Samples for studying the Limfjord were obtained from a sediment core.Aquatic macrophytes and animals were collected at the same sites as the water samples. No visible carbonate encrustations were found on the aquatic plants. Collagen was extracted from some modern fishbones, as this is the material used for analyses of archaeological bones.Of particular interest and complexity are the so-called reservoir effects, which result in apparent ages that are too old. This is of particular concern to archaeologists, as aquatic resources were an important contribution to human nutrition in Northern Europe, from Mesolithic hunter-gatherer-fishers to medieval Christians.One of the basic assumptions in radiocarbon dating is that a sample incorporates carbon in equilibrium with the atmosphere. The marine reservoir effect is well-acknowledged among archaeologists, although the knee-jerk subtraction of 400 years from radiocarbon dates of marine samples might be too simplistic in some cases.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.As Kilen was naturally protected from strong currents, storms and wave action in the past, a continuous sediment sequence has been preserved.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.

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