Sodium-Calcium Ratios in the Planktic Foraminifera <i>Trilobatus Sacculifer</i> as a Proxy for Sea Surface Salinity
… Na/Ca ratios in the planktic foraminifera <em>Trilobatus sacculifer</em> (<em>T. sacculifer</em> Na/Ca) were measured from a suite of sediment core tops spanning a natural salinity gradient from the North Atlantic subtropical gyre to the South Atlantic subtropical gyre. Initial results from …

Reconstructing Surface Water Carbonate Ion Concentration Changes in the Eastern Equatorial Pacific Across Glacial Transitions
… <em>Globigerinoides ruber</em> and <em>Trilobatus sacculifer</em> to surface water [CO32-] differ in response to changes in seawater [CO<sub>3</sub><sup>2-</sup>]. Therefore, I also measured δ<sup>13</sup>C in these two species as another proxy for surface water …

Climate proxies in planktic foraminifera: Environmental or biomineralisation controls?
… the planktic foraminifera Orbulina universa and Trilobatus sacculifer, cultured under laboratory conditions specifically designed to explore the mechanisms of biomineralisation. These experiments involved either growing specimens in chemically modified seawater, or feeding them with isotopically …
