Provides hydrologic instruments, equipment, and supplies for USGS, other Federal agencies, and cooperators. Also tests, evaluates, repairs, calibrates, and develops hydrologic equipment and instruments.
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.
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.
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.
We conduct systematic imaging of reef habitats in order to provide regulatory agencies with information they need to decide whether those reefs should be designated as protected 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.
Site to provide USGS scientists with web-based resoures to transfer new geophysical knowledge and experience; includes methods, tools, publications and training.
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.
Description and illustrations of hydroacoustic current meters for measuring the discharge in streams and rivers with links to wading discharge measurements, project progress and plans and references.
Technical information on acoustic methods of measuring water currents and applications of hydroacoustic techniques to problems in surface water hydrology.
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.
A network of tide gages and weather stations is deployed in coastal areas across the state to help forecast floods and support timely evacuation of people from affected areas.
Paper from Forum on Wildlife Telemetry, Snowmass Village, CO, 1997, describes technique for implanting radio-transmitters for tracking amphibians such as frogs with telemetry.
A valve failed in a research well, causing an uncontrolled eruption of steam and hot water. Video program shows technical problems encountered in controlling and capping the well.
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.
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.
