متن کاملPrecise Temporal Correlation of Holocene Mollusk Shells Using Sclerochronology
Annual growth bands of mollusk shells record several types of paleoenvironmental information, including geochemical proxies for water properties and morphological characteristics of growth and mortality. Sclerochronology, the marine counterpart of dendrochronology, offers a way to link individual shells together to form long continuous records of such parameters. It also allows for precise dati...
متن کاملUranium 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 کاملAntimicrobial Packaging: Potential vs. Reality—A Review
THE safety and quality of the food supply has gained significant attention in recent years, yet increasing concerns over recalls and ingredient sourcing trouble many consumers [12]. These concerns lead to a need for more effective safety regulations as well as better systems for maintaining food quality. However, there is also an increase in consumer desire for natural, local and organic produc...
متن کاملConstruction of statistically reliable sclerochronology using subfossil shells of river pearl mussel
Sclerochronology is based on series of skeletal growth records that have been correctly aligned in time. These chronologies have so far been derived from living bivalves and corals. Here we demonstrate the possibility of constructing the sclerochronology from a suite of river pearl mussel (Margaritifera margaritifera (L.)) shells with unknown but at least partly overlapping geological age. Subs...
