🛠 What does an end-to-end open-source stack look like for an independent hydrogeochemical monograph? Doing full-cycle research—from thermodynamic calculations to print-ready LaTeX typesetting—requires a synchronized toolkit. Here is the exact stack: 🧪 Thermodynamics & Analytics: • #PHREEQC 3.7.3 for aqueous speciation&equilibrium modeling. • #Rstats Stack: RedModRphree, ggtern, sf/terra, tidyverse (ETL). 🗺 GIS & Literature Search: • #QGIS for spatial alignment & cartography. • #Recoll for local full-text search across reference databases. 📚 Typesetting & Reproducibility: • #LaTeX2e + #TeXStudio + #JabRef for typography & #BibTeX references. • xtable for automated R-to-LaTeX data exporting. • #Debian Linux as a main engine. 💡 Takeaway: Zero proprietary software licenses needed. Complete reproducibility from raw analytical data to a print-ready PDF. 🔗 The published version of monoghraph is here: https://zenodo.org/records/20709306 #Hydrogeology #Geochemistry #LaTeX #GIS #OpenScience #DataScience #SvystunovaGully
