- Ethics and applications of isotope analysis in archaeologyPublication . Stantis, Chris; Schaefer, Benjamin J.; Correia, Maria Ana; Alaica, Aleksa K.; Huffer, Damien; Plomp, Esther; Di Giusto, Marina; Chidimuro, Blessing; Rose, Alice K.; Nayak, Ayushi; Kendall, Ellen J.This synthesis explores specific ethical questions that commonly arise in isotopic analysis. For more than four decades, isotope analysis has been employed in archeological studies to explore past human and animal dietary habits, mobility patterns, and the environment in which a human or animal inhabited during life. These analyses require consideration of ethical issues. While theoretical concepts are discussed, we focus on practical aspects: working with descendant communities and other rights holders, choosing methods, creating and sharing data, and working mindfully within academia. These layers of respect and care should surround our science. This paper is relevant for specialists in isotope analysis as well as those incorporating these methods into larger projects. By covering the whole of the research process, from design to output management, we appeal broadly to archaeology and provide actionable solutions that build on the discussions in the general field.
- Strontium isoscapes for provenance, mobility and migration: the way forward.Publication . Spies, Maximilian J.; Alblas, Amanda; Ambrose, Stanley H.; Barakat, Sarah; Barberena, Ramiro; Bataille, Clément; Bowen, Gabriel J.; Britton, Kate; Cawthra, Hayley; Diamond, Roger; Dosseto, Anthony; Evans, Jane A.; Fisher, Erich Christopher; Gray, Kerryn; Heddell-Stevens, Phoebe; Holt, Emily; James, Hannah F.; Janzen, Anneke; Le Corré, Mael; le Roux, Petrus; Lee-Thorp, Julia; Mackay, Alexander; McNeill, Patricia J.; Montgomery, Janet; Mugabe, Bedone; Oelze, Vicky M.; Pfab, Michèle; Richards, Michael P.; Samec, Celeste T.; Santana-Sagredo, Francisca; Serna, Alejandro; Stantis, Chris; Snoeck, Christophe; Stewart, Brian; Stuurman, Cameron; Tarrant, Damon; West, Adam G.; Winter-Schuh, Christine; Sealy, JudithStrontium isotopes (87Sr/86Sr) are increasingly used as a provenance tool in multiple disciplines. Application to biological materials requires knowledge of the variation in bioavailable 87Sr/86Sr across the landscape, potentially in the form of an isoscape (a quantitative model of spatial isotopic variability). This paper summarizes and provides advice on our current understanding of the main concerns in creating and interpreting isoscapes of bioavailable 87Sr/86Sr. Isoscape creation approaches include domain mapping, geostatistical contour mapping and machine learning, the last becoming more readily achievable with the availability of software packages. It is critically important to develop isoscapes at a resolution appropriate for addressing the research questions. Choice of sample materials depends on the research questions and availability: plants or fauna with small ranges are favoured, with some analytes (snails, soil leachates) posing challenges. Interpreting 87Sr/ 86Sr in biological tissues requires considering Sr metabolism and the timing of tissue formation, thus far underappreciated. The numerous sources of error involved in developing and applying isoscapes must be recognized to avoid over-interpreting data and spurious provenance precision. We hope this paper will help researchers investigating provenance, mobility, landscape use and migration to develop the most appropriate isoscapes for their purposes, and possible future use by others.
