Three field trips were carried out in December 2013, August 2014, and January 2015 to obtain 1) physicochemical and 2) geochemical data from the water column and 3) temporal records of water chemistry and hydrological parameters below and above the surface at three sites within the Ox Bel Ha cave (Cenote Jailhouse, Cenote Naach Wennen Ha, and Cenote Odyssey) and another cave (Cenote Crustacea). These efforts resulted in vertical physicochemical and geochemical profiles from the water column of the flooded caves from the region. In addition, the sampling resulted in temporal chemical and hydrological records of dissolved methane concentrations and chloride concentrations (used to calculate salinity) from August 2014 to January 2015, sampled by OsmoSamplers. The records encompass wet and dry seasons and include the impact of Tropical Storm Hanna during October 2014. Field activities were carried out by the U.S. Geological Survey (USGS) Coastal and Marine Geology Program in conjunction with Texas AM University at Galveston. Purpose: These data are used to characterize the habitat and constrain the biogeochemical processes that support anchialine habitat ecosystems. The sonde data are used to identify details about the physical and chemical structure of the water column and availability of dissolved oxygen in the subterranean estuary.

Online_Linkage: https://doi.org/10.1002/LNO.12231 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The accuracy of each attribute is determined by a sensor specific to that attribute, which is provided in the process step for each measurement Logical_Consistency_Report: Data from the various sondes were processed in the same manner by the same individual (David Brankovits under the supervision of john Pohlman). Although two different sondes were used to collect the data they utilized the same sensors with similar accuracies (reported below) and were calibrated in the same way to insure cross-sensor agreement. Completeness_Report: All data collected are represented here. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizonal position (coordinates) of the entrance pools of the cave locations (Cenote Crustacea, Cenote Jailhouse, Cenote Odyssey, and Cenote Naach Wennen Ha) were obtained with a Garmin GPSmap 60CSx GPS, which has a positional accuracy of less than 10 meters. Coordinates for the sampling stations where the individual water profiles were collected are not available because the GPS does not operate in overhead or underwater settings. The bounding coordinates provided in this data release incorporate the horizontal extent of the passages investigated in this study. However, as stated previously, the precise locations of the passages are unknown. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The accuracies of the vertical (depth) measurements are +/-0.12 m for the 600XLM and +/-0.10 m EXO2. Lineage: Process_Step: Process_Description: The YSI EXO1 sonde (used in Dec 2013) and the YSI 600-XLM sonde (used in Aug 2014 and Jan 2015) were both calibrated according to manufacturer specifications. Sonde profiles were measured along vertical depth profiles in the water column of the caves and cenotes (entrance pools) with a measurement frequency of 0.25 – 2 Hertz (Hz). The sonde was carried by the lead diver, slowly descending (2-4 centimeter per second [cm/s]) and advancing with the probes projecting forward to ensure an undisturbed profile of the water column. Data was downloaded using KOR software by David Brankovits (supervised by John Pohlman) and processed within Microsoft Excel.
