Submersed Macrophyte Biomass Estimates in Pools 4, 8 and 13 of the Upper Mississippi River, 1998-2018 Submersed Macrophyte Biomass Estimates in Pools 4, 8 and 13 of the Upper Mississippi River, 1998-2018
System-scale restoration efforts within the Upper Mississippi River Restoration Program have included annual monitoring of submersed aquatic vegetation (SAV) since 1998 in four representative reaches spanning approximately 440 river km. We developed predictive models relating monitoring data (site-scale SAV abundance indices) to diver-harvested SAV biomass, used the models to back...
Maine Lidar-Derived Watersheds Maine Lidar-Derived Watersheds
Lidar Digital Elevation Models (DEMs) at 2-meter resolution have been used to derive watershed boundaries for the State of Maine. Geographic Information Systems (GIS) software was used to hydrologically enforce lidar DEMs and delineate watershed boundaries at pre-existing pour point locations (Price, 2016). The watershed boundaries are comparable in size to the 12-digit Hydrologic Unit...
Arthropod Abundance and Shrub Cover and Height on the Seward Peninsula, Alaska, 2015-2016 Arthropod Abundance and Shrub Cover and Height on the Seward Peninsula, Alaska, 2015-2016
This data set contains information (in three tables) with numbers and biomass of invertebrates (primarily arthropods) collected in pitfall-trap arrays and sweep-net samples on a series of plots (n = 13 total) at one coastal and one interior study site on the Seward Peninsula in northwestern Alaska during the summers of 2015 and 2016. Associated data on the horizontal cover and height of...
Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2020 Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2020
Observations of irrigated agricultural land within the Harquahala Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ three times in 2020 on first on March 11th, then on May 27th, and finally on August 11th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program...
Yuma Ridgway's Rail (Rallus obsoletus yumanensis) Population Surveys, Rail Movement, and Potential Habitat at the Salton Sea of California Yuma Ridgway's Rail (Rallus obsoletus yumanensis) Population Surveys, Rail Movement, and Potential Habitat at the Salton Sea of California
Data were obtained as part of a project assessing risk to the federal and California listed endangered Yuma Ridgway's rail (Rallus obsoletus yumanensis) populations resulting from selenium contaminated agricultural runoff and to inform habitat restoration and management decisions. Four data sets were produced and used to analyze patterns of Yuma Ridgway's rail (Rallus obsoletus...
