Winter Sediment Oxygen Demand and Sediment Characteristics in Pools 4, 8, and 13 of the Upper Mississippi River, 2022 Winter Sediment Oxygen Demand and Sediment Characteristics in Pools 4, 8, and 13 of the Upper Mississippi River, 2022
Many ecological processes affect availability of winter dissolved oxygen (DO) concentrations in rivers, a key feature of overwintering fish habitat. Sediment oxygen demand (SOD) contributes to DO depletion, particularly during ice-covered periods, and may cause hypoxic conditions in backwater lakes, affecting availability of suitable overwintering habitat. Understanding drivers of SOD on...
Site characteristics: postfire soil hydrologic and biogeochemical response and recovery in northern California, USA Site characteristics: postfire soil hydrologic and biogeochemical response and recovery in northern California, USA
California’s wildfires are setting historic records for length, size, and severity (Safford and others, 2022, Kreider and others, 2024). These wildfires are altering soil processes like infiltration rates and carbon cycling over increasingly large areas (Staley and others, 2017; Kelly and others, 2020; Baur and others, 2024; Dow and others, 2024). In northern California, it is unclear...
Workflow and data supporting ensemble-based history matching and uncertainty quantification for selected watersheds from the National Hydrologic Model Workflow and data supporting ensemble-based history matching and uncertainty quantification for selected watersheds from the National Hydrologic Model
History matching of large hydrologic models is challenging due to data sparsity and non-unique process combinations (and associated parameters) that can produce similar model predictions. We developed an ensemble-based history matching and uncertainty quantification approach using an iterative ensemble smoother (iES) method for three cutouts of the National Hydrologic Model (NHM) and...
Total Applied Surface Water and Groundwater Irrigation Data from Four Areas to Support Analysis for Estimating Irrigation Consumptive Use for the Conterminous United States Total Applied Surface Water and Groundwater Irrigation Data from Four Areas to Support Analysis for Estimating Irrigation Consumptive Use for the Conterminous United States
This digital dataset contains irrigation applications and consumptive use at the agricultural-field scale (average 173 acres) and twelve-digit watershed scale (HUC12) for four regions in the conterminous United States representing calendar years 2000-2020. Agricultural field-scale irrigation depths of applied groundwater and surface water for selected agricultural fields were compiled...
InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024 (ver. 1.1, January 2026) InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024 (ver. 1.1, January 2026)
This dataset contains InSAR (Interferometric Synthetic Aperture Radar) time series data of the deformation state of Mauna Loa from 2015 to 2024. There are four total InSAR timeseries: A descending orbital perspective from 2015 to 2022 created using LiCSBAS (HI_filt_des.h5) A ascending orbital persepctive from 2015 to 2022 created using LiCSBAS (HI_filt_asc.h5) A descending orbital...
Hydrogeologic regions of the conterminous United States Hydrogeologic regions of the conterminous United States
This data release contains shapefiles of hydrogeologic regions of the conterminous United States. The United States Geological Survey (USGS) is developing a National Extent Hydrogeologic Framework. In support of that effort, principal aquifers (PA) (USGS, 2003) and secondary hydrogeologic regions (SHR) (Belitz and others, 2018a) in the conterminous United States were combined into a...
