Description:
Abstract:
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 2016, sampled by OsmoSamplers. In addition, sensor-based measurements of environmental parameters include year-long precipitation, barometric pressure, water level, flow velocity, and water temperature records. 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 investigate how regional meteorology and hydrology control carbon cycling and methane dynamics in the karst subterranean estuary.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal position (coordinates) of the entrance pool of Cenote Bang was obtained with a Garmin GPSmap 60CSx GPS, which has a positional accuracy of less than 10 meters. Coordinates for the locations where the individual 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.

Process_Description:
The year-long records were obtained during two deployment periods at two locations. The first deployment was from January-15-2015 to June-15-2015 and the second deployment was from June-15-2015 to January-23-2016. Meteorological parameters (i.e., precipitation, barometric pressure and air temperature) were acquired at a meteorological station installed on the roof of Speleotech facility, located approximately 3.5 km from the Cenote Bang cave entrance. OsmoSamplers (to obtain chemical records) and data-loggers (to monitor water level, flow, water temperature) were deployed in the cave environment accessed through Cenote Bang by scuba divers who followed protocols established by the American Academy of Underwater Sciences and the National Speleological Society Cave Diving Section.
Full details related to the processing of the samples, storage, analysis, and attribute accuracy are provided in the Methods section of Brankovits and others, 2018. Processing took place after each deployment period in 2015 and 2016.

Process_Step:
Process_Description:
I. Passive measurements made at the meteorological station using sensor-based data loggers:
Precipitation was measured with a rain gauge (Onset RG-3, calibration accuracy of ± 1.0%, up to 2 centimeter per hour (cm h−1); 0.2 mm resolution; time accuracy ± 1 minute per month) and is presented as daily total precipitation in millimeter per day (mm d−1). For resulting data, see data sheet 'precipitation' in data file 'CenoteBangTemporalRecords_2015-2016.xlsx'.
Barometric pressure was monitored at 15-min time intervals alongside the rain gauge with an Onset U20 data logger (less than 0.02 kPa resolution and a ± 0.3% FS or 0.62 kPa accuracy as the maximum error) that also measured air temperature (0.1 degC resolution, ± 0.44 degC accuracy). For resulting data, see data sheet 'barometer' in data file 'CenoteBangTemporalRecords_2015-2016.xlsx'.
II. Passive measurements within the flooded cave environment using sensor-based data loggers:
Within the cave, groundwater flow velocity, water level, and water temperature were monitored at 17 m water depth in the brackish water (BW) and at 22 m water depth in the saline groundwater (SG). Velocity was measured as current speed and direction with a TCM-1 (Lowell Instruments, LLC) tilt current meter (TCM; ± 2 centimeter per second (cm s−1) ± 3% of reading accuracy and 0.1 centimeter per second (cm s−1) resolution; bearing ± 5 degree accuracy for speed greater than 5 centimeter per second (cm s−1) with a 0.1 degree resolution) at 1-minute intervals. For resulting data, see data sheets 'flow_BW' and 'flow_SG' in data file 'CenoteBangTemporalRecords_2015-2016.xlsx'.
Water level, measured with an Onset U20 logger (± 0.21 cm with an error less than ± 1.0 cm at 15-min intervals), is reported as absolute depth and departure from the mean value after compensating for barometric pressure changes measured at the meteorological station. This logger also measured water temperature (0.1 degC resolution, ± 0.44 degC accuracy). For resulting data, see data sheets 'water_level_BW' and 'water_level_SG' in data file 'CenoteBangTemporalRecords_2015-2016.xlsx'.
III. Chemical analyses of water samples collected with the OsmoSamplers in the cave environment:
Analysis of the samples was performed at the Woods Hole Oceanographic Institution (WHOI) and U.S. Geological Survey (USGS) in Woods Hole MA, USA. Sulfate and chloride concentrations were determined using a Metrohm 881 Compact Plus ion chromatograph (IC) equipped with a Metrosep A Supp 5-250 anion column. Chloride concentrations in millimolar (mM) were converted to milligrams per liter (mg l-1) and multiplied by 0.0018066 to determine salinity (psu - practical salinity unit). The analytical error for chloride and sulfate was +/- 3.5% of the IAPSO (International Association for the Physical Sciences of the Oceans) standard sulfate and chloride values.
Headspace methane concentrations were determined using a Shimadzu GC-14-B gas chromatograph (GC) equipped with a flame ionization detector (FID). Headspace concentrations were converted to dissolved concentrations using the method of Magen and others, 2014 and are reported with an relative standard deviation of 2%.
The stable carbon isotope composition of methane from the headspace of the serum vials was determined using a Thermo-Finnigan DELTAPlus XL isotope ratio mass spectrometer (IRMS) coupled to an Agilent 6890 Gas Chromatograph (GC) via a Finnigan GCCIII combustion interface with 1-sigma deviation of 1.6 per mil.
For resulting data, see data sheets 'osmosampler_FW' and 'osmosampler_BW' in data file 'CenoteBangTemporalRecords_2015-2016.xlsx'.
Full details related to the processing of the samples, storage, analysis, and attribute accuracy are provided in the Methods section of Brankovits and others, 2018. Processing took place after each deployment period in 2015 and 2016.

Entity_and_Attribute_Overview:
These data are available in a XLSX and CSV format. The Excel spreadsheet has 8 individual sheets, each containing data obtained with an individual logger or sampler. The entity type label is the same as the Excel sheet label and the CSV filename. The first row of the Excel spreadsheet contains a header line that includes the type of record (i.e., chemical record, sensor-based data record from meteorological station, sensor-based data record from groundwater), a general description of the study, and the years the data were obtained; the second row indicates the type of logger or sampler utilized and, for cave deployments, includes information regarding the deployment depth and specific water layer sampled; the third row corresponds to the attribute label described above (and may contain special characters), and the fourth row of the Excel sheet corresponds to the first row of the CSV file (which has a simplified column heading). The CSV column headers are also the first part of the attribute definition in the detailed entity and attribute section. Each Excel sheet corresponds to a CSV file as described below:
Sheet barometer corresponds to file barometer.csv;
Sheet precipitation corresponds to file precipitation.csv;
Sheet water_level_BW corresponds file water_level_BW.csv;
Sheet water_level_SG corresponds to file water_level_SG.csv;
Sheet flow_BW corresponds to file flow_BW.csv;
Sheet flow_SG corresponds to file flow_SG.csv;
Sheet osmosampler_FW corresponds to file osmosampler_FW.csv;
Sheet osmosampler_BW corresponds to file osmosampler_BW.csv.
