8.5 p16ap17a.dat (File 7), p17ep19s.dat (File 8), and p19c.dat (File 9)

These files provide hydrographic, carbon dioxide, and chemical data for the all stations occupied during the R/V Knorr expeditions along WOCE Sections P16A/P17A, P17E/P19S, and P19C. Each record contains a station number, cast number, sample number, bottle number, CTD pressure, CTD temperature, CTD salinity, CTD oxygen, potential temperature, bottle salinity, oxygen, silicate, nitrate, nitrite, phosphate, CFC-11, CFC-12, TCO₂, pCO₂, pCO₂ temperature, and data-quality flags. The files are sorted by station number and pressure and can be read by using the following FORTRAN 77 code [contained in data.for (File 3)]:
