Natural cave passages penetrating a coastal aquifer in the Yucatan Peninsula (Mexico) were accessed to test the hypothesis that chemoclines associated with salinity gradients (haloclines) within the flooded cave networks of the karst subterranean estuary are sites of methane oxidation. Two field trips were carried out to the fully-submerged cave system located 6.6 km inland from the coastline in January 2015 and January 2016. Vertical chemical profiles across the water column haloclines were obtained using the OctoPiPi (OPP), a high-resolution water sampler built by the U.S. Geological Survey (USGS). The sampling efforts resulted in cm-scale profiles of major ions (e.g., chloride and sulfate), as well as concentrations...

Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers that contain a surprising diversity of endemic animals (mostly crustaceans) within a highly oligotrophic environment. How complex ecosystems thrive in this globally-distributed, cryptic habitat (termed anchialine) is poorly understood. The northeastern margin of the Yucatan Peninsula contains over 250 km of mapped, diver-accessible caves passages where previous studies have suggested chemoautotrophic processes are the source of carbon and energy sustaining the anchialine food web.

This dataset includes single point airflow monitoring data collected with an ultrasonic anemometer (velocity and direction) recorded at five selected locations in a commercial cave in Greene County, Missouri. The data was collected as part of a larger effort to monitor air contamination in commercial caves by the Missouri Department of Natural Resources.

The nature of carbon (C) cycling in the vadose zone where groundwater is in contact with abundant gas-filled voids is poorly understood. The objective of this study was to trace C cycling in a karst landscape using stable-C isotopes, with emphasis on a shallow groundwater flow path through the soil, to an underlying cave, and to the spring outlet of a cave stream in the Ozark Plateaus of northwestern Arkansas. Blowing Spring Cave (BSC) occurs in the Springfield Plateau of the Ozark Plateaus. The cave passage is relatively horizontal, the entrance to BSC is a spring outlet, and no other human-sized entrances into the cave are known to occur. Soils generally are less than 2 to 3 meters thick above the cave and dominated...

This dataset includes airflow monitoring data using an ultrasonic anemometer (velocity and direction), manual check measurements at three locations in the borehole using a handheld hotwire anemometer, and temperature data recorded adjacent to a 22 inch borehole at a commercial cave in Greene County, Missouri. The borehole was drilled to supplement primary ventilation for the cave, and this data documents the airflow into and out of the borehole, as well as the temperature of outside air. This data was collected as part of a larger effort to monitor air quality in Missouri commercial caves by the Missouri Department of Natural Resources.

These datasets are products of Phase II of the Appalachian Landscape Conservation Cooperative’s (LCC) landscape conservation design (LCD) created by Clemson University as part of the LCC-funded project, “Interactive Conservation Planning for the Appalachian LCC”. The Appalachian NatureScape Design incorporates and models newly developed data and information from all Appalachian LCC funded research projects as well as key existing datasets from partners to produce a series of maps that integrate aquatic connectivity with terrestrial significant habitats to guide conservation planning and decision making.Conservation Planning, a process of spatially identifying and prioritizing lands and waters important for functioning...

Natural cave passages penetrating a coastal aquifer in the Yucatan Peninsula (Mexico) were accessed to investigate how regional meteorology and hydrology control methane dynamics in karst subterranean estuaries. Three field trips were carried out in January 2015, June 2015, and January 2016 to obtain year-long high-resolution temporal records of water chemistry and environmental parameters below and above the surface at a site (Cenote Bang) within the Ox Bel Ha cave network. These efforts resulted in chemical records of dissolved methane concentrations and its stable carbon isotopic content and major ion concentrations (i.e., chloride and sulfate) in approximately 2.5-day resolution from January 2015 to January...

In 2019, dye tracing investigations were conducted near Manitou Cave in Dekalb County, northeast Alabama. The purpose of the dye tracing was to delineate a recharge area for the stream in Manitou Cave, a 1.7-kilometer-long stream cave and the only known habitat for the Manitou Cavesnail (Antroribus breweri). In 2010, the U.S. Fish and Wildlife Service was petitioned by the Center for Biological Diversity to federally list the Manitou Cavesnail. However, before any listing or vulnerability designation can occur, more knowledge was required, specifically regarding potential threats to the snail. With regards to the Manitou Cavesnail, this required delineating a recharge for the stream in Manitou Cave in order to determine...

Percent of each freshwater ecoregion’s area containing karst terrain. We derived the percentage area of ecoregions that may contain karst from the global karst data set by Williams and Ford (2006). The global karst data set was an update of a previous version from Williams and Ford that was released in 2005 by Carbon, Hydrology, and Global Environmental Systems (CHANGES), a collaboration of the International Geoscience Programme (IGCP) and sponsored by the UN Educational, Scientific and Cultural Organization (UNESCO) and the International Union of Geological Sciences. We summarized the global karst polygons by calculating the percentage area of ecoregions covered by karst. Total karst area generally reflects the...

This dataset includes airflow monitoring data (velocity and direction) and temperature data recorded at several locations in a commercial cave in Greene County, Missouri. These data were collected as part of a larger effort by the Missouri Department of Natural Resources to monitor air quality in Missouri commercial caves. The data set includes single-point airflow measurements using an ultrasonic anemometer at five locations within the cave. Airflow measurements using an ultrasonic anemometer and manual check measurements using a handheld hotwire anemometer also were made in a 22-inch diameter vent shaft upcave (further from the entrance) of the commercial tour route. In addition, outside air temperature also was...
