本文的目的是讨论由于淡水和海洋水库的影响（FRE和MRE，分别）在波罗的海东南部的放射性碳测年偏移。这里展示了来自立陶宛沿海和内陆亚新石器时代、新石器时代和青铜时代遗址以及两个中石器-新石器时代墓地的36个14 C年代。加速器质谱（AMS）的日期，有时成对或三倍，已获得各种来源的样品，食品结壳，或可见的烧焦沉积物粘附在陶瓷容器壁的表面也定年和稳定同位素信号的调查。研究结果表明，在新石器时代和亚新石器时代的陶瓷器皿中加工的食物中含有重要的淡水成分。在Spiginas和Donkalnis墓地（公元前6300-1900 cal）的有蹄类动物和人类骨骼的配对测年并不表明FRE，尽管人类骨骼胶原蛋白的稳定同位素数据强烈表明饮食中有大量淡水食物的输入。据估计，Šventoji古泻湖在公元前3000 cal左右的FRE为320-510年。与此同时，库尔尼亚泻湖的FRE可能更大，这是由现代梭子鱼（981 ± 30 BP）和鲷（738 ± 30 BP）骨骼的大表观14 C年龄以及Nida（公元前3500-2500 cal）的“食物地壳”偏移（650-530年）所暗示的。根据Nida和Šventoji的海豹骨骼和陆地样品的年代偏移，估计Littorina海东南海岸的MRE为190 ± 43年。由于迄今为止的工作有限，Kretuonas湖的任何FRE仍然不确定。
The aim of this article is to discuss radiocarbon dating offsets due to freshwater and marine reservoir effects (FRE and MRE, respectively) in the southeastern Baltic. Thirty-six 14C dates from Lithuanian coastal and inland Subneolithic, Neolithic, and Bronze Age sites as well as two Mesolithic-Neolithic cemeteries are presented here. Accelerator mass spectrometry (AMS) dates, sometimes paired or tripled, have been obtained on samples of various origin, foodcrusts, or visible charred deposits adhering to the surfaces of ceramic vessel walls were also dated and investigated for stable isotope signals. The results argue for a significant freshwater component in the food processed in ceramic vessels during the Subneolithic and Neolithic. Paired dating of ungulate and human bones at the Spiginas and Donkalnis cemeteries (6300–1900 cal BC) does not suggest an FRE, although stable isotope data on human bone collagen strongly suggest a large input of freshwater food in the diet. An FRE in the order of 320–510 yr was estimated for the Šventoji paleolagoon around 3000 cal BC. At the same time, the FRE of the Curonian Lagoon could be larger as implied by large apparent 14C ages of modern pike-perch (981 ± 30 BP) and bream (738 ± 30 BP) bones as well as “foodcrust” offsets (650–530 yr) at Nida (3500–2500 cal BC). An MRE of 190 ± 43 yr was estimated for the southeastern coast of the Littorina Sea according to offsets between dates of seal bones and terrestrial samples at Nida and Šventoji. Any FRE at Lake Kretuonas remains uncertain due to the limited work to date.
