Quantifying Nutrient Mass and Internal Cycling in Great Salt Lake
The Great Salt Lake (GSL) is an indispensable economic and ecological resource. It provides critical habitat and food for millions of migratory birds, and generates nearly $200 million per year from recreational activities and the brine shrimp harvest industry (Bioeconomics, 2012). These uses, habitat and aquaculture, rely on a balanced supply of nutrients in the Great Salt Lake to support...
Auroras and Earthquakes: Strange Companions
In 1722 and 1723 a London clockmaker, George Graham, observed daily and consistent variations on one of his instruments, a “Needle upon the Pin” (a compass), for which he had no explanation. Swedish scientists obtained some of Graham’s instruments to record what is now known to be the variations in Earth’s magnetic field. In 1741, they noticed a significant deflection of the compass needle...
Rossfelder vibracorer
USGS uses the vibracorer is best in locations where the seafloor, lakebed, bay-floor, or river-bottom sediment is unconsolidated and waterlogged.
Hydrogeological Evaluation of the Edwards Air Force Base Air Force Research Laboratory Area and the North Muroc Groundwater Subbasin, Antelope Valley, California
In cooperation with Air Force Civil Engineer Center (AFCEC), the U.S. Geological Survey (USGS) is evaluating the hydrogeology of the Air Force Research Laboratory (AFRL) and Site 25 areas of Edwards Air Force Base (EAFB) and the adjacent North-Muroc groundwater subbasin to help determine regional groundwater movement and the possible long-term movement and pathways of contaminated...
Tracking Data Releases
U.S. Geological Survey, Alaska Science Center, has previously released tracking data sets of polar bears, walrus, and Greater White-fronted goose.
Eyes on Earth Episode 28 – Peer Reviews
Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we learn how remote sensing bolstered its credibility through the strength of rigorous peer...
MD-DE-DC WSC Water Use & Water Supply Capabilities
In Maryland, public supply water is delivered to users for domestic, commercial, and industrial purposes. Most is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and some is unaccounted for because of leaks, flushing, tower maintenance, and other system losses. 5.7 million Marylanders get their water from the public...
MD-DE-DC WSC Geomorphology and Sediment Studies Capabilities
Geomorphology is classified as the study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Adding water creates a whole new dynamic known as Fluvial Morphology. Rivers and streams act as conduits of water along with sediment. As water flows over the channel bed, it is able to...
MD-DE-DC WSC Modeling Capabilities
USGS models are widely used to predict responses of hydrologic systems to changing stresses, such as increases in precipitation or ground-water pumping rates, as well as to predict the fate and movement of solutes and contaminants in water.
The USGS is at the forefront of devising new techniques and computer software to solve practical problems in the study of water resources....
Tracking Data for Three Large-bodied Gull Species and Hybrids (Larus spp.)
Available here are tracking data of large-bodied gull species and hybrids (Larus species). These data were collected to better understand the migratory movements of these birds and their role in the dispersal of antibiotic resistant bacteria among areas of Alaska and other regions.
Hazards: EXPRESS
Marine geohazards including earthquakes, landslides, and tsunamis lie offshore of densely populated areas of California, Oregon, and Washington. One goal of EXPRESS is to improve assessments of these hazards.
Resources: EXPRESS
Along the U.S. west coast, the Pacific Ocean, ocean floor, and winds above contain potentially vast energy and mineral resources. Developing these resources safely and wisely requires detailed information for each area of interest. One goal of EXPRESS is to inform ocean...
