A program of studies with instruments to provide accurate and timely data and information on seismic events, including their effects on buildings and structures, employing modern monitoring methods and technologies.
To better understand the exchange of groundwater and surface water, we coupled groundwater monitoring at the stream bank with nearby gages in the stream. Describes the procedure and results from several areas.
Papers from Forum on Wildlife Telemetry, Snowmass Village, CO, 1997 about innovations in transmitting and receiving systems, attachment techniques, collection of data using telemetry, data processing and analysis. Available as *.zip file to download.
Proxy methods allow us to estimate ancient ocean temperatures but only if the method is calibrated using modern samples for which we measure the temperature. This is a proxy method using a sediment trap to collect planktonic foraminifera.
We put seismic monitoring instruments into 20 VA hospital buildings, connected with computers that analyze their data to determine rapidly the structural health of the buildings in the event of earthquakes.
Provides hydrologic instruments, equipment, and supplies for USGS, other Federal agencies, and cooperators. Also tests, evaluates, repairs, calibrates, and develops hydrologic equipment and instruments.
Instructions on how to build a protective outdoor seismic vault used as stations for broadband seismic sensors that respond to seismic energy, temperature, and atmospheric pressure for the United States National Seismic Network in PDF format.
Specialized monitoring systems installed in a VA hospital in Memphis, TN will help us to design safer hospitals and other buildings and to prevent loss of life in this and similar earthquake-prone areas.
The Sediment Transport Instrumentation Facility at USGS Woods Hole Field Center maintains and deploys oceanographic instrumentation for the study of coastal and ocean circulation and sediment transport.
The Technology Enterprise Office provides a link between research teams within USGS and private sector individuals or organizations interested in access to USGS technology through patent licensing, CRADAs or other cooperative arrangements.
Instrument measures elemental abundance and isotopic ratios in samples as small as a few nanograms. Uses include geochronology, geological thermometry, and trace element geochemistry of geological and biological materials.
USGS operates a low-enriched uranium-fueled, pool-type reactor located at the Denver Federal Center. We use it for analyses of fissile and fissionable isotopes, geochemical analysis, and geochronology.
Monitoring soil temperature, soil moisture, air temperature, and overall thickness of the soil and sediment that is above the permafrost, therefore undergoing freeze-thaw cycles. Climate change may affect this active layer; we want to know how it does.
It is important that we collect samples consistently and properly to assure the quality of the information needed by decision makers. This report explains the procedures for sampling water, sediment, benthic invertebrates, and microorganisms.
Usually we choose to put water monitoring stations in places where we have no data already. But it's more efficient to place stations so that they help to reduce uncertainty in the results of modeling. This analysis shows how to choose.
