“…This increase in salinity and water depth marked the demise of the marsh, and the pollen rain became dominated by plant species (such as Buxus glomerata ) growing outside the cenote basin (Figure ). This same process is recorded at Cenote Aktun Ha, on the Caribbean coast of Mexico, with RSL‐driven water level increase drowning a mangrove community, forming the modern‐day cenote [ Gabriel et al ., ], and also more broadly at other cenotes and cave deposits in the Yucatan [ Collins et al ., ; Collins et al ., ].…”

We use sediments from a flooded sinkhole (Cenote Jennifer) in northern Cuba to provide new, well‐dated, high‐resolution evidence for the 8.2 kyr event. From ~7600 to 8700 cal yr B.P. the sinkhole contained shallow, low‐salinity water, which supported a marsh dominated by cattail and grass. Peaks in Cl and Br—occurring at 8150, 8200, and 8250 cal yr B.P.—are attributable to increased evaporation due to regional drying associated with the 8.2 kyr event. The three peaks in these elements also closely correspond to the greyscale record from the Cariaco Basin, indicative of increased upwelling in the southern Caribbean Sea at this time, supporting the notion of a multistage 8.2 kyr event. Our work provides new data that help to clarify the initiation, behavior, and impacts of the 8.2 kyr event in the northern tropics.

“…Inundation by base level due to sea-level rise controls many cave sedimentary processes, and it changes the sedimentary structures that may be generated or preserved in the stratigraphic record. As such, sedimentary deposits and structures (both primary and secondary) can be associated with phreatic versus vadose environmental conditions in the cave S ringer and ite S ringer et al van engstum et al van Hengstum et al, 2015b) or conduit geometry (Collins et al, 2015a).For example, a submarine cave at 210 m BSL on Johnston Island (Central Pacific) contains no sediment (Keating, 1985), and sedimentation in some Mexican (Yucatan) phreatic caves was initiated by emplacement of mangroves on the epikarst surface (Collins et al, 2015b) The spatial position of the cave system relative to the ocean can further complicate sedimentary interpretations. This is because the position of the water table in the coastal zone is linked to eustatic sea-level change (Gascoyne et al, 1979;Shinn et al, 1996;van Hengstum et al, 2011), whereas the water table is impacted by other variables further inland (e.g., structural geology, lithology, hydrogeologic gradients).…”

Detrital sediment in Florida's (USA) submerged cave systems may preserve records of regional climate and hydrologic variability. However, the basic sedimentology, mineralogy, stratigraphic variability and emplacement history of the successions in Florida's submerged caves remains poorly understood. Here we present stratigraphic, mineralogical, and elemental data on sediment cores from two phreatic cave systems in northwestern, Florida (USA), on the Dougherty Karst Plain: Hole in the Wall Cave (HITW) and Twin Cave. Water flowing through these cave represents subsurface flow in the Apalachicola River drainage basin, and the caves are located just downstream from Jackson Blue (1 st magnitude spring, >2.8 m 3 s −1 discharge). Sedimentation in these caves is dominated by three primary sedimentary styles: (i) ferromanganese deposits dominate the basal recovered stratigraphy, which pass into (ii) poorlysorted carbonate sediment, and finally into (iii) fine-grained organic matter (gyttja) deposits upsection. Resolving the emplacement history of the lower stratigraphic units was hampered by a lack of suitable material for radiocarbon dating, but the upper organic-rich deposits have a punctuated depositional history beginning in the earliest Holocene. For example, gyttja primarily accumulated in HITW and Twin Caves from ~5500 to 3500 cal yrs BP, which coincides with regional evidence for water-table rise of the Upper Floridian Aquifer associated with relative sea-level rise in the Gulf of Mexico, and evidence for invigorated drainage through the Apalachicola River drainage basin. Gyttja sediments were also deposited in one of the caves during the Bølling / Allerød climate oscillation. Biologically, these results indicate that some Floridian aquatic cave (stygobitic) ecosystems have been significantly devoid of recent organic matter supply in comparison to prehistoric intervals.

“…Some prominent examples of blue holes with anoxic bottom waters are the Great Blue Hole, Belize (Gischler et al, ), South Andros Black Hole, Bahamas (Schwabe & Herbert, ), blue holes in the Great Barrier Reef of Australia (Backshall et al, ), and the Clipperton Atoll blue hole, Île de Clipperto (Sachet, ). Blue holes can also preserve scientifically significant sedimentary archives of environmental change and hurricanes (e.g., Gischler et al, ; Tamalavage et al, ; Collins et al, ; Brown et al, ; van Hengstum et al, , , , ; Wallace et al, ) and may serve as natural laboratories for studying extreme chemicophysical gradients in aquatic ecosystems.…”

Carbon Cycling in the World's Deepest Blue Hole

Blue holes are unique geomorphological features with steep biogeochemical gradients and distinctive microbial communities. Carbon cycling in blue holes, however, remains poorly understood. Here we describe potential mechanisms of dissolved carbon cycling in the world's deepest blue hole, the Yongle Blue Hole (YBH), which was recently discovered in the South China Sea. In the YBH, we found some of the lowest concentrations (e.g., 22 μM) and oldest ages (e.g., 6,810 years before present) of dissolved organic carbon, as well as the highest concentrations (e.g., 3,090 μM) and the oldest ages (e.g., 8,270 years before present) of dissolved inorganic carbon observed in oceanic waters. Sharp gradients of dissolved oxygen, H2S, and CH4 and changes in bacterially mediated sulfur cycling with depth indicated that sulfur‐ and/or methane‐based metabolisms are closely linked to carbon cycling in the YBH. Our results showed that the YBH is a unique and easily accessible natural laboratory for examining carbon cycling in anoxic systems, which has potential for understanding carbon dynamics in both paleo and modern oceans—particularly in the context of global change.
