This report presents methods, and analytical and quality control procedures for salinity, oxygen, nutrients, total carbon dioxide (TCO2), total alkalinity (TALK), pH, discrete CO2 partial pressure (pCO2), dissolved organic carbon (DOC), chlorofluorocarbons (CFCs), radiocarbon, δ¹³C, and underway carbon measurements performed during the P16S_2005 (6 January–19 February 2005) and P16N_2006 (13 February–30 March, 2006) cruises in the Pacific Ocean. The research vessel (R/V) Roger Revelle departed Papeete, Tahiti, on January 6, 2005 for the Repeat Section P16S, nominally along 150°W, ending in Wellington, New Zealand, on February 19. During this cruise, samples were taken from 36 depths at 111 CTD stations between 16°S and 71°S. The Repeat Section P16N, nominally along 152°W, consisted of two legs. Leg 1 started on February 13, 2006 in Papeete, Tahiti, and finished on March 3, in Honolulu, Hawaii. The R/V Thomas G. Thompson departed Honolulu for Leg 2 on March 10, 2006 and arrived in Kodiak, Alaska, on March 30. During the P16N cruises, samples were taken from 34 or 36 depths at 84 stations between 17°S and 56.28°N. The research conducted on these cruises was part of a series of repeat hydrography sections jointly funded by the National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation (NSF) as part of the Climate Variability Program (CLIVAR)/CO2 Repeat Hydrography Program. The P16S and P16N data sets are available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center (CDIAC). The NDP consists of the oceanographic data files and this printed documentation, which describes the procedures and methods used to obtain the data.
