The bulk ice pCO2 ranged from 60 to 330ppmv indicating that sea ice at temperatures above −4 C is undersaturated com- pared to the atmosphere (390 ppmv). This study adds to the few existing studies of CH4 and CO2 in sea ice, and we con- clude that subarctic seawater can be a sink for atmospheric CO2, while being a net source of CH4.

Increasing anthropogenic carbon dioxide is causing changes to ocean chemistry, which will continue in a predictable manner. Dissolution of additional atmospheric carbon dioxide leads to increased concentrations of dissolved carbon dioxide and bicarbonate and decreased pH in ocean water. The concomit …

människor sedan dess höjt lufthavets koldioxidhalt så att den nu är 390 ppmv. Med nuvarande utsläpp fortsätter halten att stiga med åtminstone 2 ppmv per år. Current atmospheric pCO 2 (~390 ppmv) is unprecedented since at least 3 million years ago (Ma), and levels projected for the next century were last seen more Atmospheric co2 concentration effects on rice water use and biomass production For 390 ppmv [CO2], Kc was about 1 during crop establishment but increased 390 - 440 kg/m3.

2 at 390 ppmv. Doubling of the P CO2 from 390 ppmv to 780 ppmv yields the following; [H+] = 8.65 x 10-9 M (i.e., pH = 8.06) and [Ca2+] = 6.78 x 10-4 M In other words, the solubility of CaCO 3 increases by 25% if P CO2 doubles. Note: For gases, a ppm is defined as a volume ratio (hence ppmv) and since the partial

This study adds to the few existing studies of CH4 and CO2 in sea ice, and we con- clude that subarctic seawater can be a sink for atmospheric CO2, while being a net source of CH4. John Marshall @52, if you run your car in a closed garage and measure the CO2 concentration in the garage, it will be well above 390 ppmv. It would be obviously foolish to conclude from that that global CO2 concentrations are greater than 390 ppmv.
