“…7). This observation suggests that Corbicula fluminea halted their growth during winter months, agreeing with published seasonal growth studies on freshwater bivalves (Dettman et al, 1999;Anthony et al, 2001;Goewert et al, 2007 (Freitas et al, 2006) compared both absolute values and the shape of the profiles (Fig. 7).…”

“…Therefore, growth cessation and the onset of shell growth are most likely controlled by a water temperature threshhold. For Corbicula fluminea in this watershed, the temperature threshold is 17°C, which is higher than the temperature threshold of 12°C for unionidae (Dettman et al, 1999;Goewert et al, 2007).…”

“…18 O The development of environmental proxy data provides a means to reconstruct paleoclimate and paleoenvironmental conditions Goewert et al, 2007). We examined whether Corbicula fluminea precipitated its shell in isotopic equilibrium with the ambient environment by comparing measured δ 18 O ar to calculated values (δ 18 O equil ) (Fig.…”

“…Although many species of bivalve precipitate their shells in oxygen isotope equilibrium with the ambient environment (Dettman et al, 1999;Surge et al, 2001;Elliot et al, 2003;Chauvaud et al, 2005), some mollusk display an offset attributed to metabolic processes (e.g., vital effects) (Wefer and Berger, 1991;Fenger et al, 2007). Therefore, we must examine modern and living species to verify isotopic equilibrium before interpreting past climate and environmental conditions preserved in their fossil shells (Goewert et al, 2007). is native to China, Japan and Korea, but now spread in many parts of the world (Asia, Europe, North and South America) and that could therefore provide almost "worldwide" paleoecological archives (Aucour et al, 2003).…”

Stable isotope composition of the modern freshwater bivalve Corbicula fluminea

Bivalve shells have been used in a number of paleoclimate and paleoenvironment studies. In order to investigate oxygen and carbon isotope fractionation between bivalve aragonite and host water, a one year monitoring experiment was conducted. Cooler temperatures seem to cause cessation of growth, suggesting that a threshold temperature may control the onset and cessation of growth. Shell δ 13 C are more negative than predicted δ 13 C values, and we observed that all the specimens showed a trend of lower δ 13 C values with increasing age, this suggests that the incorporation of metabolic carbon is the cause of the negative offset in shell δ 13 C. The variable offset from equilibrium δ 13 C values precludes the direct use of Corbicula fluminea shell in the study of the δ 13 C DIC in ancient bodies of water.

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

et al. 2012

Abstract. Melting of the Greenland Ice Sheet (GrIS) is accelerating and will contribute significantly to global sea level rise during the 21st century. Instrumental data on GrIS melting only cover the last few decades, and proxy data extending our knowledge into the past are vital for validating models predicting the influence of ongoing climate change. We investigated a potential meltwater proxy in Godthåbsfjord (West Greenland), where glacier meltwater causes seasonal excursions with lower oxygen isotope water (δ 18 O w ) values and salinity. The blue mussel (Mytilus edulis) potentially records these variations, because it precipitates its shell calcite in oxygen isotopic equilibrium with ambient seawater. As M. edulis shells are known to occur in raised shorelines and archaeological shell middens from previous Holocene warm periods, this species may be ideal in reconstructing past meltwater dynamics. We investigate its potential as a palaeo-meltwater proxy. First, we confirmed that M. edulis shell calcite oxygen isotope (δ 18 O c ) values are in equilibrium with ambient water and generally reflect meltwater conditions. Subsequently we investigated if this species recorded the full range of δ 18 O w values occurring during the years 2007 to 2010. Results show that δ 18 O w values were not recorded at very low salinities (< ∼ 19), because the mussels appear to cease growing. This implies that M. edulis δ 18 O c values are suitable in reconstructing past meltwater amounts in most cases, but care has to be taken that shells are collected not too close to a glacier, but rather in the midregion or mouth of the fjord. The focus of future research will expand on the geographical and temporal range of the shell measurements by sampling mussels in other fjords in Greenland along a south-north gradient, and by sampling shells from raised shorelines and archaeological shell middens from prehistoric settlements in Greenland.

Abstract:The colonisation of the Mariana Islands in Western Micronesia is likely to represent a long distance ocean dispersal of more than 2000 km, and establishing the date of human arrival in the archipelago is important for modelling Neolithic expansion in Island Southeast Asia and the Pacific. In 2010, Clark et al. published a paper discussing a number of radiocarbon dates from the Bapot-1 site on Saipan Island, but a disparity between charcoal and marine shell (Anadara sp.) results prevented the calculation of a definitive age for the site and left open the possibility that Bapot-1 was first settled as early as 3500 cal BP. Here we present new research using a combination of stable isotope (δ 13 C and δ 18 O) and 14 C information to demonstrate that A. antiquata from the lowest layers of Bapot-1 is affected by hardwaters. These new results indicate human arrival at Bapot-1 occurred around 3200-3080 cal. BP (1250-1130 BC). We recommend a similar isotopic evaluation for other sites in the Marianas that are dated by marine shell.
