Monitoring O. mykiss Life Stages on the Stanislaus River 2021-2025
This study is designed to partly address steelhead conservation measures outlined in the U.S. Bureau of Reclamation's Proposed Action for the Long-Term Operation of the CVP. This effort is funded under the Central Valley Project Improvement Act (CVPIA) authority Provision 3046 (g)(4), which states the primary purpose of this effort shall be to support the Secretary's efforts in fulfilling the requirements of this title through improved scientific understanding concerning, but not limited to, measures needed to restore anadromous fisheries to optimum and sustainable levels in accordance with the restored carrying capacities of Central Valley rivers, streams, and riparian habitats. Conceptual and quantitative work described in this report encompass multiple O. mykiss life-stages and transitions among life stages. The geographic scope of the report includes the Lower Stanislaus River, extending from Goodwin Dam down to the confluence of the San Joaquin River. The goal of this study is to develop a framework for monitoring life stages, and transitions among life stages, to quantify how water project operations and environmental variation influence life history expression, abundance, and population productivity. Data is recorded in a combination of paper to computer files and electronic-only files. Annual reports summarize the survey findings. While this project is ongoing, this is a completed dataset for the collection sessions performed in the years 2021- 2025.
Hourly soil moisture, soil temperature, groundwater temperature, and groundwater stage height measurements from 9 Hillslope Study sites located in Macon County, North Carolina, within the Upper Little Tennessee River Basin
The Hillslope Study was established to directly link land use impacts to streamwater quality in the southern Appalachian Mountains. Nine sites were selected in the Little Tennessee River watershed in Macon County, NC, representing four land use types: forest, mountain development, traditional valley, and large river valley. At each of these sites, three subsurface flowpaths were identified, and four plots were established along the flowpath following the elevation gradient. At seven of the nine sites, the three lower elevation plots at one of the subsurface flowpaths had ground water wells installed in order to measure groundwater stage and temperature along an elevational gradient. Additional sensors were installed adjacent to the groundwater wells to measure soil moisture at 0-30 cm and 30-60 cm below the ground surface uphill and downhill of the well, and soil temperature at 5 cm below the ground surface. Measurements were taken every 60 seconds and output as hourly averages. Data were used as part of the Regional HydroEcological Simulation System (RHESSys) ecohydrologic model. Please see the accompanying well construction data for additional groundwater well information.

Fig. 5 in The changing course of the Amazon River in the Neogene: center stage for Neotropical diversification
Fig. 5. Summary of hydrological connections among major sedimentary basins of northern South America through the Neogene. Caribbean-draining Andean foreland basins in orange. Atlantic-draining basins contributing to transcontinental Amazon in yellow. Other north Atlantic-draining basins in shades of green. South Atlantic-draining (La Plata) basins in blue. Connectivity as a block-design landscape evolution model at right preserving general spatial relationships. Red arrows depict predominant direction of sediment and water flow. Double-headed arrow indicates bidirectional connections during that time interval. Vicariance events when basins of the same color change to different colors between time intervals; geodispersal events when basins with different colors change to same color. Connections of basins in grey are poorly constrained by avai- lable data. Basin in white is entirely marine. "W. Amazon" refers to the combined Putumayo, Napo, Marañón and Ucayali sedimentary basins, "Llanos" to the combined Llanos, and Barinas/Apure basins, "Amazonas" to the combined Amazonas and Marajo basins, and "Essequibo" to the Proto-Berbice basin. Sedimentary basins with four letter abbreviations at left in top panel. Base-maps with modern coastlines and topography to facilitate orientation.

ABoVE: River Ice Breakup and Freeze-up Stages, Yukon River Basin, Alaska, 1972-2016
This dataset provides estimates of river ice breakup and freeze-up stages along selected reaches of the Yukon and Tanana Rivers in the Yukon River Basin in interior Alaska from 1972-2016. Time series of Landsat satellite images were visually interpreted to identify the day of year and characteristics of the different stages of river ice seasonality. The stages of breakup or freeze-up were distinguished from one another based on the spatial extent and patterns of open water and ice cover. Images were displayed as false color composites, with the shortwave infrared (SWIR), near infrared (NIR), and green bands represented by red, green, and blue.
