“…Our range of calculated denudation rates (95% CI for BICY as a whole: 0.004-0.025 mm yr −1 through the Ca method and 0.008-0.037 mm yr −1 through the Joint method) are lower than many other karst denudation studies have found (Florea, 2015). Big Cypress denudation rates are only 10% of those determined in the Jura Mountains and many karst streams in the US, and they are only 1% of those determined in the Akiyoshi-dai Plateau in Japan (Akiyama et al, 2015;Calmels et al, 2014;Covington et al, 2015). Both the Jura mountains and Akiyoshi-dai Plateau have steep slopes -a condition in which mechanical erosion is likely to contribute to denudation, and in which faster flowing water will have less of a transportation barrier to dissolution (Ryb et al, 2014;Sweeting, 1973).…”

“…Karst landscapes, due to the highly soluble nature of their rock, export their weathering products hydrologically, creating a wide variety of features such as caves, karst towers, and dissolution holes, but also causing natural hazards such as sink holes (Ford and Williams, 2007). Preferential flow paths through the landscape attract disproportionately large volumes of water, and this water, which is undersaturated with respect to carbonate, dissolves the rock along the conduit walls and creates a positive feedback loop of dissolution and flow (Akiyama et al, 2015;Perne et al, 2014;Sweeting, 1973). These conduits are classically subsurface (e.g.…”

Mass balance implies Holocene development of a low-relief karst patterned landscape

et al. 2019

We constructed mass balances of both calcium and phosphorus for two watersheds in Big Cypress National Preserve in southwest Florida (USA) to evaluate the time scales over which its striking landscape pattern developed. This low-relief carbonate landscape is dotted with evenly spaced, evenly sized, shallow surface depressions that annually fill with surface water and thus support wetland ecosystems (e.g. cypress domes) embedded in a pine-dominated upland matrix with exposed bedrock. Local and landscape scale feedbacks between hydrology, ecological dynamics and limestone dissolution are hypothesized to explain this karst dissolution patterning. This hypothesis requires the region to be wet enough to initiate surface water storage, which constrains landscape formation to interglacial periods. The time scale therefore would be relatively recent if creation of the observed pattern occurred in the current interglacial period (i.e. Holocene), and older time scales could reflect inherited patterns from previous inter-glacial periods, or from other processes of abiotic karstification. We determined phosphorus stocks across four landscape compartments and estimated the limestone void space (i.e., wetland depression volume) across the landscape to represent cumulative calcium export. We calculated fluxes in (e.g., atmospheric deposition) and out (i.e., solute export) of the landscape to determine landscape denudation rates through mass balance. Comparing stocks and annual fluxes yielded independent estimates of landscape age from the calcium and phosphorus budgets. Our mass balance results indicate that the landscape began to develop in the early-mid Holocene (12,000-5000 ybp). Radiocarbon dating estimates implied similar rates of dissolution (~1 m per 3000-3500 years), and were in agreement with Holocene origin. This supports the hypothesis that ecohydrologic feedbacks between hydrology and vegetation occurring during the present interglacial period are sufficient to shape this landscape into the patterns we see today, and more broadly suggests the potential importance of biota in the development of macro-scale karst features.

This study aims to clarify the solution characteristics of carbonate rock tablets in a tropical savannah climate. The study site is located within the ruins of the Angkor Wat Temple in north western Cambodia. Two kinds of carbonate rock from Japan were used: middle Carboniferous limestone from the Akiyoshi-dai Plateau and marble from the Abukuma Mountains. The tablets used in the experiment were fashioned into discs 40 mm in diameter and 4 mm in thickness. They were then placed horizontally in a secure rack 120 cm above the ground, next to a weather station, and remained exposed from August 24, 2011 to March 15, 2014 (a duration of 934 days) . The tablets were weighed before, during, and after the experiment in order to measure changes due to dissolution effects. The initial weights of the tablets were 13.624 g for limestone and 13.700 g for marble; on day 934, their dry weights were 13.523 g for limestone (99.26％ of initial weight) and 13.630 g for marble (99.49％ of initial weight) . The experiment produced three major results: (1) limestone dissolves faster than marble; (2) solution occurred most rapidly during the initial test period, and thereafter progressed constantly but at a lower rate; (3) the observed solution rate under a tropical savannah climate was lower than previously reported values from a humid temperate climate derived from equivalent methods. The faster solution of limestone is thought to occur because limestone has a higher composition of fine-grained calcite than marble; therefore, it has a larger surface area, which is more conducive to solution reactions. In tandem with surface solution of post-test tablets, calcite surfaces are covered with recrystallized products, such as speleothems. Thus, under a tropical savannah climate with a clearly defined dry season, recrystallization associated with moisture loss is likely to reduce the solution rate. For solution processes to progress most effectively within carbonate rock, appropriate temperature conditions are not sufficient; continuous contact with water is also essential.
