Data from: Ocean acidification induces biochemical and morphological changes in the calcification process of large benthic foraminifera
Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed...
