The WHONDRS Summer 2019 Sampling (S19S) Campaign collected samples in 97 globally distributed river corridor systems between July and September 2019. Surficial streambed sediments were collected at three locations within each site (upstream, midstream, and downstream). Surface water was collected at the downstream site. This dataset includes a portion of the data types produced from the surface water samples and does not include any results from the sediment. Sediment data can be found at https://data.ess-dive.lbl.gov/view/doi:10.15485/1729719. Future datasets from this study will include hydrologic and microbial data from the surface water and sediment. The S19S campaign was designed with the science community to ask questions associated with links among core/transient metabolomes, microbial metabolism, biogeochemical function, and physical properties of watershed and river corridor systems. This dataset contains (1) high resolution characterization of dissolved organic matter from surface water via 12 Tesla Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) through the Environmental Molecular Sciences Laboratory (EMSL; https://www.pnnl.gov/environmental-molecular-sciences-laboratory); (2) non-purgeable organic carbon (NPOC); (3) stable water isotopes (O and H); (4) specific conductivity (SpC), total nitrogen (TN), and anions; (5) flow cytometry bacterial abundance data; (6) dissolved inorganic carbon (DIC) data; (7) metadata, including international generic-sample number (IGSN) mapping file; (8) file-level metadata (flmd); and (9) data dictionary (dd). The FTICR-MS files are .xml, and the data package includes instructions for using Formularity (https://omics.pnl.gov/software/formularity) and an R script to process the data based on the user’s specific needs. All other files are .csv, .pdf, or .txt. This data package was updated in July 2021 to add SpC, TN, and anion data and accompanying documentation. This data package was updated in January 2023 to add flow cytometry bacterial data, accompanying documentation, flmd, and dd. The data package was updated in February 2023 to add DIC data and accompanying documentation. The data package was updated in August 2023 to add IGSN mapping file, correct field metadata, and update accompanying documentation.
