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 Niño. 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° to 16°S suggests a significant increase in oceanic denitrification.||URI:||http://hdl.handle.net/10553/50878||ISSN:||0036-8075||DOI:||10.1126/science.233.4769.1200||Source:||Science [ISSN 0036-8075], v. 233, p. 1200-1202|
