UV-Vis absorbance spectra of stream water samples from the White Main headwater stream, Germany, 2023–2024

This dataset contains UV-Vis absorbance spectra of stream water samples collected from the White Main headwater stream in northern Bavaria, Germany, from August 2023 to April 2024. Absorption coefficients between 230 and 700 nm were measured using a microplate spectrophotometer to characterize dissolved organic matter properties.
