The main use of carbon dating, as you may already know, is to determine roughly how old something is. It has been used to date the Dead Sea Scrolls, the Pyramids of Egypt, mummies, bones, and pretty much anything 50, years and younger. Along with that, carbon dating is used to study climate change and show that humans have increased the concentration of carbon dioxide in the atmosphere by burning fossil fuels.

Both archaeology and Earth sciences had their share in the establishment of 14C dating. The first 14C ages produced on archaeological and geological samples.
Following this maximum, the ice sheet began to diminish in size. Retreat was rapid in some sectors, but was punctuated by still-stands and readvances in other sectors. Geochronology of CIS retreat is key for understanding the pace and style of this deglaciation, and for testing hypothesized feedbacks between the changing ice sheet and the ocean, atmosphere, and solid earth.
One method of reconstructing ice sheet retreat relies on radiocarbon ages of immediate post-glacial organic material. Such ages are minima for deglaciation and are often utilized to infer the timing of ice sheet retreat. The data were collected from published literature. This information is useful for validating numerical models of the CIS, for connecting CIS evolution to climate change, and for reconstructing late Pleistocene environments of the Pacific Northwest.
The data and references are stored in the Open Quaternary Dataverse Gombiner, Age data is available as an excel spreadsheet. This dataset will be updated as new data become available or known to the author, but past versions will remain accessible in the Dataverse. Note that to download the.
