Hydrographic and nutrient data from R/V Knorr cruise 73, leg 2 : February to March, 1978 : off the coast of Peru

Abstract

In February and March of 1978 a major cruise was undertaken on the R/V KNORR off the Peruvian coast near 15°S in order to investigate the organic biogeochemical processes associated with upwelling areas. The purpose of this report is to collate the large amount of hydrographic, nutrient, and plankton data generated from various investigators on this cruise and use the report as a standard for the cruise participants. Data for temperature, salinity, oxygen, nitrate, nitrite, ammonium, phosphate, silicate, chlorophyll a, productivity indices, and carbon fixation rates are given.
