Short summary
This study examines methodological uncertainties in FDOM (fluorescent dissolved organic matter) measurements due to filter blanks, pore sizes, and storage conditions. Results show that pre-cleaning filters and optimizing storage improve measurement reliability. These findings minimize procedural errors and provide clear guidelines for FDOM analysis, emphasizing the need for method standardization in marine biogeochemical research.
