“…shells a variety of correlations between elemental ratios and SST were found 19–22 , with no consistent explanation for any of the variabilities or anomalies that were encountered. Generally, it is argued that variations in study location as well as vital or physiological effects working between and within individual mollusc specimens prevent a comprehensive and unambiguous interpretation of their elemental records 11,21–28 .…”

Elemental analysis of biogeochemical archives is an established technique used to study climate in a range of applications, including ocean circulation, glacial/interglacial climates, and anthropogenic climate change. Data from mollusc archives are especially important because of their global abundance and sub-annual resolution. Despite this potential, they are underrepresented among palaeoclimate studies, due to enigmatic physiological influences skewing the elemental record. Understanding the patterns behind these influences will improve data interpretation and lead to the development of new climate proxies. Here, we show for the first time that extensive spatial mapping of multiple mollusc specimens using Laser Induced Breakdown Spectroscopy (LIBS) across a wider region can resolve enigmatic patterns within the elemental record caused by physiological influences. 2D elemental (Mg/Ca) maps of whole limpet shells (Patella caerulea) from across the Mediterranean revealed patterns of variability within individual mollusc records as well as within isochronous parts of specimens. By registering and quantifying these patterns, we established previously uninterpretable correlations with temperature (R 2 > 0.8, p < 0.01). This outcome redefines the possibilities of accessing sub-annual climate proxies and presents the means to assess annual temperature ranges using oxygen isotope analysis requiring only 2 samples per shell.

“…To avoid matrix‐dependent calibration effects for all LA‐ICP‐MS instruments, carbonate RMs would therefore be preferable. So far, only pressed powder pellets from synthetic or natural calcium carbonate RMs are available, such as MACS‐1 or MACS‐3 from the USGS (e.g., Mertz‐Kraus et al , Jochum et al , Wassenburg et al , Marali et al ). The ablation of such pellets is not as reproducible as for glass samples, because the powders of the RMs are mostly coarse‐grained with grain sizes of about 10–15 µm.…”

Homogeneity, mass fractions of about forty trace elements and Sr isotope composition of Ca carbonate reference materials (RMs) between original and nano‐powdered pellets are compared. Our results using nanosecond and femtosecond LA‐(MC)‐ICP‐MS show that the nano‐pellets of the RMs MACS‐3NP, JCp‐1NP and JCt‐1NP are about a factor of 2–3 more homogeneous than the original samples MACS‐3, JCp‐1 and JCt‐1, and are therefore much more suitable for microanalytical purposes. With the exception of Si, the mass fractions of the synthetic RM MACS‐3 agree with its fine‐grained analogue MACS‐3NP. Very small, but significant, differences between original and nano‐pellets are observed in the RMs JCp‐1 and JCt‐1 for some trace elements with very low contents, indicating the need for re‐certification. Strontium mass fractions in the analysed RMs are high (1500–7000 mg kg−1), and their isotope compositions determined by LA‐MC‐ICP‐MS in the original and the nano‐pellets agree within uncertainty limits.

“…In many organisms, Sr/Ca and Mg/Ca ratios serve as useful paleo-temperature proxies (e.g., foraminifera, Nürnberg et al, 1996;corals, Goodkin et al, 2007;sclerosponges, Rosenheim et al, 2004;bivalves, Zhao et al, 2017b). As shown by several studies, in the bivalve A. islandica vital effects have an important effect on the incorporation of these two trace elements into the shell (Toland et al, 2000;Foster et al, 2008Foster et al, , 2009Schöne et al, 2011Schöne et al, , 2013Marali et al, 2017a;Wanamaker and Gillikin, 2018). Most of these studies, which are based on small samples sizes (3-8 specimens vs. 73 this study), concluded that it is unclear whether these metal-tocalcium ratios in the shells of A. islandica can be used as temperature proxies.…”

“…Levels of strontium (Sr) and magnesium (Mg) in bivalve shells have been proposed as proxies for water temperature (Klein et al, 1996;Schöne et al, 2013). However, Sr/Ca and Mg/Ca ratios are still difficult to interpret because the incorporation of trace and minor impurities in the shell carbonate is partly physiologically controlled (e.g., Urey et al, 1951;Purton et al, 1999;Lorrain et al, 2005;Freitas et al, 2005Freitas et al, , 2006Schöne et al, 2010Schöne et al, , 2013Marali et al, 2017a;Geeza et al, 2018). Published results on the relationship between the Sr/Ca and Mg/Ca ratios of bivalve shells and temperature are highly ambiguous; previous studies have reported a positive relationship (Stecher et al, 1996;Hart and Blusztajn, 1998;Toland et al, 2000), negative relationship (Dodd, 1965;Stecher et al, 1996;Surge and Walker, 2006;Schöne et al, 2011), and no relationship (Gillikin et al, 2005;Strasser et al, 2008;Izumida et al, 2011;Wanamaker and Gillikin, 2018).…”

Long-term and high-resolution environmental proxy data are crucial to contextualize current climate change. The extremely long-lived bivalve, Arctica islandica, is one of the most widely used paleoclimate archives of the northern Atlantic because of its fine temporal resolution. However, the interpretation of environmental histories from microstructures and elemental impurities of A. islandica shells is still a challenge. Vital effects (metabolic rate, ontogenetic age, and growth rate) can modify the way in which physiochemical changes of the ambient environment are recorded by the shells. To quantify the degree to which microstructural properties and element incorporation into A. islandica shells is vitally or/and environmentally affected, A. islandica specimens were reared for three months under different water temperatures (3, 8 and 13 °C) and food concentrations (low, medium and high). Concentrations of Mg, Sr, Na, and Ba were measured in the newly formed shell portions by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). The microstructures of the shells were analyzed by Scanning Electron Microscopy (SEM). Shell growth and condition index of each specimen were calculated at the end of the experimental period. Findings indicate that no significant variation in the morphometric characteristics of the microstructures were formed at different water temperatures or different food concentrations. Shell carbonate that formed at lowest food concentration usually incorporated the highest amounts of Mg, Sr and Ba relative to Ca (except for Na) and was consistent with the slowest shell growth and lowest condition index at the end of the experiment. These results seem to indicate that, under food limitation, the ability of A. islandica to discriminate element impurities during shell formation decreases. Moreover, all trace element-to‑calcium ratios were significantly affected by shell growth rate. Therefore, physiological processes seem to dominate the control on element incorporation into A. islandica shells.
