DOI: 10.1002/2016ms000686
Abstract: Depth to bedrock serves as the lower boundary of land surface models, which controls hydrologic and biogeochemical processes. This paper presents a framework for global estimation of depth to bedrock (DTB). Observations were extracted from… read more here.

DOI: 10.1002/2017gl073599
Abstract: The shape of the bedrock underneath Alpine glaciers bears vital information on the erosional mechanism related to the flow of ice. So far, several geophysical exploration methods have been proposed to map the bedrock topography… read more here.

DOI: 10.1002/ecy.2741
Abstract: Global ecosystem models suggest that bedrock nitrogen (N) weathering contributes 10-20% of total N inputs to the natural terrestrial biosphere and >38% of ecosystem N supplies in temperate forests specifically. Yet, the role of rock… read more here.

DOI: 10.1002/esp.4954
Abstract: Understanding the extent to which local factors, including bedrock and structure, govern catchment denudation in mountainous environments as opposed to broader climate or tectonic patterns provides insight into how landscapes evolve as sediment is generated… read more here.

DOI: 10.1002/esp.4996
Abstract: Sediment supply (Qs) is often overlooked in modelling studies of landscape evolution, despite sediment playing a key role in the physical processes that drive erosion and sedimentation in river channels. Here, we show the direct… read more here.

DOI: 10.1016/j.apgeochem.2020.104794
Abstract: Where carbonate bedrock aquifers are overlain by glacial sediments, these sediments control the locations and geochemical signatures of recharge to the bedrock groundwater system. In these settings, geochemical and isotopic tracer tools may be rendered… 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.
