Description:
Abstract:
Natural cave passages penetrating coastal aquifers in the Yucatan Peninsula (Quintana Roo, Mexico) were accessed to investigate how regional meteorology and hydrology control dissolved organic carbon and methane dynamics in karst subterranean estuaries, the region of aquifers where fresh and saline waters mix. 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 ecosystems. The geochemical data are used to identify details about the carbon cycle in the subterranean estuary.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of each attribute is determined by that analysis specific to that attribute, and is provided in the process step for each measurement
Logical_Consistency_Report:
All data provided in this release were obtained by PhD student David Brankovits under the supervision of USGS Research Geochemist John Pohlman. Although samples were collected over several years during differet sampling campaigns, the collection, processing, and analyses of samples followed the same protocols in a consistent manner.
Completeness_Report:
For missing values, the sample was either not collected, lost in shipping or has not been analyzed. The condition of the missing values (e.g., not collected, lost in shipping or not analyzed), is not specified. Apparent gaps in numbers are a result of different mode of sample collection (thus, those samples are not included in this data release) OR lost samples.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizonal position (coordinates) of the entrance pool of the caves (Cenote Crustacea, Cenote Jailhouse, Cenote Odyssey, and Cenote Naach Wennen Ha) was obtained with a Garmin GPSmap 60CSx GPS, which has a positional accuracy of less than 10 meters. Coordinates for the sampling stations within the caves where the samples were collected from 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 approximate depth associated with each sample was obtained from the collecting divers depth gauge, which is accurate to +/-0.3 m.

Process_Step:
Process_Description:
Discrete water samples were collected from Ox bel Ha cave (Cenote Jailhouse, Cenote Odyssey, and Cenote Naach Wennen Ha) and another cave (Cenote Crustacea) during three sampling events: December 2013, August 2014, and January 2015. Cenote and cave samples were collected by scuba divers following protocols established by the American Academy of Underwater Sciences and the National Speleological Society Cave Diving Section. Water samples for geochemical analysis of dissolved materials were collected near sonde profile locations in plastic 60 ml syringes fitted with 3-way stopcocks. The syringes were rinsed with distilled water and dried prior to the dive, and flushed with sample water prior to closing the stopcock. Samples were kept cool during transport to the field lab and preserved within eight hours of collection. More details related to the processing of the samples after collection are provided in the Methods section of Brankovits and others, 2017.

Process_Step:
Process_Description:
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 milliMolar (mM) were converted to milligrams per liter (mg l-1) and multiplied by 0.0018066 to determine salinity (psu). The analytical error for chloride and sulfate was +/-3.5 percent (%) of the IAPSO standard sulfate and chloride values.
Dissolved inorganic carbon (DIC) concentrations were determined with a Model 5011 UIC coulometer and quantified relative to a seawater certified reference material (CRM) with a relative standard deviation (RSD) of 4 percent (%) relative to the CRM value (2.2 millimolar, mM). The stable carbon isotopic content of the DIC was measured with a Thermo-Finnigan DELTAplus XP IRMS with an analytical error (1-sigma) of 1.1 per mil.
Headspace methane concentrations were determined using a Shimadzu 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 a relative standard deviation of 2 percent (%).
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.
DOC concentration and d13C were analyzed by high-temperature combustion-isotope ratio mass spectrometry (HTC-IRMS) at the USGS-WHOI Dissolved Carbon Isotope Lab (DCIL). The DCIL HTC-IRMS system consists of an OI 1030C total carbon analyzer and a Graden molecular sieve trap interfaced to a Thermo-Finnigan DELTA-PLUS XL IRMS. DOC concentrations are reported with an RSD of less than 5 percent (%) of the measured value. Stable carbon isotope ratios for DIC, methane and DOC are reported in the standard delta-notation relative to VPDB (Vienna Pee Dee Belemnite) with a 1-sigma deviation of less than 0.5 per mil.
All sample analyses were performed by David Brankovits under the supervision of John Pohlman. More details about the laboratory analyses are described in the Geochemical Analysis portion of the Methods section of Brankovits and others, 2017). Sample processing occurred between 2014 and 2015.

Overview_Description:
Entity_and_Attribute_Overview:
The dataset contains one Excel file (geochem_2013-2015.xlsx) with one tab (geochem_2013-2015), and one CSV file (geochem_2013-2015.csv) that corresponds to the tab with the same name in the spreadsheet. The first row (header line) of the CSV file contains the column labels (and is the same information as these attributes). The first row of the Excel spreadsheet contains a header line that includes a short description of the project and the years the data were obtained, the second row indicates the mode of sampling, the third row is the column label with special characters, and the fourth row is the column label without special characters (and it corresponds with the first row of the CSV file). Additionally, a browse graphic (geochem.jpg) and the CSDGM metadata in XML format are provided.
