Uranium in aragonitic marine bivalve shells
a r t i c l e i n f o Uranium concentrations in foraminiferal and coral skeletons track oceanic [CO 3 2 − ] and can be useful as a proxy of ocean acidification, but this pH proxy is yet to be investigated in bivalves. Two Saxidomus giganteus shells from the industrialized Puget Sound (WA, USA) and one from the more pristine Kodiak Island (AK, USA) were sampled through ontogeny for U/Ca using la...

متن کاملArchitecture of crossed-lamellar bivalve shells: the southern giant clam (Tridacna derasa, Röding, 1798)
Tridacna derasa shells show a crossed lamellar microstructure consisting of three hierarchical lamellar structural orders. The mineral part is intimately intergrown with 0.9 wt% organics, namely polysaccharides, glycosylated and unglycosylated proteins and lipids, identified by Fourier transform infrared spectrometry. Transmission electron microscopy shows nanometre-sized grains with irregular ...

متن کاملIs the umbo matrix of bivalve shells (Laternula elliptica) a climate archive?
Heavy metal accumulation into bivalve soft tissues has received increasing interest in recent years with respect to biomonitoring of environmental change including pollution. To a lesser extent, accretion of elements from the environment into bivalve hard structures (shells) has been investigated, although the importance of the shells as environmental archives has been acknowledged. Here we rep...
