This dataset summarizes impairment status for HUC12 watersheds at the CONUS scale using the EPA publicly available Assessment, Total Maximum Daily Load (TMDL) Tracking and Implementation System (ATTAINS) geospatial package and the USGS Watershed Boundary Dataset (WBD). ATTAINS is an online system maintained by the EPA containing information about the condition of the Nation’s surface waters, as reported by individual states. These data were downloaded in October 2023 and primarily reflect 2022 stream conditions. Because of the varying data types that exist in the database, an independent methodology was developed for summarizing impairment status for HUC12 watersheds using the USGS WBD as detailed in this metadata...
This data release child item contains fiber-optic distributed temperature sensor (FO-DTS) data collected along the western unwalled shoreline of the Bremerton Naval Complex, Bremerton, Washington, USA from July 30, 2020, to August 11, 2020. Continuous profiles of water temperature were collected along a spatially georeferenced fiber optic cable deployed in an out-and-back U-shape with approximately 2- meter distance between the parallel cable lengths by a Sensornet® Oryx DTS FO-DTS (Fiber-optic distributed temperature sensor). Data were collected in a single ended configuration with two channels, Channel_1 and Channel_2, where water temperature was spatially averaged over 1.01- meter linear intervals by the Oryx...
