A cold laboratory hyperspectral imaging system to map grain size and ice layer distributions in firn cores [PDF]

The Cryosphere
The Greenland and Antarctic ice sheets are covered in a layer of porous firn. Knowledge of firn structure improves our understanding of ice sheet mass balance, supra- and englacial hydrology, and ice core paleoclimate records.

Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model [PDF]

, 2018
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary record in rift basins, we study the
