DOI 10.1007/s10498-010-9111-2 ORIGINAL PAPER Effect of Dissolved Organic Carbon and Alkalinity on the Density of Arctic Ocean Waters
Abstract At constant temperature, the density of deep waters in the oceans is higher than that of surface waters due to the oxidation of plant material that adds NO3, PO4, and Si(OH)4, and the dissolution of CaCO3(s) that adds Ca 2? and HCO3. These increases in the density have been used to estimate...
