Abstract:

This data release contains the stable silicon isotope composition of living siliceous Rhizaria collected from the Mediterranean Sea (MS) and the Southern Ocean (SO), and co-located seawater silicon isotopic compositions. Three taxonomic Orders of siliceous Rhizaria (namely Spumellaria, Nassellaria, and Phaeodaria) were measured for their 𝛿30Si, and, whenever possible, provide species-specific information.The samples were collected as part of the RadiCal project funded by the French National Research Agency (18-CEO1-0011-01).
