摘要: Abstract Coastal karst aquifers have an upper meteoric water mass stratified from a saline groundwater below that increasingly mix and discharge towards the ocean. Preserved sediment in caves sinkholes provide opportunity to evaluate long-term hydrodynamics local coastal aquifer (e.g., salinity, oxygenation, vertical displacement response sea-level forcing). Here we of shallow ( 45 μm versus >63 μm mesh sieve fractions. These modern analog results can be used interpret subfossil benthic foraminiferal records aquifers, especially during early cave inundation by concomitant rise.
