The data set contains methane (CH4) ebullition and diffusion fluxes from three locations at Lake Neusiedl in Austria, measured weekly from late March to mid-July 2021: Channel (CH), Reed belt (RB), and Open water/Lake (OW). Fluxes are expressed daily.
Stable carbon isotopes of the ebullition gas were determined with a Picarro G2201-i.
The following in-situ water measurements were carried out during the same period and reported here: water temperature (Twater), water level (WL), dissolved oxygen (DO), pH, electric conductivity (EC), oxidation/reduction potential (ORP).
Finally, water samples were also collected weekly, at the same sites. From those samples, the following parameters were analyzed in the lab and reported here: Nitrate (NO3_-), nitrite (NO2_-), ammonium (NH4_+), orthophosphate (PO4_3-), sulfate (SO4_2-), total dissolved nitrogen (TDN), dissolved inorganic carbon (DIC), dissolved non-purgeable organic carbon (NPOC).
