This record presents the strontium (Sr) data used in the paper 'The Role of Acantharia in Southern Ocean Strontium Cycling and Carbon Export: Insights from Dissolved Strontium Concentrations and Seasonal Flux Patterns', Sun et al. (2024). All methods for the dataset are thoroughly documented and cross-referenced in the paper. Introduction: The dataset examines how Acantharia, marine protists with celestite (SrSO4) skeletons, influence strontium (Sr) and carbon cycling in the Southern Ocean. Acantharia utilize surface Sr to build skeletons and release it upon death, significantly impacting Sr distribution. Their cysts, also celestite-based, act as effective ballast for particulate organic carbon (POC). Analysis of dissolved and particulate Sr concentrations indicates Acantharia's dominant role in Sr cycles, with seasonal flux variations, particularly intense in January/February, likely linked to increased productivity and ocean temperatures during that period. Sampling Sites: Dissolved and particulate Sr ...
