Quantifying weathering on variable rocks, an extension of geochemical mass balance: Critical zone and landscape evolution
Sign Up to like & getrecommendations! Published in 2017 at "Earth Surface Processes and Landforms"
DOI: 10.1002/esp.4212
Abstract: We present a statistical model of soil and rock weathering in deep profiles to expand the capacity to assess weathering to heterogeneous bedrock types, which are common at the Earth's surface. We developed the Weathering… read more here.

DOI: 10.1007/s10533-017-0299-8
Abstract: Several decades of research in alpine ecosystems have demonstrated links among the critical zone, hydrologic response, and the fate of elevated atmospheric nitrogen (N) deposition. Less research has occurred in mid-elevation forests, which may be… read more here.

DOI: 10.1007/s11368-019-02409-0
Abstract: The Earth’s critical zone encompasses a suite of interconnected processes in the near-surface lithosphere, pedosphere, biosphere, atmosphere, and hydrosphere (Brantley et al. 2007; Lin 2010) (Fig. 1). Processes and interactions both within and between these… read more here.

DOI: 10.1016/j.ancene.2018.04.002
Abstract: Abstract Expansion and intensification of managed landscapes for agriculture have resulted in severe unintended global impacts, including degradation of arable land and eutrophication of receiving water bodies. Modern agricultural practices rely on significant direct and… read more here.

DOI: 10.1038/s41598-019-40819-9
Abstract: As bedrock weathers to regolith – defined here as weathered rock, saprolite, and soil – porosity grows, guides fluid flow, and liberates nutrients from minerals. Though vital to terrestrial life, the processes that transform bedrock… read more here.
