Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from public sources: plongeesout.ffspeleo.fr (FFS site sheets, mostly 1994–2007; Dhuit 2019), the GERSM and CDS 55, Wikipedia, grottomap (IKARE data), showcaves.com, Spéléo Club de Paris, ABIMES, the Maison lorraine de la spéléologie, the FFS, the Meuse département, JHM, Haute-Marne Attractivité, fontesdart.org, MedSubHyp and CDS 07 (September 2026). Much of the dive data is old or comes from a single exploration team. Pins from Wikipedia and grottomap or converted from plongeesout's Lambert coordinates; the Dhuit has no pin yet. ~ = estimate.
