Concentration of total organic carbon in waters of the Atlantic Ocean

In pursuance of previous studies water samples were taken in the Atlantic and Mediterranean during the 12th, 14th and 15th cruises of RV Mikhail Lomonosov in 1962-1964 to determine total and particulate organic carbon and permanganate oxidizability. Preliminary processing of the water samples was ca...

Description
Summary:In pursuance of previous studies water samples were taken in the Atlantic and Mediterranean during the 12th, 14th and 15th cruises of RV Mikhail Lomonosov in 1962-1964 to determine total and particulate organic carbon and permanganate oxidizability. Preliminary processing of the water samples was carried out in the normal manner in the on-board laboratory immediately after they had been taken: destruction of bicarbonates and carbonates by precise addition of acid (by alkalinity) and evaporation to dryness at 50-60°C. It is quite probable that the corresponding volatile fraction of organic matter is lost under these conditions. In discussion it was demonstrated that it may now be assumed that the carbon of the volatile fraction averages approximately 15% of total carbon, i.e., 15% of the sum of organic carbon of the volatile and nonvolatile fractions. Oxidizability was determined in all samples in the on-board laboratory.
