DOI: 10.1007/s11629-017-4695-2
Abstract: In glacierized catchments, glacier runoff typically shows a strong diurnal cycle in the ablation season (June-September). To elucidate the effect of these processes on the chemical weathering, fresh snowfall and water samples were collected and… read more here.

DOI: 10.1016/j.epsl.2020.116517
Abstract: Abstract Previously glaciated landscapes are often covered with glacial sediments with poorly sorted particles. The thickness of glacial sediments can reach hundreds of meters. These sediments, which have experienced high intensity erosion through glacial transportation,… read more here.
