New source-to-sink approach in an arctic catchment based on hyperspectral core-logging (Lake Linné, Svalbard)
Résumé
Hyperspectral core logging is a rapid and non-destructive technique in palaeolimnology.
The technique is able to track lacustrine sediment sources.
Environmental changes in the catchment-to-lake sedimentation and spatial sources are identified.
This new method enables the fingerprinting of sedimentary sources with and/or without field samples.
Data calibration allows reconstructing total organic carbon concentrations on several cores, at an unprecedented resolution.
