Organic Matter Concentration and Composition in November 2021 and April 2022 from 12 Streams Impacted by the 2020 Holiday Farm

This dataset represents results from a field study aiming to understand storm induced transport of pyrogenic materials to streams impacted by varying degrees of burn severity. Time series samples were collected at 5 sites within the McKenzie River Watershed (Oregon, USA) whose catchment were each completely engulfed by the 2020 Holiday Farm Fire. An additional 7 sites were sampled once during the storm. The samples were collected during storm events in November 2021 and April 2022 during storm events, approximately 12- and 17-months post-fire. Samples were characterized for dissolved organic carbon and optics (absorbance and fluorescence). Sampling also occurred in November 2020, and those data (referred to as "Year 1") can be found in a separate data package (doi: 10.15485/1869708). The data within this data package, which includes samples collected in November 2021 and April 2022, are collectively referred to as "Year 2". This dataset contains (1) file-level metadata; (2) data dictionary; (3) data package readme; (4) metadata; (5) methods information; (6) dissolved organic carbon (DOC, measured as non-purgeable organic carbon, NPOC) data; (7) excitation emission matrix (EEM) methods; and (8) a sub-folder with processed excitation emission matrix (EEM) data. The sub-folder contains two additional folders; the Absorbance and Fluorescence folders contain the processed EEMs absorbance and fluorescence data respectively. This package contains the following file types: csv, txt, pdf.
