The density measurements were obtained at 1 atm by using a magnetic float densitometer. The six isotopic standard waters used included distilled Mediterranean deep water, distilled Yellowstone National Park water, and ion exchanged Miami tap water. Dissolved gases were found to decrease the density by 3. 0 plus or minus 0. 2 multiplied by 10** minus **6g cm** minus 3 at 4 degree C. The apparent molal volumes of air were found to be nearly independent of saturation concentration and temperatures between 0 degree and 30 degree C. The decrease in density (to plus or minus 0. 2 multiplied by 10** minus **6) can be determined from, DELTA d equals minus 2. 6 multiplied by 10** minus **3 multiplied by c where c is the total concentration of air in moles/liter (O//2, N//2, Ar and CO//2) over the saturation and temperature range of ocean waters. The dissolved air experimental results were found to be in good agreement with those determined from partial molal volume data for gases determined by other workers.
