In the tropical Atlantic region, 18O values of precipitation are generally linked to summer rainfall amount, a relationship which is based on the type and source of wet season (convective) versus drier season (orographic) rainfall28,29,30. Cenote Zapote - Hells Bells near Playa del Carmen - Koox Diving Earth Surf. Chen, T. et al. The cenote is bottle-shaped in cross section with a central debris mound (Fig. S2). Geol. Verification of recent growth of Hells Bells is challenging considering the low growth rates and the partly high concentrations of 232Th (up to 6ngg1) in Tree Bell samples. From 7.7 to 2.5 ky BP, i.e., from 3.7 to 53.5cm dfa, the ages of ZPT-7 suggest more regular growth with an average growth rate of about 100myear1 (Fig. Sect. Rev.

There is a line laid out around the debris cone and fallen trees at the very base. Small Group Day Tour, Private Underwater Photoshoot Isotopically enriched U is supplied through diffusion from the underlying saline groundwater body, even if the concentration of uranium is reduced here due to anoxic conditions in which U behaves particle reactive. Currently the bells continue their growth in the water. 230Th/U-dating of the antapical ends of Tree Bells collected from water depths between 32.7 and 37.3m yielded ages between 0.170.13 and0.0260.021ky BP (Supplementary Fig. There are some car parking spots, bathrooms and toilets, open-air showers and two platforms for jump-diving into the cenote. 115138 (Food Products Press, 2003).

The trend in the isotope correlation is also visible through time, with decreasing 13C values and increasing 18O values towards younger ages (Figs. We therefore focus on the discussion of the significant findings of the mid- to late Holocene samples in the following. It is located on the Ruta de los Cenotes" the old road from Puerto Morelos to Valladolid. Surrounding the cenote, Zapote Eco-park is well worth taking the time to explore. Kerber, I. K. et al.

Cenote Zapote ("Hells Bells"), Mexiko (4K/UHD) - YouTube An alternative hypothesis on the formation of Hells Bells speleothems in cenote El Zapote was suggested by Lpez-Martnez et al.4, who proposed that Hells Bells represent folia speleothems that form as a result of subaqueous calcite precipitation around CO2 bubbles trapped below overhanging walls of the cave4. https://doi.org/10.2475/04.2014.01 (2014).

Water samples between 0 and 36m were retrieved using a 0.5m high Polyethylene FreeFlow bottle (HYDRO-BIOS, Kiel, Germany), and samples between 36 and 52m were collected by technical divers by drawing up the water of the desired sampling depth into sterile PE-luer-lock syringes (140mL) with an attached three-way valve25.

This research was funded by the Deutsche Forschungsgemeinschaft (grants STI128/28, STI128/36, KE 884/8-2, SCHO 1274 11-1 and DFG 247825108), and the CONACYT-FONCICYT-DADC (grant no. 6, 257274.

Sometimes you can see the actual line where they meet and thats cool too. A beautiful little cenote just outside of Puerto Morelos. Diving Cenote Zapote "Hells Bells" - Mexiko 2022 - YouTube These authigenic calcite precipitates, reaching a length of up to 4m, most likely grow in the pelagic redoxcline. Our goal is to give our divers a personalized service and the opportunity to choose the cenote dive they want to do. Kovacs, S. E. et al. The middle parts of the day give the sun the best chance of shining down to deeper depths and producing a more impressive light show, however! https://doi.org/10.1016/j.epsl.2013.04.006 (2013). Sci. Known as Hell's Bells, these strange stalactites can measure up to two meters in height, and are immersed at a depth ranging from 28 to 33 meters. Overall, the results of the 230Th/U-dating on different Hells Bells specimens from different cenotes on the YP thus reveal at least semi-continuous growth of Hells Bells since about 8.5 ky BP until present. Youll notice that most of my videos have a green tint. Based on these findings, changes in 18O values of Hells Bells calcite most likely represent long-term changes of local precipitation amount and/or convective activity. Uranium concentrations are anticorrelated with 234U values (rU/234U=0.68, p<0.05). 14, 3847. Coral Reef, Puerto Aventuras Kovacs, S. E. et al. 2 Dives for Advanced Divers, Whale Shark Snorkel Tour The cenote gains its official name from the Zapote trees which grow around the vibrant jungle entrance. Large bellshaped calcite formations called "Hells Bells" were discovered underwater in the stratified cenote El Zapote on the Yucatn Peninsula, Mexico. Diving is cenote div.

Here, 13C values correlate inversely with 18O values (r13/ 18O=0.7, p<0.05). Cenote Zapote/ Hells Bells | Pro Dive International Google Scholar. Most Hells Bells samples reveal 13C values ranging from14 in cenote El Zapote, to11 in cenote Tortugas (Figs.

Similar to the study of van Hengstum et al.34, Sr/Ca and Cl/Ca ratios of calcite raft deposits in cenotes Ich Balam and Hoyo Negro (Fig. Cenote diving in Zapote is an incredible experience. Cenote Tortugas (205111.7N 870630.1W) is located 24km west of Puerto Morelos coast and about 2km east of cenote El Zapote. Coutino, A., Stastna, M., Kovacs, S. & Reinhardt, E. Hurricanes Ingrid and Manuel (2013) and their impact on the salinity of the Meteoric Water Mass, Quintana Roo, Mexico. Further, we do not know whether the Fe-sulfide layers within the roots of Big Bell and ZPT-7or the processes that led to their formationmay have had an influence on the geochemistry of the adjacent calcite layers and thus the 230Th/U ages.

During most of the last 8.5 ky, 230Th/U-dating provides clear evidence for partly continuous growth of Hells Bells, for example, from 7.5 to 2.5 ky BP in ZPT-7 (Fig. Article De Waele, J. et al. Zapote (Hells Bells) | Cenoten Tauchen in Mexiko - YouTube TL4 from the turbid layer in cenote El Zapote at 35.8m water depth or MIII from cenote Maravilla at 29.4m water depth), samples collected from the bottom of cenote El Zapote (e.g. MUSA Cancun & Whale Sharks, Wildlife Safari 238U,234U and232Th in seawater. The caves were originally above ground when they formed and so some are incredibly decorated with stalactites, stalagmites, columns and all the beautiful speleothems (a structure formed in a cave by the deposition of minerals from water) youd expect to find in a cave. Dive 8 of 8 Cenote Dives. Subaqueous speleothems (Hells Bells) formed by the interplay of pelagic redoxcline biogeochemistry and specific hydraulic conditions in the El Zapote sinkhole, Yucatan Peninsula, Mexico. Samples<8.5 ky BP are color-coded depending on their respective age. Let me play among the stars Cosmochim. Reconstructions of mid- to late Holocene relative sea-level rise in Mexico show that sea level increased by roughly 810m during the last~8 ky (Fig. #passion White Vol. 497, 157167.

Furthermore, we constrain the subaquatic growth of the Hells Bells and discuss the specific physical and biogeochemical conditions of their formation.

The molar ratio of Mg/Ca (2.45.1102) appears rather constant through time (Fig. In the past I used a 24mm lens and it was wonderful for the detail of the decorations, but you didnt get the feeling of drifting down into the tunnels, between rocks and so much more you experience in the caverns. However, the large spatial extent of systematic geochemical changes of the freshwater lens and calcite chemistry is well expressed by Hells Bells samples from the cenotes El Zapote, Maravilla and Tortugas, which, like the calcite rafts from cenotes Ich Balam and Hoyo Negro38, show consistently decreasing Sr/Ca ratios and thus a decrease in the salinity of the freshwater lens during the last~8 ky (Fig. Drivers of Holocene sea-level change in the Caribbean. Ritter, S. M. Unravelling the Formation of Hells Bells: Underwater Speleothems From the Yucatn Peninsula in Mexico Ph.D. thesis, Heidelberg University (2020). I used a super wide-angle lens on this trip that was so wide, even my new BigBlue, 160 degree, 15,000 lumen video light couldnt fully cover the view. The red curves are a 3rd order polynomial fit through Hells Bells Sr/Ca ratios and 234U0 values, respectively. Aliquots of all samples were taken for the subsequent geochemical analyses. Geochim. Good and fresh lunchs/snacks. Initial 234U0 values vary from 15.11.2 to 62.64.6, with the highest values observed in the early Holocene and systematically decreasing values for the mid- to late Holocene (see Table S1).

Science 354, 550551. Simultaneous U and Th isotope measurements for U-series dating using MCICPMS. Local cave divers discovered these unusual speleothems and named them Hells Bells because of their bell-like shape and their occurrence in a lightless environment at great water depths close to a sulfidic and turbid halocline, separating the seawater from the overlying freshwater lens.
