Water level oscillations in coastal caves: relationships with sea level variations and POS development (Coves del Drac, Mallorca, Western Mediterranean

Key Points

• The aim is to understand how water level changes in coastal caves relate to external sea level variations and the development of Paragenetic Origin Structures (POS).
• Analyzed water level changes in cave pools of Coves del Drac.
• Examined relationships between cave tides and external coastal tidal influences.
• Assessed POS growth in alignment with modern sea level oscillations.
• Water level changes in cave pools are significantly influenced by coastal tides.
• Current POS growth corresponds to recent sea level variations.
• POS serve as indicators of historical and present sea levels in coastal caves.
