Bâlea Lake coring campaign
Between April 16 and 18 the sediment collection campaign took place at Bâlea Lake, in Făgăraș Mountains. This field campaign aimed to identify the connection between the energetic potential of the geomorphological processes and the sedimentation rates found in the stratigraphic sequences of the lake, as well as to identify the impact of human activities in the area and variations in the sedimentation rates from the early Holocene to the present times. Thus, through the Cobra TT corer and using a number of 20 segments, 9 meters of lake sediment were collected, requiring the penetration of the ice and snow layer (about 2-2.5 m), as well as the addition of new segments to reach the bottom of the lake (10 m). At the depth of 9 m, the crystalline schist (base rock) was reached, which means that the entire evolution of the lake (from the retreat of the Pleistocene glaciers to the present) can be rebuilt. For the accuracy of the paleo-reconstruction, grain size analysis, loss on ignition (LOI), AMS C14 dating, geochemistry analyses and pollen determinations. will be performed. This field campaign was carried out within the framework of ClimaLand project, with the support of the Institute of Geography of the Romanian Academy and the Bâlea Mountain Rescue Base.
