Abstract:
New and compiled Na/Ca measurements of the planktonic foraminifera Globigerinoides ruber. The dataset contains data from foraminiferal samples 1) collected from plankton tows and sediment traps which span a wide salinity range (32.5 - 40.7 salinity units) across the Bay-of-Bengal, Arabian Sea, and Red Sea, 2) cultured in the laboratory under varying carbonate chemistry, and 3) a globally-distributed suite of core-top samples. Na/Ca was measured using both solution and laser ablation ICP-MS. The foraminiferal Na/Ca data are provided alongside environmental parameters for each sample (e.g. temperature, salinity, pH, bottom water Omega calcite), in order to assess the environmental controls on Na/Ca in foraminifera. The data accompany the following manuscript: Gray et al. (2023, doi:10.1016/j.gca.2023.03.011).
