PANTOJA, Silvio. Biogeochemistry of the OMZ of Chile. Gayana (Concepc.) [online]. 2006, vol.70, suppl.1, pp. 62-67. ISSN 0717-6538.  doi: 10.4067/S0717-65382006000300013.

Most microbial reactions are in one way or another associated to decomposition of organic matter, and occurs under two general conditions: in the presence and in the absence of oxygen. Here, we will examine current information on the biogeochemical reactions in the area of the oxygen minimum zone off Chile. The aim of this presentation is to examine mechanisms of processing of organic matter under upwelling and O₂ depletion.
