Sulfur speciation in bottom sediments from the area of the Peru upwelling has been studied. Data on sulfur contents in different compounds (sulfide, elemental, sulfate, pyritic and organic), water content, Eh, and organic carbon content in the bottom sediments have been obtained. The bottom sediments from the area are characterized by high content of organic carbon and low contents of total and reactive iron; this is typical for bottom sediments from ocean upwelling areas. Intense process of sulfate reduction occurs in the bottom sediments of the area, and accumulation of reduced sulfur compounds derivated from bacterial hydrogen sulfide does not exceed previously known values for other regions of the ocean.
