Description:
During February and March 1985, nitrite levels along the northern (approximately 7 degrees to 10 degrees S) Peruvian coast were unusually high. These accumulations occurred in oxygen-deficient waters, suggesting intensified denitrification. In a shallow offshore nitrite maximum, concentrations were as high as 23 micromoles per liter (a record high). Causes for the unusual conditions may include a cold anomaly that followed the 1982-83 El Nino. The removal of combined nitrogen (approximately 3 to 10 trillion grams of nitrogen per year) within zones of new or enhanced denitrification observed between 7 degrees to 16 degrees S suggests a significant increase in oceanic denitrification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Codispoti, L A -- Friederich, G E -- Packard, T T -- Glover, H E -- Kelly, P J -- Spinrad, R W -- Barber, R T -- Elkins, J W -- Ward, B B -- Lipschultz, F -- Lostaunau, N -- New York, N.Y. -- Science. 1986 Sep 12;233(4769):1200-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17756872" target="_blank"〉PubMed〈/a〉
