Effects of ocean acidification on the physiological performance and carbon production of the Antarctic sea ice diatom Nitzschia sp ICE-H
Ocean acidification (OA) resulting from increasing atmospheric CO2 strongly influences marine ecosystems, particularly in the polar ocean due to greater CO2 solubility. Here, we grew the Antarctic sea ice diatom Nitzschia sp. ICE-H in a semicontinuous culture under low (similar to 400 ppm) and high...
