Contributing zones of the San Antonio, Barton Springs, and Northern segments of the Edwards Aquifer Contributing zones of the San Antonio, Barton Springs, and Northern segments of the Edwards Aquifer
The Edwards aquifer is a karst aquifer system that is a primary water source for a large part of central Texas including the city of San Antonio, Texas. These vector geospatial data represent the geographic extent of the contributing zones for the Northern, Barton Springs, and San Antonio segments of the Edwards aquifer. The contributing zone is defined as the drainage area of the...
Cross-Section Geometry and Sediment-Size Data from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado, 2019 Cross-Section Geometry and Sediment-Size Data from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado, 2019
This dataset contains cross-section geometry and sediment-size data collected in the fall of 2019 from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado. Six cross sections were surveyed using Real-Time Kinematic Global Navigation Satellite System (RTK-GNSS) methods to document channel geometry below Paonia Reservoir. One cross section was surveyed on...
GeoNatShapes: a natural feature reference dataset for mapping and AI training GeoNatShapes: a natural feature reference dataset for mapping and AI training
These data were compiled for the use of training natural feature machine learning (GeoAI) detection and delineation. The natural feature classes include the Geographic Names Information System (GNIS) feature types Basins, Bays, Bends, Craters, Gaps, Guts, Islands, Lakes, Ridges and Valleys, and are an areal representation of those GNIS point features. Features were produced using heads...
Hawaii Island, Hawaiian hoary bat acoustic data pre- and post-koa moth outbreak, 2007-2013 Hawaii Island, Hawaiian hoary bat acoustic data pre- and post-koa moth outbreak, 2007-2013
We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lupahoehoe Forest Reserve on Hawai'i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level that operated...

One data set "Point Locations of Radio-collared female northern Yellowstone mule deer" provides details about the date and time of relocations of radio-collared female northern Yellowstone mule deer along with location coordinates. Habitat types with...
Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River
The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013; Domanski, 2020). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions...
