“…Research underwater cave and sinkhole sediment has significantly expanded in the last several decades from the realization that these deposits can preserve records of paleoceanography (Yamamoto et al, 2010;van Hengstum et al, 2015a), tropical cyclone variability (Lane et al, 2011;Brandon et al, 2013;Denomee et al, 2014;van Hengstum et al, 2014), long-term groundwater conditions and salinity (Teeter and Quick, 1990;Teeter, 1995;Alverez Zarikian et al, 2005;Gabriel, 2009;van Hengstum et al, 2010;Quillen et al, 2013), millennial-scale terrestrial-oceanic climatic connectivity (Grimm et al, 1993), glacial-interglacial climate oscillations (Larsen and Mangerud, 1989), vertical sea-level and water-level change (van Hengstum et al, 2011;Collins et al, 2015a), and precipitation variability (Wurster et al, 2008;Polk et al, 2013;Onac et al, 2015). However, many questions still surround their millennial scale sedimentary processes because few flooded caves have received detailed sedimentary reconstructions.…”
