Dendrochronological dates of subfossil pines (Pinus sylvestris L.), relative dates of floating chronology, and peat stratigraphy from site "TOMO_south" at Totes Moor, northwest Germany

This is a dendrochronological investigation of a mire site densely covered by peat-preserved pine stumps (Pinus sylvestris). The site in the northwest German Tote Moor revealed to feature trees from various Holocene millennia. The dendrochronologically dated site chronology covers 2345 years between 6703 BC and 3403 BC, containing 5 gaps between 6 and 550 years in length. It consists of 477 trees. A floating chronology segment of 309 years, containing 30 trees, was radiocarbon dated to the beginning of the 7th millennium cal. BC. The tree ring data from the site documents environmental changes over a larger period of time. Furthermore, the site is covered densely with in situ tree stumps from the fen-bog transition. This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations.

本研究针对一处被泥炭保存的欧洲赤松（Pinus sylvestris）树桩密集覆盖的泥炭地遗址开展树木年代学调查。该遗址位于德国西北部的托特摩尔（Tote Moor），其树木年代涵盖全新世多个千年时段。经树木年代学定年的遗址年代序列跨度达2345年，时间范围为公元前6703年至公元前3403年，其间存在5个长度介于6至550年的断档，共包含477株树木样本。一段时长309年、涵盖30株树木的浮动年代序列段，经放射性碳定年并校准后，被确定为公元前7千纪初期。该遗址的树木年轮数据记录了较长时段内的环境变化。此外，遗址还密集覆盖着来自沼泽-泥炭沼过渡带的原位树桩，这一条件可为本次案例研究中基于212株原位树桩的泥炭地发育时空重建工作提供便利。研究还开展了额外的泥炭地层学调查，并在多个测点测定了海拔高程（above sea level, a.s.l.）。
