Stable isotopes and sclerochronology of the bivalve Mesodesma donacium: Potential application to Peruvian paleoceanographic reconstructions

Oxygen isotope ratios in the shell of <i>Mytilus edulis</i>: archives of glacier meltwater in Greenland?

“…Many calcitic bivalve species precipitate their shells in oxygen isotopic equilibrium with the ambient water (Chauvaud et al, 2005;Freitas et al, 2012;Hickson et al, 1999) In both equations T is the temperature in K and α is the isotope fractionation factor: (Freitas et al, 2006;Goewert et al, 2007;Versteegh et al, 2010a).…”

“…corals (Swart, 1983;Watanabe et al, 2011), coralline algae (Halfar et al, 2008;Williams et al, 2011), land snails (Goodfriend and Ellis, 2002;Yanes et al, 2011), freshwater snails (Abell and Hoelzmann, 2000;Stevens et al, 2012), freshwater bivalves (Kaandorp et al, 2003;Versteegh et al, 2010bVersteegh et al, , 2011 and marine bivalves (Jones and Quitmyer, 1996;Santos et al, 2012;Schöne et al, 2005). The oxygen isotope composition (δ 18 O values) of marine bivalves is often used as a proxy for temperature (Carré et al, 2005;Wanamaker et al, 2011). It can, however, also be applied to reconstruct water δ 18 O (δ 18 O w ) values (Freitas et al, 2012;Khim, 2002), which usually directly relate with salinity (Ingram et al, 1996).…”

Oxygen isotopes in Molluscan shell: Applications in environmental archaeology

“…This is particularly advantageous for studying short-term climate variability (e.g. interdecadal phenomena such as El Niň o Southern Oscillation (ENSO); Carré et al 2005aCarré et al , 2005b and for filling in the gaps often left by other commonly used proxies such as diatoms, ostracods and foraminifera that can be biased towards an average of a particular season over decades. Furthermore, this level of detail is essential when trying to assess cultural-climatic links in the past, as changing seasonal conditions can be extremely detrimental to societies, often leading to long-term climate stress and in extreme cases abandonment of settlements, migration or societal collapse (e.g.…”

“…Intra-shell variations are thought to record past seawater salinity and/or temperature (e.g. Kennett and Voorhies 1996;Klein et al 1997;Aguire et al 1998;Carré et al 2005aCarré et al , 2005bMannino et al 2008;Stephens et al 2008;Patterson et al 2010;Azzoug et al 2012), with some studies using modern environmentshell δ…”

“…Burman and Schmitz 2005;Andrus 2011), which means that environmental and climatic inferences are directly applicable to the period of site occupation and often form the major drivers of marine resource availability and subsequently patterns of human subsistence (e.g. Kennett and Voorhies 1996;Mannino et al 2011).
