Reservoir effects should therefore be considered whenever food remains on pottery or the bones of omnivores are radiocarbon dated - irrespective of the site’s distance to the coast.Throughout the entire history of radiocarbon dating, new sources of error have appeared, have been examined, and corrections have been found. This type of sample is called samples) or in freshwater systems such as lakes and rivers.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 aim of this study is to examine the order of magnitude and degree of variability of the freshwater reservoir effect over short and long timescales.HCl-pretreatment was therefore not considered necessary. A modified Longin-procedure with ultrafiltration was used []) in two parallel boreholes at a water depth of 390 cm below present sea level (bpsl).The sediments consist of homogenous grey-brown marine clay gyttja.Depending on size, the outer 10–25% of the shell was dissolved with 1M HCl.Possible organic remains were removed with KMn OFor the sediment core, an age model was calculated based on 13 radiocarbon dates on macrofossils of unequivocally terrestrial origin.

Mesolithic pottery, maybe the earliest in that region, was found at the sites Kayhude at the Alster and Schlamersdorf at the Trave. Today, after the construction of a dam, Kilen is a brackish embayment.
