This report completes the compilation of data collected on STEP-I Expedition of the Scripps Institution of Oceanography and the Inter-American Tropical Tuna Commission from 15 September to 14 December, 1960, to the Peru Current and offshore waters of Peru and northern Chile. Part I (SIO Ref. 61-9) included the physical and most of the chemical data; this report, Part II contains the biological, the photometric and some additional chemical data. The purposes of the expedition, the list of scientific personnel and the procedures for the collection of hydrographic data were given in Part I. Station numbers here correspond to those in Part I. Nitrate data are given in the appendix; determinations were made ashore after the end of the cruise, so the data were not included in Part I in order not to delay the distribution of the physical and other chemical data whose determinations were made during the cruise.
