This file provides hydrographic, carbon dioxide, and chemical data for the 111 stations occupied during R/V Meteor Cruise 15/3. Each line consists of a station number; cast number; sample number; bottle number; CTD pressure, temperature, salinity, and oxygen; potential temperature; bottle salinity; concentrations of oxygen, silicate, nitrate, nitrite, phosphate, total carbon dioxide, and total alkalinity; pCO2; pCO2 temperature; CFC-113; CCl4; CFC-12; CFC-11; 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 m153dat.for (File 3)]:
