The transfer of radiocarbon into the ocean can be favoured in some regions (COC levels of the estuary reflect a mix between ocean waters and freshwater.How does ocean radiocarbon concentration vary over space and time?
Forensic anthropologists at The University of Arizona took advantage of this fact in a recent study funded by NIJ.
Radiocarbon dating is a technique used in diverse disciplines including environmental science and archaeology.
In the geosciences, the processes by which radiocarbon is produced and cycled through the oceans, atmosphere, and biosphere are broadly understood but there is significant variability in radiocarbon concentrations over space and time.  present the latest status of research on the marine radiocarbon reservoir.
The Earth’s carbon reservoirs are distributed within the lithosphere, hydrosphere, and biosphere.
In fact, even tiny microbes are carbon reservoirs, but scientists tend to group small reservoirs into larger categories (e.g., ocean, atmosphere, biosphere), important at the global scale.
The researchers wanted to find out if they could identify a person's year of birth or year of death using precise measurements of carbon-14 levels in different post-mortem tissues.
