The primacy of dissolved organic matter to aquatic light variability

This dataset contains eigenanalyses results for apparent optical property observations of aquatic environments. Eigenanalyses were conducted to assess the primary sources of variability in the aquatic light field, and the results are associated with the Biogeosciences publication Houskeeper and Hooker (2025). Methodological details, including underlying dataset descriptions, plus post-processing and quality control, are provided in the associated publication. Descriptions of the underlying datasets used for conducting the eigenanalyses are also summarized in the dataset readme., , # Eigenanalyses of Aquatic Optical Property Datasets

This dataset contains the results of eigenanalyses conducted using apparent optical property observations of aquatic environments. The eigenanalyses were conducted to assess the primary sources of variability in the aquatic light field, and the results are associated with the *Biogeosciences* publication Houskeeper and Hooker (2025).
