Diel stream hydrology and in-situ hydrochemistry during a 24 h survey in the Wiesent karst headwater, northern Bavaria, Germany (August 2023)

This dataset contains diel hydrological and in-situ hydrochemical measurements collected at three sites along the Wiesent karst headwater stream in northern Bavaria, Germany, between 21 and 22 August 2023. Parameters include location information, stream width and depth, discharge, water temperature, pH, electrical conductivity, and dissolved oxygen. Measurements were conducted at 4 h intervals over a 24 h period to assess short-term hydrochemical variability along the spring-to-stream transect.

Stream hydrology and in-situ hydrochemistry over 15 months along a spring-to-stream transect in the Wiesent karst headwater, northern Bavaria, Germany (March 2023-May 2024)

This dataset contains location information, field-measured hydrological and in-situ hydrochemical parameters from stream water samples collected at 13 sampling sites along the first 3.25 km of the Wiesent karst headwater stream in northern Bavaria, Germany, from March 2023 to May 2024. Parameters include latitude, longitude, elevation, distance to the spring, stream width and depth, discharge, water temperature, pH, electrical conductivity, redox potential, and dissolved oxygen.

Carbon chemistry, stable carbon and oxygen isotopes, and calculated pCO2 and CO2 fluxes over 15 months along the Wiesent karst headwater stream in northern Bavaria, Germany (March 2023-May 2024)

This dataset contains alkalinity, dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) concentrations, d13C values of DIC, DOC, and particulate organic carbon (POC), d18O values of dissolved oxygen, and calculated partial pressure of CO2 (pCO2), CO2 fluxes, and gas-transfer velocity (k600) from stream-water samples collected at 13 sites along the first 3.25 km of the Wiesent karst headwater stream in northern Bavaria, Germany, from March 2023 to May 2024. The dataset supports analyses of carbonate-system dynamics, oxygen cycling, and CO2 evasion under varying hydroclimatic conditions.

Diel carbon chemistry, stable carbon and oxygen isotopes, calculated pCO2 and CO2 fluxes during a 24 h survey in the Wiesent karst headwater, northern Bavaria, Germany (August 2023)

This dataset contains diel measurements of alkalinity, dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), particulate organic carbon (POC), d18O values of dissolved oxygen, and calculated partial pressure of CO2 (pCO2), calculated CO2 fluxes, and calculated gas-transfer velocity (k600) from stream-water samples collected at three sites along the Wiesent karst headwater stream in northern Bavaria, Germany, between 21 and 22 August 2023. Measurements were conducted at 4 h intervals over a 24 h period to assess short-term variability in carbon and oxygen cycling and CO2 evasion.

Major ions and trace metal concentrations over 15 months along the Wiesent karst headwater stream in northern Bavaria, Germany (March 2023-May 2024)

This dataset contains concentrations of fluoride, chloride, sulfate, nitrate, sodium, magnesium, potassium, silicon, calcium, aluminium, manganese, and iron from stream-water samples collected along the first 3.25 km of the Wiesent karst headwater stream in northern Bavaria, Germany, from March 2023 to May 2024. The dataset supports analyses of hydrochemical variability under varying hydroclimatic conditions.

Hydrology, hydrochemistry, carbon dynamics, and calculated pCO2 and CO2 fluxes from the Wiesent, a karst headwater stream in Germany, 2023-2024

These datasets contains hydrological, hydrochemical, and biogeochemical measurements collected along a 3.25 km spring-to-stream transect in the Wiesent karst headwater in northern Bavaria, Germany, between March 2023 and May 2024. Monthly observations at 13 sites include field parameters (discharge, pH, electrical conductivity, redox potential, and water temperature), major ions and trace metals, dissolved and particulate carbon pools (DIC, DOC, POC), stable carbon and oxygen isotopes (δ13CDIC/DOC/POC [‰ VPDB], δ18ODO [‰ VSMOW]), and calculated partial pressure of CO2 (pCO2), CO2 fluxes, and gas-transfer velocities. In addition, a 24 h diel survey conducted in August 2023 provides the same field, carbon-system, stable isotope, pCO2, FCO2 and gas-transfer parameters at three representative sites along the transect at 4 h intervals. The dataset provides a basis for studies of karst hydrochemistry, carbon and oxygen cycling, carbonate buffering, spring-water and surface-water interactions, and CO2 evasion under varying hydroclimatic conditions.

Grain size distribution of soil samples from the White Main catchment, Germany, November 2024
