The twin Voyager 1 and Voyager 2 spacecraft launched in August (Voyager 2) and September (Voyager 1) of 1977 and reached the Jupiter system in March (Voyager 1) and July (Voyager 2) of 1979, where they acquired images of the Galilean satellites before continuing on to Saturn. Each spacecraft was identically equipped with both wide-angle and narrow-angle slow-scan vidicon cameras that...

To better understand the pesticide exposure of bees (Bombus, Melissodes) while foraging in an agriculturally influenced landscape in Brookings County, South Dakota, bee tissue samples were collected from April/May through October in 2022 and 2023. Bees, included wild Bombus and Melissodes, were collected biweekly using blue vane traps and B. impatiens were collected from commercially...

This data release provides county-level predictions of grassland bird nesting phenology across the midcontinent of North America as a GIS shapefile. Predictions are derived from species-specific models relating nest initiation timing to geographic location, vegetation phenology, and interannual weather variability, and include estimated nesting dates for multiple percentiles of the...

This data release contains Canadian Forest Fire Danger Rating System (CFFDRS) fire weather indices calculated using bias-corrected CMIP6 daily data for the period of 1980 - 2100. The spatial domain includes the boreal ecoregion of North America.

Ground-based field monitoring meteorological stations are used to collect real-time weather and environmental data. Data parameters range from weather variables (i.e., precipitation, wind speed and direction, air temperature, relative humidity, dew point), to environmental variables (i.e., solar radiation, air density, soil conductivity), to station status data (i.e., battery voltage...

This data release documents estimates of groundwater recharge for the U.S. portion of the Salish Sea Basin in northwestern Washington. A U.S. Geological Survey Soil-Water-Balance (SWB) model (Westenbroek and others,2018) was developed for Hydrologic Unit Code 17110 to simulate the spatial distribution of net infiltration below the root zone on a daily time step from January 1, 1980...

The U.S. Geological Survey (USGS) National Water Quality Program, through the Prototyping Modeling and Assessment of Post-wildfire Water Availability project, aims to enhance the ability to assess and predict the impacts of wildfires on water supplies. Precipitation is a key driver of flooding, debris flows, and water quality responses following wildfire. The intensity, duration, and...

This data release consists of data and metadata for a forest restoration experiment investigating experimental outplanting diversity and density in previously grazed pastureland. Five replicate sites, consisting of 11 - 6x6m plots (10 experimental treatments + 1 control), were set up for this experiment. Treatments consisted of two planting densities (double and single) as well as...

The Silurian aquifer is an important water source for municipalities, industry, and rural households and communities in eastern Iowa, including Johnson County. Increasing demand for groundwater from the aquifer created a need for analytical tools tools that quantify groundwater resources and inform water-management decisions for the aquifer. The U.S. Geological Survey, in cooperation...

Meteorological data were collected at Marconi and Head of the Meadow Beaches on Cape Cod National Seashore, MA as part of a multi-year monitoring study of nearshore sand transport and white shark behavior. The overarching goal of the study is to characterize beach and nearshore morphology, assess temporal variability, and measure wave runup to calibrate USGS total water level forecasts...

The Ordovician Icebox Formation of the Winnipeg Group has been interpreted as a petroleum source rock within the Williston Basin for over 50 years. Despite limited hydrocarbon production from Winnipeg Group reservoirs and being deeply buried (located below most of the current hydrocarbon producing reservoirs), the petroleum industry continues to periodically drill wells through the...

Conodonts were collected in the southern Lake Champlain valley to aid in identifying lithostratigraphic units, determining biostratigraphic zonations, and correlating to other regions. The conodonts were identified by experts in Cambrian and Ordovician micropaleontology. Microslides/thin sections were made of different lithostraphigraphic units of the southern Lake Champlain valley to...
