“…This relation is nearly linear between 5 and 30°C, as demonstrated empirically by Epstein et al (1951) and Epstein and Lowenstam (1953). Therefore, a mollusc shell from an environment with rather constant salinity and a distinct annual temperature cycle will show an oscillating pattern of d 18 O along the major growth axis (see examples in Krantz et al 1987;Richardson 2001;Lomovasky et al 2002). Five representative specimens (two males of 50 and 170 mm SL and three females of 80, 161, and 198 mm SL) of Z. dufresnei sampled in Spring 2001 were selected for isotope analysis.…”

“…Acetate peels were made of polished and etched sections to confirm the pattern found (Rhoads and Lutz, 1980). Stable oxygen isotope ratios (y 18 O) can be used to confirm seasonality of growth in calcareous species (see Forester et al, 1973;Krantz et al, 1987;Wefer and Berger, 1991). Following previous attempts by Jones et al (1983), Krantz et al (1984), Donner and Nord (1986), Brey and Mackensen (1997) and others, we used y 18 O in the shell to test whether growth rings are formed annually in E. exalbida.…”

Growth, mortality and productivity of the hard clam Eurhomalea exalbida from Ushuaia Bay, Beagle Channel, were investigated. The parameters of the von Bertalanffy growth function were estimated to be H l = 74 mm, K = 0.18 y À 1 , t 0 = 0.15 y. Maximum individual production amounted to 2.74 g shell-free wet mass (SFWM) at 49.5 mm shell height. Animals between 40 mm and 70 mm shell height contributed most to overall population somatic production P of 134 g SFWM m À 2 y À 1 . Mean annual biomass B amounted to 1123 g SFWM m À 2 y À 1 . Annual P/B ratio and mortality rate Z were estimated to be 0.12 y À 1 and 0.14 y À 1 , respectively. Slow growth and low turnover make this population less suitable for sustainable commercial exploitation. D

“…However, the promise of AMS dating artifacts made from portions of a whole shell comes with a devil's bargain; in exchange for a date on a small object, dating uncertainties may be introduced by the short-term variation in the mollusk's metabolism, habitat, and local 14 C reservoir (e.g. Dye 1994;Ingram 1998;Keith et al 1964;Kennett et al 1997;Killingley and Berger 1979;Krantz et al 1987Krantz et al , 1989Wefer and Berger 1991). Variations that are normally averaged in larger aggregate samples are potentially magnified by the random selection of a narrow period of growth.…”

We demonstrate variable radiocarbon content within 2 historic (AD 1936) and 2 prehistoric (about 8200 BP and 3500 BP) Mytilus californianus shells from the Santa Barbara Channel region, California, USA. Historic specimens from the mainland coast exhibit a greater range of intrashell variability (i.e. 180–240 14C yr) than archaeological specimens from Daisy Cave on San Miguel Island (i.e. 120 14C yr in both shells). δ13C and δ18O profiles are in general agreement with the up welling of deep ocean water depleted in 14C as a determinant of local marine reservoir correction (ΔR) in the San Miguel Island samples. Upwelling cycles are difficult to identify in the mainland specimens, where intrashell variations in 14C content may be a complex product of oceanic mixing and periodic seasonal inputs of 14C-depeleted terrestrial runoff. Though the mechanisms controlling ΔR at subannual to annual scales are not entirely clear, the fluctuations represent significant sources of random dating error in marine environments, particularly if a small section of shell is selected for accelerator mass spectrometry (AMS) dating. For maximum precision and accuracy in AMS dating of marine shells, we recommend that archaeologists, paleontologists, and 14C lab personnel average out these variations by sampling across multiple increments of growth.
