Title

Fluvial hydrochemistry, CO2 efflux and delta 13C-Dissolved inorganic carbon data for the Houzhai Catchment, Southwest China, 2016-2018

Abstract

The dataset contains measurements of CO2 efflux from streams, springs, reservoirs and ponds in the Houzhai catchment, a typical karst catchment in the karst region of SW China. Data were obtained via direct, field-based measurements during monthly campaigns conducted between January 2016 and February 2017. Also included are water chemistry parameters (water temperature, pH, dissolved oxygen, electronic conductivity, concentration of dissolved inorganic carbon (DIC) and isotopic composition of dissolved inorganic carbon (δ13C-DIC)) and flow velocity (determined prior to in-situ flux measurements). The data were collected under the NERC-funded project: Addressing a significant knowledge gap in fluvial system atmospheric CO2 efflux: the contribution from karst landscapes (NE/N002806/1).

Lineage

All data were generated by the authors. The flux rate was measured over four minutes, repeated three times to obtain a mean rate of increase.For data generated via mass spectrometry, beam areas of all measured mass-to-charge ratios were corrected for drift offline using control standards. All calculations were checked for errors before data was accepted.
