This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Six dendrochronologically dated site chronologies together cover 2345 years between 6703 and 3403 BC. The gaps in between are 6 to 550 years long. Additionally, a floating chronology of 309 years, containing 30 trees, was radiocarbon-dated to the beginning of the 7th millennium cal BC. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations. Tree dying-off phases, which indicate water level rise at the site, mostly in context of the local fen–bog transition, are evident for ca. 6600–6450, ca. 6350–5750, ca. 5300–4900, ca. 4700–4550, ca. 3900–3850, ca. 3700–3600, ca. 3500–3450 and ca. 3400 BC. The spatial distribution of the dated in situ trees illustrates the phase-wise expansion of raised bog over fen peat at the site. The documented bog expansion pulses likely correspond to climatic wet sifts."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2018"],["dc.identifier.doi","10.5194/cp-14-85-2018"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15189"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15121"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.orgunit","Abteilung Palynologie und Klimadynamik"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0"],["dc.title","Dendrochronologically dated pine stumps document phase-wise bog expansion at a northwest German site between ca. 6700 and ca. 3400 BC"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

It was dated with the help of the previously constructed bog-oak chronology of Northwest Germany, the older part of which in turn has been dated using the pine chronology (Fig. 2), now covering from 6628 to 6178 BC additional to the previous span of 6069 BC to 931 AD. Compared to the oaks, chronology construction required large numbers of samples of the short-lived pine trees, many of which remained undated or dated relatively only. The dendrochronological process, which at times delivered a multitude of floating chronology fragments, was complemented by a number of radiocarbon dates. Preceding and following the calendar-dated pine chronology, there are radiocarbon dated floating chronologies. This pine record partly dates back to the beginning of the 9th millennium BC and documents environmental conditions during the early Holocene. It also shows the potential of the chronology to be extended further into the past. The Northwest German pine chronology has since been the base for dating i.a. archaeological finds, such as Neolithic wooden bog trackways. Moreover, the peat-preserved pines have proved to be valuable in palaeoenvironmental research, as they grew at sites where they were sensitive to hydrological changes. Particularly the climate-related advances of raised bog are well reflected in the material."],["dc.description.sponsorship","German Research Foundation DFG [LE 1805/1-2, FR877/16-1, HA4438/1]"],["dc.identifier.doi","10.1127/zdgg/2016/0042"],["dc.identifier.isi","000397029000003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/43126"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1860-1804"],["dc.relation.orgunit","Abteilung Palynologie und Klimadynamik"],["dc.title","The Gottingen tree-ring chronologies of peat-preserved oaks and pines from Northwest Germany"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
