During our two-week visit, we had the opportunity to collaborate with the Photonics for Heritage Science (PhoHS) group as part of the new OtoLIBS project (Otoliths analysis using Laser-Induced Breakdown Spectroscopy).

Using LIBS to evaluate Mg/Ca ratios in limpet shells from Atlantic and sub-Antarctic regions, this study demonstrates that these ratios can serve as robust palaeotemperature proxies when intra-shell variability is carefully accounted for. The results support the expanded use of LIBS for rapid and high-resolution shell-based climate reconstructions in archaeological and environmental research.

We are pleased to share the outcomes of our recent study, “Applying Laser Induced Breakdown Spectroscopy (LIBS) and Elemental Imaging on Marine Shells for Archaeological and Environmental Research,” published in Nature’s Scientific Reports:
