Theoretical Principles and Perspectives of Hyperspectral Imaging Applied to Sediment Core Analysis

Hyperspectral imaging is a recent technology that has been gaining popularity in the geosciences since 1990s, both remote sensing and field or laboratory. Indeed, it allows rapid acquisition of large amount data are spatialized on studied object with low-cost, compact, automatable sensor. This practical article aims to present current state knowledge use hyperspectral for sediment core analysis (core logging). To full potential this type sensor, many points must be considered will discussed obtain reliable quality extract environmental properties cores. used fields (e.g., sensing, artificial intelligence) offers possibilities. The applications literature reviewed under five themes: lake water body trophic status, source-to-sink approaches, organic matter mineralogy studies, sedimentary deposit characterization. Afterward, discussions focused multisensor logger, management, integrated these selection sample areas, other opportunities. Through article, we emphasize applied cores still an emerging tool shows possibilities refining understanding processes.
