Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019 Evaluating changes in Piping Plover home ranges following coastal restoration at Whiskey Island and Caminada Headland, Louisiana from 2013 to 2019
Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed Piping Plover (Charadrius melodus). Therefore, we...
Insights into the formation of thucholites Insights into the formation of thucholites
Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...
Spatial covariance tracks grassland bird community occupancy in fragmented grasslands Spatial covariance tracks grassland bird community occupancy in fragmented grasslands
Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...
Oceanographic Time Series Measurements Collected at Madeira Beach, Florida Oceanographic Time Series Measurements Collected at Madeira Beach, Florida
The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...
Santa Rosa Plain integrated hydrological model: simulating the hydrological system of the Santa Rosa Plain, California with analysis of future climate scenarios Santa Rosa Plain integrated hydrological model: simulating the hydrological system of the Santa Rosa Plain, California with analysis of future climate scenarios
The U.S. Geological Survey (USGS) conducted a study in cooperation with the Sonoma County Water Agency to assess the water resources of the SRPW and develop tools to better understand the groundwater and surface-water systems in the watershed. The foundation of these tools is the development and application of the Santa Rosa Plain hydrologic model (SRPHM) using GSFLOW to simulate...
Dynamic rating model archive Dynamic rating model archive
Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...
