We demonstrate that the d13C of shell calcite precipitated in 13C-labeled seawater for 24 h can be resolved and accurately measured using Secondary Ion Mass Spectrometry (SIMS). Specimens maintained at 20 °C were transferred from ambient seawater (d13CDIC = +1.3‰) into seawater with d13CDIC = +51.5‰ and enriched [Ba2+] for 24 h. Specimens were then transferred into ambient seawater with elevated [87Sr] for 6–9 h of calcification, followed by a transfer back into unlabeled ambient seawater until gametogenesis. This technique produced O. universa shells with calcite layers of distinct geochemical signatures. We quantify the spatial positions of trace element labels in the shells using laser ablation ICP-MS depth profiling. Using fragments from the same shells, we quantify intrashell d13Ccalcite using SIMS with a 6 or 8 µm spot (2 SD range ±0.5‰ to 1.7‰). Measured d13Ccalcite values in O. universa shell layers precipitated in ambient seawater are within 2‰ of predicted d13Ccalcite values. In 13C-labeled bands of calcite, 6 µm SIMS spot measurements are within 2‰ of predicted d13Ccalcite values, whereas 8 µm SIMS spots yield intermediate, mixed values. The spatial agreement between trace element and carbon isotope data suggests that 13C and cation tracers are synchronously incorporated into shell calcite. These results demonstrate the ability of SIMS d13C measurements to resolve ~10 µm features in foraminifer shell calcite using a 6 µm spot, and highlight the potential of this technique for addressing questions about ecology, biomineralization, and paleoceanography. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: OCE-0550703, OCE1061676, EAR-0946297, EAR-0319230, EAR-1053466 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Los Alamos National Laboratory # Grant: IGPP:09-RFP-008 #--------------------------------------- # Site Information # Site_Name: Santa Catalina Island # Location: Eastern Pacific Ocean # Country: United States of America # Northernmost_Latitude: 33.26 # Southernmost_Latitude: 33.26 # Easternmost_Longitude: 118.29 # Westernmost_Longitude: 118.29 # Elevation: 0 #--------------------------------------- # Data_Collection # Collection_Name: Catalina d13C Vetter14 # First_Year: # Last_Year: # Time_Unit: # Core_Length: # Notes: Data is from laboratory cultured samples collected in the San Pedro Basin at a depth of 2-5m. #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## SpecimenID identifier,individual foraminifera specimen,,n/a,,Paleoceanography,,,C ## SpotID identifier,individual spot measurements of d18O in specimens,,n/a,,Paleoceanography,,,C ## Dist_mm Distance,,,mm,,Paleoceanography,Distance of the center of a 3 µm spot from the inner shell surface of an individual foraminifer specimen,,N ## Seawater_label label,seawater,,A (ambient) or L (labeled),,Paleoceanography,Identifies whether calcite was precipitated in ambient or labeled seawater, using LA-ICP-MS measurements of intrashell trace element ratios,,C ## d13C_spot d13C of calcite,O. universa,,per mil VPDB,,Paleoceanography,in situ measurements of 3 µm domains within calcite shell,Secondary Ion Mass Spectrometry,N ## d13C_plus2SD d13C of calcite,O. universa,two standard deviation upper bound,per mil VPDB,,Paleoceanography,,Secondary Ion Mass Spectrometry,N ## d13C_minus2SD d13C of calcite,O. universa,two standard deviation lower bound,per mil VPDB,,Paleoceanography,,Secondary Ion Mass Spectrometry,N #------------------------ # Data # Data lines follow (have no #) # Data line format -
