在1985年2月和3月，沿着北方（约7.degree.）的亚硝酸盐水平。到10 ° S）的秘鲁海岸线异常高。这些积累发生在缺氧的沃茨，这表明加强反硝化作用。在浅海的亚硝酸盐最大值中，浓度高达每升23微摩尔（创历史新高）。异常情况的原因可能包括1982-83年厄尔尼诺之后的寒冷异常。尼诺在7.degree.之间观察到的新的或增强的去硝化区域内的结合氮（每年约3至10万亿克氮）的去除。到16 ° S表明海洋反硝化作用显著增加。
During February and March 1985, nitrite levels along the northern (approximately 7.degree. to 10.degree.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 dentrification observed between 7.degree. to 16.degree.S suggests a significant increase in oceanic denitrification.
