Cursos de Patrimonio Cultural Subacuático

Cristalsub offers a set of cultural and natural heritage modules that sit outside the standard certification ladder. The five areas covered are: conservation of underwater cultural heritage, underwater cultural and archaeological heritage (methodology, site types, restoration basics), cultural and natural heritage in inland continental waters, subaquatic geological heritage (marine geology, submarine relief, depositional environments), and natural subaquatic heritage (fauna and marine environments around Spanish territory).

These aren't recreational specialties designed to add a card to your logbook — they're content-focused courses aimed at divers who want to understand the context of what they're diving through. The inland waters module is particularly specific: it covers diving in lakes and reservoirs legally, safely, and sustainably, which is a niche area that few clubs address directly.

Contact the club for scheduling and prerequisites. These modules appear to run periodically rather than on a fixed calendar.
