Abstract
This HydroShare collection brings together the 32 data resources used in the study “Hydrologic controls on diel dissolved oxygen regimes in non-perennial streams.” The resources cover eight non-perennial watersheds spanning a climatic and hydrologic gradient across the Mountain West, Great Plains, and Southeastern Forests of the United States: Johnston Draw and Gibson Jack Creek in Idaho; Kings Creek, Shane Creek, and Youngmeyer Ranch in Kansas; and Shambley Creek, Paint Rock, and Talladega in Alabama. Data were collected primarily from 2021 through 2024 as part of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project. For each watershed, the collection links environmental and geospatial site information; spatially distributed Stream Temperature, Intermittency, and Conductivity (STIC) datasets used to characterize surface-water presence and active drainage-network extent; continuous outlet water-quality measurements; and continuous stage and discharge records. Most sensor measurements were recorded at 15-minute intervals. Together, these resources document the hydrologic, physicochemical, and spatial observations underlying the study’s characterization of diel dissolved oxygen regimes and evaluation of their environmental controls. Individual resources include site-specific metadata, methods, quality-control information, and data files to support reuse and reproducible analysis.
