Concentrations of total organic carbon on vertical profiles in waters of the North Atlantic in January 1994

Not filtered water samples were taken in 10 ml ampoules (sealed immediately after being acidified with phosphoric acid to pH<2, sampling), or 40 ml screw-lid vials, and measured onboard at sampling or next days, or frozen (-20°C) until being acidified and measured in home labs.Carbon measurement...
