Abstract. The isotope composition of boron (B) in marine biogenic carbonates has been predominantly studied as a proxy 15 for monitoring past changes in seawater pH and carbonate chemistry. In order to derive seawater pH from boron isotope ratio data, a number of assumptions related to chemical kinetics and themodynamic isotope exchange reactions are necessary. Furthermore, the boron isotope composition (

“…Subsequent to the work by Zeebe (2005), significant error was identified for the borate vibrational spectrum term used in Kakihana et al's (1977) theoretical calculation of α (Klochko et al, 2006;Rustad and Bylaska, 2007). An empirical α of 1.0272 (Klochko et al, 2006), using a corrected borate vibrational spectrum term, is now considered to best describe the boron isotope fractionation between dissolved boric acid and borate ion in seawater (Rollion-Bard and Erez, 2010;Xiao et al, 2014). Moreover, due to the ability of some calcifying organisms to alter carbonate chemistry at their site of calcification, paleo-seawater pH cannot always be reliably reconstructed simply by projecting measured δ 11 B of calcium carbonate (δ 11 B CaCO 3 ) onto a theoretical seawater borate δ 11 B (δ 11 B B(OH)…”

Abstract. The boron isotope composition (δ 11 B) of marine biogenic carbonates has been predominantly studied as a proxy for monitoring past changes in seawater pH and carbonate chemistry. However, a number of assumptions regarding chemical kinetics and thermodynamic isotope exchange reactions are required to derive seawater pH from δ 11 B biogenic carbonates. It is also probable that δ 11 B of biogenic carbonate reflects seawater pH at the organism's site of calcification, which may or may not reflect seawater pH. Here, we report the development of methodology for measuring the δ 11 B of biogenic carbonate samples at the multicollector inductively coupled mass spectrometry facility at Ifremer (Plouzané, France) and the evaluation of δ 11 B CaCO 3 in a diverse range of marine calcifying organisms reared for 60 days in isothermal seawater (25 • C) equilibrated with an atmospheric pCO 2 of ca. 409 µatm. Average δ 11 B CaCO 3 composition for all species evaluated in this study range from 16.27 to 35.09 ‰, including, in decreasing order, coralline red alga Neogoniolithion sp. (35.89 ± 3.71 ‰), temperate coral Oculina arbuscula (24.12 ± 0.19 ‰), serpulid worm Hydroides crucigera (19.26 ± 0.16 ‰), tropical urchin Eucidaris tribuloides (18.71 ± 0.26 ‰), temperate urchin Arbacia punctulata (16.28 ± 0.86 ‰), and temperate oyster Crassostrea virginica (16.03 ‰). These results are discussed in the context of each species' proposed mechanism of biocalcification and other factors that could influence skeletal and shell δ 11 B, including calcifying site pH, the proposed direct incorporation of isotopically enriched boric acid (instead of borate) into biogenic calcium carbonate, and differences in shell/skeleton polymorph mineralogy. We conclude that the large inter-species variability in δ 11 B CaCO 3 (ca. 20 ‰) and significant discrepancies between measured δ 11 B CaCO 3 and δ 11 B CaCO 3 expected from established relationships between abiogenic δ 11 B CaCO 3 and seawater pH arise primarily from fundamental differences in calcifying site pH amongst the different species. These results highlight the potential utility of δ 11 B as a proxy of calcifying site pH for a wide range of calcifying taxa and underscore the importance of using species-specific seawater-pH-δ 11 B CaCO 3 calibrations when reconstructing seawater pH from δ 11 B of biogenic carbonates.

Mass Spectrometry Reviews

The present review discusses different mass spectrometric techniques-viz, thermal ionization mass spectrometry (TIMS), inductively coupled plasma mass spectrometry (ICPMS), and secondary ion mass spectrometry (SIMS)-used to determine B/ B isotope ratio, and concentration of boron required for various applications in earth sciences, marine geochemistry, nuclear technology, environmental, and agriculture sciences, etc. The details of the techniques-P-TIMS, which uses Cs BO , N-TIMS, which uses BO , and MC-ICPMS, which uses B ions for bulk analysis or B and B ions for in situ micro-analysis with SIMS-are highlighted. The capabilities, advantages, limitations, and problems in each mass spectrometric technique are summarized. The results of international interlaboratory comparison experiments conducted at different times are summarized. The certified isotopic reference materials available for boron are also listed. Recent developments in laser ablation (LA) ICPMS and QQQ-ICPMS for solids analysis and MS/MS analysis, respectively, are included. The different aspects of sample preparation and analytical chemistry of boron are summarized. Finally, the future requirements of boron isotope ratios for future applications are also given. Presently, MC-ICPMS provides the best precision and accuracy (0.2-0.4‰) on isotope ratio measurements, whereas N-TIMS holds the potential to analyze smallest amount of boron, but has the issue of bias (+2‰ to 4‰) which needs further investigations. © 2016 Wiley Periodicals, Inc.
