Short summary
We present the first large-scale survey of planktonic biogenic carbonate concentrations south of Australia, accompanied by biogenic silica and particulate organic carbon. These suggest that coccolithophores are largely restricted to subantarctic waters and are present in much lower abundance than in Northern Hemisphere polar waters. Comparison to upper ocean properties suggests that thermal tolerance and competition with diatoms for limiting iron may be as influential as ocean acidification.
