Free Ocean CO 2 Enrichment of the Antarctic Sea Floor: ANTFOCE

Polar communities are expected to experience the impacts of ocean acidification sooner and more heavily than other regions, and serve as indicators of the consequences we can expect from increasing ocean CO2 concentrations. Few studies to date have focused on impacts of acidification on in situ bent...
