Paired X-ray Micro CT Scanning and individual foraminifera isotopic analysis reveal (de)coupled changes in carbonate preservation and temperature
<p>To assess the coupling between drivers of isotopic variability and carbonate dissolution in foraminifera, we combine individual foraminiferal carbon and oxygen isotopic analyses (IFA) and X-ray MicroCT Scanning (XMCT)-based measurements of test densities (a proxy for the extent of post-depositional dissolution). As a proof-of-concept application of this approach, we analyze Globigerina bulloides tests from both coretop and downcore (latest Miocene/earliest Pliocene-aged) sediment from Ocean Drilling Project (ODP) Site 1088 (Agulhas Ridge).<br>Sediments from both the core intervals were wet-sieved over a 150 μm sieve and oven-dried at 55°C overnight. Individual tests of G. bulloides were picked from the >150 μm size fraction and gently brushed with the wet tip of a paintbrush to remove any adhering clay. Broken or partially fragmented tests were avoided. 25-50 individuals were mounted on a 1.2cm x 1 cm cardboard sample holder using double-sided carbon and imaged at a time on a Bruker Skyscan 1272 Micro-CT Scanner. In total, 123 individuals from the coretop sample and 88 individuals from the downcore sample were scanned.<br>Stable carbon (δ¹³C) and oxygen (δ¹⁸O) isotopic compositions of individual foraminifera were measured using a Kiel Carbonate Device IV coupled to a Thermo Fisher MAT 253 Plus Isotope Ratio Mass Spectrometer (IRMS). All individuals were weighed on a Sartorius ultramicrobalance before analysis, and only samples with mass >10 µg were analyzed as per the long-term precision setup of analyzing small quantities of carbonates on this machine. The XMCT-IFA dataset in this study consists of δ¹³C and δ¹⁸O values of 90 foraminifera (67 coretop and 23 downcore individuals). We compare population averages of XMCT parameters and isotopic compositions from both the coretop and downcore sediments.</p>
