Groundwater drought in the United States: Spatial and temporal variability Groundwater drought in the United States: Spatial and temporal variability
Many communities and ecosystems in the United States that are dependent on groundwater are potentially adversely affected by groundwater drought. We computed yearly groundwater-drought metrics and mean groundwater levels at well locations across the conterminous United States (CONUS), using data from wells and remotely sensed and modeled Gravity Recovery and Climate Experiment Drought...

Groundwater quality near an oil field in a stream-dominated recharge setting, California, USA Groundwater quality near an oil field in a stream-dominated recharge setting, California, USA
Alluvial valley aquifers are important sources of water supply in many areas but effects of co-located oil and gas development on these resources have not been widely reported, especially in settings where recharge is dominated by stream infiltration. Interpreting the presence of geochemical indicators in the context of hydrology, geology, and other factors provides a more complete...

Groundwater source water assessment area delineation of public supply wells in the Treasure Valley, western Idaho Groundwater source water assessment area delineation of public supply wells in the Treasure Valley, western Idaho
The Idaho Department of Environmental Quality (IDEQ) is responsible for assessing the source water for public water supply systems including the delineation of source water assessment areas for wells, which are defined as the subsurface areas contributing water to a well during a period of time. Part of the IDEQ assessment plan is to update source water assessments over time. The U.S...

Groundwater tracing used to delineate recharge areas and map karst groundwater pathways for subterranean streams at Oregon Caves National Monument and Preserve Groundwater tracing used to delineate recharge areas and map karst groundwater pathways for subterranean streams at Oregon Caves National Monument and Preserve
Oregon Caves National Monument and Preserve in southwestern Oregon is a 4,554-acre area managed by the National Park Service that is home to several cave systems, including Oregon Caves, which is the longest cave in Oregon, with 3.03 miles of mapped passages. Because of the interconnected nature of karst hydrologic systems, it is critical to understand the areas that can influence water...

Groundwater-level elevations in the bedrock aquifers of the Denver Basin aquifer system, Elbert County, Colorado, 2015–23 Groundwater-level elevations in the bedrock aquifers of the Denver Basin aquifer system, Elbert County, Colorado, 2015–23
Water users in Elbert County, Colorado, rely on groundwater from bedrock aquifers in the Denver Basin aquifer system (upper Dawson, lower Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers) for approximately half of their water uses. Withdrawals from the bedrocks aquifers have increased to meet the water use needs of expanding regional population growth and development. The U.S...

Growth and erosion of volcanic islands since 1963 analyzed by multi-sensor satellite data and historical records Growth and erosion of volcanic islands since 1963 analyzed by multi-sensor satellite data and historical records
Most volcanic activity is taking place in the oceans. Depending on water depth, eruption recurrence times and volumes, a new island can form. The power of erosional forces, the type of erupted material and the efficiency of secondary processes determine the island’s lifetime. Since the famous eruption of Surtsey (Iceland) in 1963, at least another 23 volcanic islands have appeared. Some...

Growth form and lifespan of herbaceous species mediate the role of traits in short-term drought response Growth form and lifespan of herbaceous species mediate the role of traits in short-term drought response
Increased climate variability is expected to intensify short-term drought events. Plants have evolved stress tolerance strategies involving trade-offs in resource conservation, mycorrhizal collaboration and plant size, yet how these strategies promote drought resistance across different herbaceous plant groups remains unknown. Leveraging 63 globally distributed grassland and shrubland...

Growth of a threatened desert fish becomes resource dependent when released from temperature limitation in a regulated river Growth of a threatened desert fish becomes resource dependent when released from temperature limitation in a regulated river
1. Growth of ectotherms typically positively correlates with increasing temperature towards an optimal temperature range, followed by a decline in growth when temperatures exceed the optimal temperature range for that organism. When temperature is within or close to the optimal range, food availability and other environmental factors can play important roles in modifying growth rates...

Growth, movement, and survival of precocial shorebird chicks are constrained by their environment. Growth, movement, and survival of precocial shorebird chicks are constrained by their environment.
Young animals are often less mobile than adults, while also having high energetic demands. They may therefore be more vulnerable to local-scale changes in environmental conditions. In particular, when 1 sex must grow more rapidly than the other to achieve a larger adult size, that sex may experience especially dramatic reductions in growth and survival in the face of suboptimal...

GST-1: A high-resolution global sediment thickness model GST-1: A high-resolution global sediment thickness model
Global Sediment Thickness 1 (GST-1) is a high-resolution sedimentary thickness model calculated on a 0.125° x 0.125° grid. It modifies the sediment thickness of the 1° x 1° Earth Crustal Model 1 (ECM1) by means of 3D inversions of free air gravity anomalies. GST-1 is calculated by performing structural inversions on high-density contrasts across two crustal boundaries: the sediment –...

GT-Seq panel development for species identification and parentage analysis of closely related hybridising Scaphirhynchus sturgeons GT-Seq panel development for species identification and parentage analysis of closely related hybridising Scaphirhynchus sturgeons
Hatchery supplementation is vital for conserving dwindling fish populations. Effective augmentation requires distinguishing hatchery-origin from wild individuals and accurately identifying species, particularly in systems where closely related species coexist. Genetic monitoring is key to quantifying genetic differences, but conventional markers do not distinguish hybrids, especially...

Habitat and landscape variables affecting Corbicula fluminea presence in the upper Savannah River drainage (USA) Habitat and landscape variables affecting Corbicula fluminea presence in the upper Savannah River drainage (USA)
Aquatic invasive species (AIS) are amongst the greatest threats to native aquatic biodiversity. These introduced species often thrive in human-altered environments and spread through human-mediated pathways to invade new watersheds. Corbicula fluminea is a freshwater bivalve native to southeastern Asia first introduced in North America in Seattle, WA, in 1938 and has spread to nearly...
