m115.dat (File 5)

This file provides hydrographic, carbon dioxide, and chemical data for the 78 stations occupied during the R/V Meteor Cruise 11/5. Each line consists of a station number, cast number, sample number, bottle number, CTD pressure, CTD temperature, CTD salinity, potential temperature, bottle salinity; concentrations of oxygen, silicate, nitrate, nitrite, phosphate, and total carbon; pCO₂; pCO₂ temperature; potential density; and data quality flags. The file is sorted by station number and pressure and can be read by using the following FORTRAN 77 code [contained in m115dat.for (File 3)]:
