Depletion of oxygen due to it caused dead zones as in the Gulf of Mexico.
Treating soybeans with apatite nanoparticles has shown to be a possible way of decreasing this phenomenon due to decreased mobility and solubility. Abundance of iron was shown by Menzel and Ryther to be the primary limiting factor of this process in the Sargasso Sea. Depletion of oxygen due to it caused dead zones as in the Gulf of Mexico. This process leads to diatoms and green algae being dominated by cyanobacteria, and it causes the overall amount of (*) phytoplankton to increase. David Schindler's research on this phenomenon led to the use of phosphate-free detergents. Fertilization accelerates this phenomenon, which causes algal blooms such as Lake Erie's Cladophora outbreak. For 10 points, name this phenomenon in which nitrogen and phosphorus lead to contamination of drinking water and death of marine fauna through the "overnourishment" of lakes or other bodies of water.
