial transformations, the biomass being able to assimilate it only in the form of minerals (NO3- and NH4 +).

In the ocean there are areas with a minimum of oxygen (OMZ) where microbes are able to use various sources of nitrogen dissolved. They produce greenhouse gases such as oxide nitric, or azote protoxide (N2O), 300 times more powerful than CO2, which is then released into the atmosphere.
