Abstract

Studies of the nitrite-nitrogen distribution off the western coast of South America have shown significant concentrations in surface waters (up to 0.5 µg-at/l) and a widespread primary maximum near the top of the thermocline. Below the surface layer, where the oxygen minimum contains less than 0.2 ml/l of dissolved oxygen, a secondary maximum was present south of 10°S, within 1000 km of the coast....
