Impacts of elevated CO2 on organic carbon dynamics in nutrient depleted Okhotsk Sea surface waters

International Atomic Energy Agency (IAEA) Publications

Increasing CO2 in seawater (i.e. ocean acidification) may have various and potentially adverse effects on phytoplankton dynamics and hence the organic carbon dynamics. We conducted a CO2...
