Geochemical data for fluids collected in Acoculco Geothermal Field

The dataset CO2_flux_measurements_Acoculco contains data on CO2 fluxes, coordinates (UTM), air temperature, atmospheric pressure measured in selected sites belonging to the Acoculco Geothermal Field: in particular, the areas named Lagunilla, Alcaparrosa, Los Azufres and also the area between them were investigated. CO2 flux measurements were performed using the accumulation chamber method.

The dataset Field_meas_Acoculco_waters reports the ID, coordinates (UTM), Altitude (m.a.s.l.), temperature, flow rate, pH, Electrical Conductivity and Dissolved Oxygen for water samples collected in the central sector of the Acoculco geothermal field, but also in other sectors located inside and outside the Acoculco caldera. Total depth is also included for samples collected from water wells.

The dataset Chemical_isotopic_data_Acoculco_waters reports major and minor chemical components and stable isotopic composition for hydrogen and oxygen determined in collected water samples in Acoculco geothermal field. Calculated partial pressures (in bars and log10-value) and CO2 concentrations of dissolved CO2 were also included.

The dataset Chemical_isotopic_data_Acoculco_gas reports chemical and isotopic data for collected samples from Los Azufres and Alcaparrosa natural gas manifestations.

数据集CO2_flux_measurements_Acoculco收录了阿科库尔科地热田（Acoculco Geothermal Field）选定测点的观测数据，涵盖二氧化碳通量（CO2 flux）、通用横轴墨卡托坐标系（UTM）坐标、气温与大气压强；本次调研覆盖了拉古尼利亚（Lagunilla）、阿尔卡帕罗萨（Alcaparrosa）、洛斯阿苏弗雷（Los Azufres）及其交界区域。所有二氧化碳通量测量均采用累积室法（accumulation chamber method）完成。

数据集Field_meas_Acoculco_waters收录了阿科库尔科地热田中部及破火山口（caldera）内外其他区域采集的水样数据，包含水样编号、通用横轴墨卡托坐标系（UTM）坐标、海拔（米，高出海平面，m.a.s.l.）、水温、流速、pH值、电导率（Electrical Conductivity）与溶解氧（Dissolved Oxygen）；对于水井采集的水样，还额外包含总深度信息。

数据集Chemical_isotopic_data_Acoculco_waters收录了阿科库尔科地热田采集水样的主量与微量化学成分、氢氧稳定同位素组成数据；同时包含计算得到的分压（单位：巴，bar）、以10为底的对数值（log10-value）以及溶解态二氧化碳浓度。

数据集Chemical_isotopic_data_Acoculco_gas收录了采自洛斯阿苏弗雷（Los Azufres）与阿尔卡帕罗萨（Alcaparrosa）天然气显示（natural gas manifestations）的样品的化学与同位素数据。
