Using Targeted Training Data to Develop Site Potential for the Upper Colorado River Basin from 2000 - 2018 Using Targeted Training Data to Develop Site Potential for the Upper Colorado River Basin from 2000 - 2018
Defining site potential for an area establishes its possible long-term vegetation growth productivity in a relatively undisturbed state, providing a realistic reference point for ecosystem performance. Modeling and mapping site potential helps to measure and identify naturally occurring variations on the landscape as opposed to variations caused by land management activities or...
Data for Continental-Scale Dispersal of Antimicrobial Resistant Bacteria by Alaska Landfill-Foraging Gulls Data for Continental-Scale Dispersal of Antimicrobial Resistant Bacteria by Alaska Landfill-Foraging Gulls
This data set includes information on collections of fecal samples from wild gulls (Larus spp.) at seven locations in Alaska, USA. Samples were screened for Escherichia coli (E. coli) and tested for resistance to multiple antibiotics.
Continuous gravity data from K?lauea Volcano, Hawai?i Continuous gravity data from K?lauea Volcano, Hawai?i
This Data Release contains continuous gravity records from two instruments on Kilauea Volcano, Hawaiʻ'i the HOVL gravimeter, located on the east rim of Halema'uma'u Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puu Oo crater on Kīlauea's East Rift Zone. Both instruments were collocated with GNSS stations. The HOVL gravimeter...
Zooplankton Survey of the Northern Sacramento-San Joaquin Delta, California, 2016-2018 Zooplankton Survey of the Northern Sacramento-San Joaquin Delta, California, 2016-2018
This data set contains information on zooplankton and associated environmental parameters for sampling conducted in California's northern Sacramento-San Joaquin Delta between May 2016 and April 2018. Macrozooplankton were sampled with horizontal tows (water surface) of a 50 cm-diameter conical plankton net that was 150cm long with 102um mesh. Samples were preserved in the field in 10...
Science to Inform Management of Floodplain Conservation Lands on the Middle Mississippi River Science to Inform Management of Floodplain Conservation Lands on the Middle Mississippi River
Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent...
California Groundwater Ambient Monitoring and Assessment (GAMA) Program Domestic-Supply (Shallow) Aquifer Assessment Study Unit Boundaries and Grid Cells for Assessment of Groundwater Resources (ver. 3.0, July 2025) California Groundwater Ambient Monitoring and Assessment (GAMA) Program Domestic-Supply (Shallow) Aquifer Assessment Study Unit Boundaries and Grid Cells for Assessment of Groundwater Resources (ver. 3.0, July 2025)
The California Groundwater Ambient Monitoring and Assessment Program (GAMA) is a statewide assessment of groundwater quality designed to help better understand and identify risks to groundwater resources. GAMA is implemented by the California State Water Resources Control Board. The U.S. Geological Survey (USGS) is the technical lead for the Priority Basin Project (PBP), one of the...
