Palynological data for the Late Glacial and Holocene (14.5-0 ka BP) from Furamoos, Southern Germany.

ABSTRACT: We here present high-resolution palynological data from the Füramoos peat bog, located in the alpine foreland of Southern Germany. The data represent raw pollen counts of major arboreal pollen as well as agricultural indicator taxa for the Late Glacial and Holocene (14.5 ka BP to present) at Füramoos with an average temporal resolution of 100 years (50 years during critical intervals). The data are also provided as percentages, which are calculated based on the total sum of pollen grains, excluding pollen grains of sedges (Cyperaceae) and strictly aquatic taxa. The data yield insight into the vegetation dynamics in Central Europe in response to climatic and anthropogenic forcing, which are an integral part of the original research article (Kern et al., 2021). Considering its high temporal resolution and the robust age-depth model, the dataset is ideally suited to be included in regional syntheses of vegetation dynamics in Central Europe from the Late Glacial onwards. In addition to the data, we provide a detailed description of the Füramoos site and detail the palynological processing and analysing techniques used.

Project description:Climate is currently warming due to anthropogenic impact on the Earth's atmosphere. To better understand the processes and feedbacks within the climate system that underlie this accelerating warming trend, it is useful to examine past periods of abrupt climate change that were driven by natural forcings. Glaciers provide an excellent natural laboratory for reconstructing the climate of the past as they respond sensitively to climate oscillations. Therefore, we study glacier systems and their behavior during the transition from colder to warmer climate phases, focusing on the period between 15 and 10 ka. Using a combination of geomorphological mapping and beryllium-10 surface exposure dating, we reconstruct ice extents in two glaciated valleys of the Silvretta Massif in the Austrian Alps. The mountain glacier record shows that general deglaciation after the Last Glacial Maximum (LGM) was repeatedly interrupted by glacier stabilization or readvance, perhaps during the Oldest Dryas to Bølling transition (landform age: 14.4 ± 1.0 ka) and certainly during the Younger Dryas (YD; 12.9-11.7 ka) and the Early Holocene (EH; 12-10 ka). The oldest landform age indicates a lateral ice margin that postdates the 'Gschnitz' stadial (ca. 17-16 ka) and predates the YD. It shows that local inner-alpine glaciers were more extensive until the onset of the Bølling warm phase (ca. 14.6 ka), or possibly even into the Bølling than during the subsequent YD. The second age group, ca. 80 m below the (pre-)Bølling ice margin, indicates glacier extents during the YD cold phase and captures the spatial and temporal fine structure of glacier retreat during this period. The ice surface lowered approximately 50-60 m through the YD, which is indicative of milder climate conditions at the end of the YD compared to its beginning. Finally, the third age group falls into a period of more substantial warming, the YD-EH transition, and shows discontinuous glacier retreat during the glacial to interglacial transition. The new geochronologies synthesized with pre-existing moraine records from the Silvretta Massif evidence multiple cold phases that punctuated the general post-LGM warming trend and illustrate the sensitive response of Silvretta glaciers to abrupt climate oscillations in the past.
