Bird point count and vegetation survey data from grassland sites in southern Iowa Bird point count and vegetation survey data from grassland sites in southern Iowa
This dataset contains records from bird point count and vegetation surveys conducted at 71 sites in southern Iowa in 2022 and 2023. All sites had recently implemented a management practice aimed at increasing habitat quality for northern bobwhite. We conducted surveys at 1-3 points per site and visited each point 3 times between May 15 and July 31 each year. Some sites were visited in...
Self-calibrating Palmer Drought Severity Index values averaged per water year with associated streamflow permanence data products for the HUC17 Pacific Northwest Region Self-calibrating Palmer Drought Severity Index values averaged per water year with associated streamflow permanence data products for the HUC17 Pacific Northwest Region
This data release includes estimated Self-Calibrated Palmer Drought Severity Index (scPDSI) values and ancillary information for three data products that had previously been developed for the Pacific Northwest Region (HUC 17). The data products are stored in three child items: 1. National Hydrography Dataset High Resolution Flowlines: This child item contains the flowlines in the...
Campaign GNSS measurements on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory in 2022 Campaign GNSS measurements on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory in 2022
This release includes data collected during campaign GNSS surveys at Kīlauea and Mauna Loa on the Island of Hawaiʻi in 2022. It includes data from a total of 63 sites occupied from January 1 to December 31, 2022. For each site, we include its measured raw data in daily files, Receiver INdependent EXchange (RINEX) files for each day, field log sheet(s), and associated metadata information...
Shore Proximal Marsh Sediment Deposition and Ancillary Data From Grand Bay National Estuarine Research Reserve, Mississippi, From October 2020 to January 2023 Shore Proximal Marsh Sediment Deposition and Ancillary Data From Grand Bay National Estuarine Research Reserve, Mississippi, From October 2020 to January 2023
To better understand sediment deposition in marsh environments, scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) selected five marsh study sites (Sites 5, 6, 7, 8, and 9) and four nearshore estuarine study sites (Sites 8S, 8D, 9S, 9D) along the Point Aux Chenes Bay shoreline of the Grand Bay National Estuarine Research Reserve...
Application of the WRF-Hydro Modeling System for the Conterminous United States at the NHDPlus version 2 Spatial Resolution Using the Bias Adjusted Version of the CONUS404 Atmospheric Forcings (CONUS404BA), Water Years 2010-2021 Application of the WRF-Hydro Modeling System for the Conterminous United States at the NHDPlus version 2 Spatial Resolution Using the Bias Adjusted Version of the CONUS404 Atmospheric Forcings (CONUS404BA), Water Years 2010-2021
This data release contains inputs for and outputs from a hydrologic simulation for the conterminous United States (CONUS) using the WRF-Hydro modeling system version 5.2.0 (Gochis and others, 2020) at the NHDPlus version 2 spatial resolution. This simulation was developed to provide water budget estimates for the period 10/1/2009 to 9/30/2021 using the bias adjusted version of the...
Loss of acclimation response of brook trout acclimated to three thermal regimes for 2-years and then moved to a common colder temperature Loss of acclimation response of brook trout acclimated to three thermal regimes for 2-years and then moved to a common colder temperature
This dataset contains records of body sizes and critical thermal maximum test results of brook trout reared for 2 years under three different temperature regimes (+0 °C (the average daily water temperature of a nearby long-term study site), as well as +2 °C and +4 °C above that daily average), moved to a common colder temperature (~15 °C), and thermal tolerance measured using a critical...
