“…Therefore, oxygen isotope signatures recorded in ancient shells can be potentially used for reconstruction of past seawater temperatures, but also for determination of subsistence strategies and settlement patterns of past populations through the study of season of shell collection (Burchell et al, 2013;Colonese et al, 2009;Culleton et al, 2009;Mannino et al, 2003).…”

“…Due to their annual resolution, analysis of the internal growth patterns in different bivalve species have been used successfully to identify multiyear and decadal oscillation patterns such as the North Atlantic Oscillation (NAO); [ Brocas et al ., ], Arctic Climate Regime Index (ACRI) [ Carroll et al ., ], or El Niño Southern Oscillation (ENSO) [ Schöne et al ., ]. Bivalve sclerochronology has additionally been used to identify multidecadal climate trends [ Brey et al ., ], subannual environmental patterns (L. Beierlein et al, The seasonal water temperature cycle in the Arctic Dicksonfjord (Svalbard) during the Holocene Climate Optimum derived from Arctica islandica shells, submitted to The Holocene , 2014] and has successfully been applied in archaeological studies, where, for example, bivalve shells from shell middens (mounds of discarded shell materials at prehistoric settlements) are used to identify seasonal patterns of resource procurement [ Burchell et al ., ; Hallmann et al ., ].…”

Biological hard parts and skeletons of aquatic organisms often archive information of past environmental conditions. Deciphering such information forms an essential contribution to our understanding of past climate conditions and thus our ability to mitigate the climatic, ecological, and social impacts of a rapidly changing environment. Several established techniques enable the visualization and reliable use of the information stored in anatomical features of such biogenic archives, i.e., its growth patterns. Here, we test whether confocal Raman microscopy (CRM) is a suitable method to reliably identify growth patterns in the commonly used archive Arctica islandica and the extinct species Pygocardia rustica (both Bivalvia). A modern A. islandica specimen from Norway has been investigated to verify the general feasibility of CRM, resulting in highly correlated standardized growth indices (r > 0.96; p < 0.0001) between CRM-derived measurements and measurements derived from the established methods of fluorescence microscopy and Mutvei's solution staining. This demonstrates the general suitability of CRM as a method for growth pattern evaluation and cross-dating applications. Moreover, CRM may be of particular interest for paleoenvironmental reconstructions, as it yielded superior results in the analysis of fossil shell specimens (A. islandica and P. rustica) compared to both Mutvei staining and fluorescence microscopy. CRM is a reliable and valuable tool to visualize internal growth patterns in both modern and fossil calcium carbonate shells that notably also facilitates the assessment of possible diagenetic alteration prior to geochemical analysis without geochemically compromising the sample. We strongly recommend the CRM approach for the visualization of growth patterns in fossil biogenic archives, where conventional methods fail to produce useful results.

“…In response to seasonal changes, hunter-gatherers can practice resource management, including season-specific bivalve harvesting (Smith and Wishnie 2000) and drying and storage of their meat (Henshilwood et al 1994). Using stable oxygen isotope analysis of shell carbonate, archaeologists are able to identify the season, or seasons of bivalve collection (Jew et al 2013;Hallmann et al 2009;Deith 1986;Killingley 1981;Shackleton 1973) and interpret long-and short-term settlement patterns (Prendergast and Schöne 2017;Burchell et al 2013). Seasonality can also be determined through the analysis of sub-annual and annual growth patterns by measuring the distance between seasonally deposited lines (Carré et al 2009;Milner 2001;Lightfoot et al 1993).…”

In a rapidly changing world, maintenance of the good health of the marine environment requires a detailed understanding of its mechanisms of change, and the ability to detect early signals of a shift away from the equilibrium state that we assume characterized it before there was any significant human impact. Given that instrumental measurements of the oceans go back no further than a few decades, the only way in which we can assess the long-term baseline variability that characterizes the pre-perturbation equilibrium state of the marine environment is by the use of proxy records contained in stratified or layered natural archives such as corals, fish otoliths and bivalve mollusc shells. In this chapter we will look at the ways in which the environmental signals recorded in the shells of bivalve molluscs can be used to shed light on marine variability both in the present and over past centuries and millennia, and specifically how they can be used to study marine climate, the marine environment and the economic and cultural history of the relationship between humans and the oceans. The chapter is divided into two parts: section one describes the morphological, geochemical and crystallographic techniques that are used to obtain information from the shells, while section two covers the use of bivalve shells in a wide range of
