CENA: Catastrophic Events at the End of the Last Ice Age and Their Impact on Mountain Lake Ecosystems in North America and Europe

Methods:

Lithological and sedimentological characterization of lake sediment cores
¹⁴C dating and age-depth modelling
Geochemical characterization of sediments samples (XRF; μXRF; EDAX; ICP-MS; SEM; EPMA; EDS-WDS; C and N stable isotopes; analyses of C, H, N, S ratios; fractionation of sensitive elements such as Fe, Al, P; loss-on-ignition; identification and analyses of potential tephras)
Geophysical characterization of sediment samples (magnetic susceptibility and magnetic remanence; magnetic and non-magnetic separation of MSPs)
Micropaleontological techniques (analyses of remains of aquatic invertebrate fauna – chironomids and cladocerans; pollen analysis; diatom analysis; plant macro-remain analysis)
