//////////////////////////////////////////////////// Metadata for ChemometricSalmonCreekDOCdata.xls //////////////////////////////////////////////////// This datafile contains fluorescence indices and the results of a parallel factor analysis (PARAFAC) performed on samples collected within the Salmon Creek Watershed in Sonoma County, Califonia. Please see Woelfle-Erskine et al. (2017) for site location details. The present dataset is provided in support of Larsen and Woelfle-Erskine (in review). Data were collected from 2013-2016 in Fay Creek and Tannery Creek, both second-order tributaries of Salmon Creek. The accompanying CSV file has one row of column headers. Columns are defined as described in the data dictionary below. //////////////////////////////////////////////////// Data Dictionary: 1. Sample name: Name of the fluorescence excitation-emission scan datafile 2. Creek: Designates tributary or watershed within which sample was collected. Values = Fay (Fay Creek); Tannery (Tannery Creek); Fw (Fay Creek watershed); Ftrib (Tributary of Fay Creek); Tw (Tannery Creek watershed); Ttrib (Tributary of Tannery Creek) 3. Date: Sample collection date; mm/dd/yyyy 4. Water year: The water year in which the sample was collected. Water years are October-September and are named for the year corresponding to Jan-September. 5. Month: Numeric month in which sample was collected. 6. Type: Type of sample. Values = well; spring; surface (surface water); piezo (piezometer) 7. Depth below streambed (m): Depth beneath the substrate at which sample was collected. Surface-water samples are assigned a value of 0. Unknown depths (e.g., in some wells) are assigned a blank. 8. Status: Status of surface-water connectivity within the stream. Values = flowing, disconnected, trickling, and dry. 9. OP C1: Fmax value of original PARAFAC component 1 (see Larsen and Woelfle-Erskine, in review, for description). 10. OP C2: Fmax value of original PARAFAC component 2 (see Larsen and Woelfle-Erskine, in review, for description). 11. OP C3: Fmax value of original PARAFAC component 3 (see Larsen and Woelfle-Erskine, in review, for description). 12. OP C4: Fmax value of original PARAFAC component 4 (see Larsen and Woelfle-Erskine, in review, for description). 13. OP C5: Fmax value of original PARAFAC component 5 (see Larsen and Woelfle-Erskine, in review, for description). 14. FI: Fluorescence index 15. HIX: Humification index 16. BIX: Biological (a.k.a. freshness) index 17. C1: Fmax value of Cory and McKnight (2005) PARAFAC component 1 (see Larsen and Woelfle-Erskine, in review, for description) 18. C2: Fmax value of Cory and McKnight (2005) PARAFAC component 2 (see Larsen and Woelfle-Erskine, in review, for description) 19. C3: Fmax value of Cory and McKnight (2005) PARAFAC component 3 (see Larsen and Woelfle-Erskine, in review, for description) 20. C4: Fmax value of Cory and McKnight (2005) PARAFAC component 4 (see Larsen and Woelfle-Erskine, in review, for description) 21. C5: Fmax value of Cory and McKnight (2005) PARAFAC component 5 (see Larsen and Woelfle-Erskine, in review, for description) 22. C6: Fmax value of Cory and McKnight (2005) PARAFAC component 6 (see Larsen and Woelfle-Erskine, in review, for description) 23. C7: Fmax value of Cory and McKnight (2005) PARAFAC component 7 (see Larsen and Woelfle-Erskine, in review, for description) 24. C8: Fmax value of Cory and McKnight (2005) PARAFAC component 8 (see Larsen and Woelfle-Erskine, in review, for description) 25. C9: Fmax value of Cory and McKnight (2005) PARAFAC component 9 (see Larsen and Woelfle-Erskine, in review, for description) 26. C10: Fmax value of Cory and McKnight (2005) PARAFAC component 10 (see Larsen and Woelfle-Erskine, in review, for description) 27. C11: Fmax value of Cory and McKnight (2005) PARAFAC component 11 (see Larsen and Woelfle-Erskine, in review, for description) 28. C12: Fmax value of Cory and McKnight (2005) PARAFAC component 12 (see Larsen and Woelfle-Erskine, in review, for description) 29.
