The time series can be compared directly # with the long and continuous records from the ice and the ocean to understand the rates of change and thresholds # in the response of the continental ecosystems to abrupt forcing events. # Provided Keywords: Eifel, Flood events, Ice core tuning, Laminated lake sediments, Maar lakes, MIS 3, Paleoclimate, Plant macroremains, Pleistocene, Pollen, Sedimentary archives, Tephrochronology, Total carbon, Vegetation # #-------------------- # Publication # Authors: Michael W.

All sediment cores are dated by 14C and tuned to the Greenland interstadial succession. Tephra layers were characterized by the petrographic composition of basement rock fragments, glass shards and characteristic volcanic minerals. 10 marker tephra, including the well-established Laacher See Tephra and Dümpelmaar Tephra can be identified in the cores spanning the last glacial cycle. Older cores down to the beginning of the Elsterian, show numerous tephra sourced from Strombolian and phreatomagmatic eruptions, including the 40Ar/39Ar dated differentiated tephra from Glees and Hüttenberg. In total, at least 91 individual tephra can be identified since the onset of the Eifel volcanic activity at about 500,000 b2k, which marks the end of the ELSA tephra stack with 35 Strombolian, 48 phreatomagmatic and 8 tephra layers of evolved magma composition. Many eruptions cluster near timings of the global climate transitions at 140,000, 110,000 and 60,000 b2k. In total, the eruptions show a pattern, which resembles timing of phases of global sea level and continental ice sheet changes, indicating a relation between endogenic and exogenic processes. #------------------ # Funding_Agency # Funding_Agency_Name: Stiftung Rheinland-Pfalz für Innovation # Grant: 15212-386261/724 #------------------ # Site_Information # Site_Name: Eifel # Location: Europe>Western Europe>Germany # Country: Germany # Northernmost_Latitude: 50.16 # Southernmost_Latitude: 50.16 # Easternmost_Longitude: 6.83 # Westernmost_Longitude: 6.83 # Elevation: ~400 m #------------------ # Data_Collection # Collection_Name: ELSA2016tephra # Earliest_Year: 220000 # Most_Recent_Year: 11000 # Time_Unit: Cal.
