Changes in the degree of nutrient consumption in Antarctic Zone (AZ) of the Southern Ocean may have played a major role in controlling past carbon dioxide levels and therefore past climate. The \(^{15}\)N / \(^{14}\)N ratio (\(\delta\)\(^{15}\)N) of diatom-bound organic matter (DB \(\delta\)\(^{15}\...
