“…Measured maximum Ba/Ca values, on the other hand, varied between 3.1-76.1 µmol mol −1 , demonstrating different peak values among shells from a same basket (Table 3). This variability in maximum values is among the largest reported (Barats et al, 2009;Marali et al, 2015), and cannot be explained by averaging error (see Section 4.4).…”

“…Synchronously deposited chemical proxies are useful temporal anchors to combine chronologies across bivalves sampled from the same location (Marali et al, 2015). Our results indicate that the Ba/Ca peaks are likely to occur simultaneously 2.5 weeks to 2.5 months after primary production blooms.…”

“…Barium-to-calcium provides the most consistent elemental ratio signal in bivalve shells: Ba/Ca profiles are characterized by a flat background signal that is periodically interrupted by sharp peaks in a wide range of species across various habitats and latitudes (Stecher et al, 1996;Toland et al, 2000;Vander Putten et al, 2000;Torres et al, 2001;Lazareth et al, 2003;Gillikin et al, 2006Gillikin et al, , 2008Barats et al, 2009;Carroll et al, 2009;Elliot et al, 2009;Thébault et al, 2009a;Marali et al, 2015). Barium-to-calcium ratios have been shown to reflect Ba concentration in ambient seawater (Gillikin et al, 2006;Tabouret et al, 2012;Poulain et al, 2015) that might in some cases be associated with primary productivity.…”

Understanding rapid climate change in the Arctic and its ecosystem implications requires more information on the environment at temporal resolutions and time-periods not available from instrumental records. Such information can be acquired through geochemical proxy records, but sub-annual records are rare. We analyzed shell material of bivalve mollusks (Serripes groenlandicus and Ciliatocardium ciliatum) placed on oceanographic moorings for one year in two Arctic fjords to assess the potential use of shell elemental ratios as environmental proxies.

“…Besides sea water temperature, attempts have been made to reconstruct other environmental parameters, such as redox conditions and palaeoproductivity, based on trace element records in bivalves. Examples of such proxies include elements that are enriched in skeletons of primary producers such as Ba Marali et al, 2017), redox-sensitive elements like Mn (Freitas et al, 2006) and micronutrients such as Zn and Cd, which are known to be taken up into bivalve shells and whose concentration profiles reflect changes in palaeoproductivity (Carriker et al, 1980a;Calmano et al, 1993;Jackson et al, 1993;Wang and Fisher, 1996;Guo et al, 1997). Seasonal records of these proxies are reproducible between different shells in the same environment .…”

An assessment of latest Cretaceous <i>Pycnodonte vesicularis</i> (Lamarck, 1806) shells as records for palaeoseasonality: a multi-proxy investigation

In order to assess the potential of the honeycomb oyster Pycnodonte vesicularis for the reconstruction of palaeoseasonality, several specimens recovered from late Maastrichtian strata in the Neuquén Basin (Argentina) were subject to a multi-proxy investigation, involving scanning techniques and trace element and isotopic analysis. Combined CT scanning and light microscopy reveals two calcite microstructures in P. vesicularis shells (vesicular and foliated calcite). Micro-XRF analysis and cathodoluminescence microscopy show that reducing pore fluids were able to migrate through the vesicular portions of the shells (aided by bore holes) and cause recrystallization of the vesicular calcite. This renders the vesicular portions not suitable for palaeoenvironmental reconstruction. In contrast, stable isotope and trace element compositions show that the original chemical composition of the foliated calcite is wellpreserved and can be used for the reconstruction of palaeoenvironmental conditions. Stable oxygen and clumped isotope thermometry on carbonate from the dense hinge of the shell yield sea water temperatures of 11 • C, while previous TEX H 86

“…It may be possible to use the Ba/Ca ratio in bivalve shells to track the release over time of Ba in the proximity of drill cutting disposal. Marali et al (2016) have measured Ba/Ca ratios in multicentennial A. islandica chronologies from four sites (Gulf of Maine, Iceland, Faroe Islands, and Isle of Man) to show that Ba/Ca shell spikes are synchronous within chronologies, and that this synchroneity is independent of ontogenetic age.…”

Assessments of the impact of construction, operation, and removal of large infrastructures and other human activities on the marine environment are limited because they do not fully quantify the background baseline conditions and relevant scales of natural variability. Baselines as defined in Environmental Impact Assessments typically reflect the status of the environment and its variability drawn from published literature and augmented with some short term site specific characterization. Consequently, it can be difficult to determine whether a change in the environment subsequent to industrial activity is within or outside the range of natural background variability representative of an area over decades or centuries. An innovative approach that shows some promise in overcoming the limitations of traditional baseline monitoring methodology involves the analysis of shell material (sclerochronology) from molluscs living upon or within the seabed in potentially affected areas. Bivalves especially can be effective biomonitors of their environment over a wide range of spatial and temporal scales. A rapidly expanding body of research has established that numerous characteristics of the environment can be reflected in morphological and geochemical properties of the carbonate material in bivalve shells, as well as in functional responses such as growth rates. In addition, the annual banding pattern in shells can provide an absolute chronometer of environmental variability and/or industrial effects. Further, some species of very long-lived bivalves can be crossdated back in time, like trees, by comparing these annual banding patterns in their shells. It is therefore feasible to develop extended timeseries of certain marine environmental variables that can provide important insights into long temporal scales of baseline variability. We review recent innovative work on the shell structure, morphology, and geochemistry of bivalves and conclude that they have substantial potential for use as monitors of environmental variability and the effects of pollutants and disturbance.
