Marine or estuarine radiocarbon reservoir corrections for mollusks? A case study from a medieval site in the south of England

Mollusk shells are frequently radiocarbon dated and provide reliable calibrated age ranges when the regional marine reservoir correction is well-established. For mollusks from an estuarine environment the reservoir correction may be significantly different than the regional marine reservoir correction due to the input of bedrock or soil derived carbonates. Some mollusk species such as oysters are tolerant of a significant range of salinities which makes it difficult to determine which reservoir correction is appropriate. A case study is presented of an anomalous radiocarbon age for an oyster shell paint dish found in the fabric of the ruined nave walls of St Mary's Church, Shoreham-by-Sea, West Sussex, England. Stable isotopes (delta O-18 and delta C-13) were used to establish the type of environment in which the oyster had lived. Paired marine and terrestrial samples from a nearby medieval site were radiocarbon dated to provide an appropriate reservoir correction.

EAP759: Survey of Bengal puthis discovered in Sundarbans, South 24 Parganas, West Bengal

This project surveyed the Sundarban Anchalik Sangrahasala Collection housed in the Sundarban area of South 24 Parganas District of West Bengal.
The survey includes the historical background to the collection, the challenges the team faced, the listing for the manuscripts that were digitised, and an inventory of the manuscripts housed at Sundarban Anchalik Sangrahasala (pages 18-35)
Further details about the project can be found on the EAP website, as well as the digital versions of manuscripts that were copied.
