It is a common practice to reconstruct glacier activity from lake sediment records. Such an approach is generally applied to proglacial lakes. However in some cases, terrigenous inputs from glaciated areas are dominating enough to make distant sedimentary basins sensitive to glacier fluctuations. This is the case in Lake Bourget, located on the...
Two well-dated ca Holocene-long sedimentary sequences from deepest parts of Lake Bourget provide new insights onto the evolution of erosion patterns at a regional scale in NW European Alps. The combination of high resolution geochemistry e XRF core scanning, calibrated by 150 punctual measurements e and isotope geochemistry ( 3Nd) of the...
Multiproxy analyses were performed on core MS27PT recovered in hemipelagic sediments deposited on the Nile margin in order to reconstruct Nile River palaeohydrological fluctuations during the last 100,000 years. The strontium and neodymium isotope composition of the terrigenous fraction and the major element distribution reveal large and abrupt...
In this paper we present a review of a ca. 10-years research effort (1-9) aiming at reconstructing floods dynamicsin in French Alps through the Holocene, based on lake sediment records. We will particularly discuss how such geological records can be considered as representative of past climate. This implies a wise interpretation of data in...
We review the scientific efforts over the last decades to reconstruct erosion from continuous alpine lake sediment records. We focused both on methodological issues, showing the growing importance of non-destructive high resolution approaches (XRF core-scanner) as well as progresses in the understanding of processes leading to the creation of...
In this paper we review the scientific efforts that were led over the last decades to reconstruct geomorphic patterns from continuous alpine lake sediment records. Whereas our results point a growing importance of humans as erosion forcing factors, we will focus here on climate-related processes. Our main dataset is made of a regional approach...
