It is therefore possible to study the influence of the freshwater reservoir effect on radiocarbon dates in the Limfjord over long time scales.

Details on this study area are provided in [This section describes the sample collection, chemical preparation, and measurement techniques.

Depending on size, the outer 10–25% of the shell was dissolved with 1M HCl.

The most common cause of high apparent ages in freshwater systems is the presence of dissolved ancient carbonates, leading to the so-called hardwater effect.The moraines have calcium carbonate contents of up to 20% ([] for details on the study area).In the same region, the impact of the freshwater reservoir effect on radiocarbon dating of pottery was studied.Here, freshwater influence causes reservoir ages to vary between 250 and 700 C years during the period 5400 BC - AD 700.The examples in this study show clearly that the freshwater reservoir effect can seriously corrupt radiocarbon dating at inland sites.

This study focuses on the part between 4 cm bpsl which was subsampled at 1–2 cm depth intervals.
