WHONDRS S19S: Global River Surface Water Chemistry and Organic Matter Data

July to September 2019 sampling of surface water from 97 globally distributed river corridor systems. The dataset includes high-resolution dissolved organic matter characterization via FTICR-MS, NPOC, stable isotopes, anions, bacterial abundance, and DIC, produced by the Pacific Northwest National Laboratory. Data packages were updated multiple times through August 2023.

Use Cases

• Characterizing dissolved organic matter composition based on FTICR-MS data.
• Analyzing relationships between bacterial abundance and water chemistry parameters like NPOC and anions.
• Modeling watershed biogeochemical function using stable water isotope (O and H) data.
• Investigating links between core/transient metabolomes and physical watershed properties.

Strengths

• Samples from 97 globally distributed river corridor systems.
• Includes high-resolution FTICR-MS data from a 12 Tesla instrument.
• Multiple data package updates through 2021, 2023, and 2023 adding new data types and documentation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset does not include results from the sediment samples collected at the same sites.
