Subregional inversion of North African dust sources
(AMER Geophysical Union, 2016)
The emission of mineral dust aerosols in arid and semiarid regions is a complex process whose representation in atmospheric models remains crude, due to insufficient knowledge about the aerosol lifting process itself, the ...
Silicic volcanism triggered by increased denudation rates in the Quaternary Andean arc of central Chile between 33 degrees 50 '-34 degrees 30 ' S
(ELSEVIER, 2020)
In central Chile (33 degrees 50'-34 degrees 30'S), the Quaternary arc records a distinctive episode of silicic volcanism (SiO2 >70 wt%) that occurred during latest Pleistocene (0.1-1 Ma). This episode is recorded in several ...
DC resistivity investigation in a fractured aquifer system contaminated by leachate from an old dump
(Inst Geophysics Unam, 2017-10-01)
The dumps are areas of final disposal of solid wastes directly into the soil, with no technical criteria or collecting systems of gases or liquids. A large part of Brazilian municipalities have used this extreme damaging ...
A simple method inspired by empirical mode decomposition for denoising seismic data
(Society of Exploration Geophysicists, 2015-12)
We developed a new and simple method for denoising seismic data, which was inspired by data-driven empirical mode decomposition (EMD) algorithms. The method, which can be applied either as a trace-by-trace process or in ...
