Effect of CO2 enrichment on phytoplankton photosynthesis in the North Atlantic sub-tropical gyre
he effects of changes in CO2 concentration in seawater on phytoplankton community structure and photosynthesis were studied in the North Atlantic sub-tropical gyre. Three shipboard incubations were conducted for 48 h at similar to 760 ppm CO2 and control (360 ppm CO2) from 49 degrees N to 7 degrees...
