Abstract

The Southern Ocean exerts a strong impact on marine biogeochemical cycles and global air‐sea CO 2 fluxes. Over the coming century, large increases in surface ocean CO 2 levels, combined with increased upper water column temperatures and stratification, are expected to diminish Southern Ocean CO 2 uptake. These effects could be significantly modulated by concomitant CO 2‐dependent changes in the region's biological carbon pump. Here we show that CO 2 concentrations affect the physiology, growth and species composition of phytoplankton assemblages in the Ross Sea, Antarctica. Field results from in situ sampling and ship‐board incubation experiments demonstrate that inorganic carbon uptake, steady‐state productivity and diatom species composition are sensitive to CO 2 concentrations ranging from 100 to 800 ppm. Elevated CO 2 led to a measurable increase in phytoplankton productivity, promoting the growth of larger chain‐forming diatoms. Our results suggest that CO 2 concentrations can influence biological carbon cycling in the Southern Ocean, thereby creating potential climate feedbacks.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
