Data Releases

Continuous 15-minute time-series suspended-sediment concentration (SSC) data computed from instream turbidity data. Turbidity data is managed by California Department of Water Resources (CDWR) using a YSI-6-series multi-parameter water quality sonde. Complete methods for turbidity data collection are described in attached methods document.

This Model Archive Summary (MAS) describes the development of a turbidity derived suspended-sediment concentration (SSC) time-series computation model. The MAS includes all the methods and techniques used to develop the model for USGS station 11455420 Sacramento River at Rio Vista, Ca. The time-series suspended-sediment concentration data are representative of the cross section and are...

This Model Archive Summary (MAS) describes the development of a turbidity derived suspended-sediment concentration (SSC) time-series computation model. The MAS includes all the methods and techniques used to develop the model for USGS station 11337190 San Joaquin River at Jersey Point, California. The time-series suspended-sediment concentration data are representative of the cross...

This data set consists of 96-hour survival of the mayfly Neocloeon triangulifer exposed to a variety of major ion (sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate) single salts, binary, and trinary mixtures, gluconate salts, and the organic molecule D-mannitol. Mayflies were less than 24-hours old at the beginning of tests. Mixtures consisted of pairs with either...

These data contain information on stream characteristics (intermittency and temperature), vegetation (canopy and algal cover), amphibian, reptile, and fish observations, and pathogen (amphibian chytrid fungus, Batrachochytrium dendrobatidis) prevalence, all of which are relevant for the suitability of streams in Pinnacles National Park for the reintroduction of foothill yellow-legged...

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase DR (Bera, 2024b), with the processed data for the period October 1, 2022, through September 30, 2023. This DR describes the watershed data management (WDM) database file SC23.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are...

This dataset contains a list of words that occurred at least 100 times from a news media search in LexisNexis, a large news archive database, about water bottling facilities in the U.S. from 1990 to 2024. Each word listed was classified as typically discussed in the context of the environment, the economy, both or neither. The data was used to conduct natural language processing lexicon...

Note: this data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P1EHZNHN. The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), has compiled Geographic Information Systems (GIS) datasets to assess the vulnerability of streams and stream crossings to erosion and flooding within Acadia National Park, Maine. Erosion

We digitized water on the landscape for breeding waterfowl and other wetland-associated species within Suisun Marsh (California, USA) twice each year (spring and summer) during a 38-year period (1984-2021) with remote sensing methods that combined Landsat satellite imagery (composite images) and spectral mixture analysis using Google Earth Engine. This dataset contains the amount of...

This data release presents optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL) measurements from sediment samples collected at Quaternary fault exposures in central and southeastern Washington. The primary focus of the dataset is luminescence data from three paleoseismic trenches excavated across the Dead Coyote fault scarp in the Kittitas Valley, central...

The data set contains sampling and catch data associated with an experiment to examine dispersal and short-term survival of endangered pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River of eastern Montana. The experiment was conducted as part of a flow test from Fort Peck Dam, when warm surface water from Fort Peck reservoir was released over the spillway to...
