Chemicals of Emerging Concern in Water and Bottom Sediment in Great Lakes Areas of Concern, 2013 - Analytical Methods, Collection Methods, Environmental Data, and Quality Assurance Chemicals of Emerging Concern in Water and Bottom Sediment in Great Lakes Areas of Concern, 2013 - Analytical Methods, Collection Methods, Environmental Data, and Quality Assurance
The U.S. Geological Survey (USGS), in cooperation with the U.S. Fish and Wildlife Service (USFWS) and the U.S. Environmental Protection Agency (EPA), identified the occurrence of contaminants of emerging concern (CECs) in water and bottom sediment collected in 2013 at 57 sites throughout the Great Lakes Basin. The 2013 effort is part of a long-term study that began in 2010. Included in...

Spatial distribution of Rhodamine WT dye concentration measured in the Des Plaines River and the Chicago Sanitary and Ship Canal, Chicago, IL in November 2011 Spatial distribution of Rhodamine WT dye concentration measured in the Des Plaines River and the Chicago Sanitary and Ship Canal, Chicago, IL in November 2011
These data were collected during a dye tracing study of the lower Des Plaines River and lower Chicago Sanitary and Ship Canal (CSSC) in November 2011 by the U.S. Geological Survey. The study attempted to identify potential inflows of Des Plaines River water through the fractured bedrock that separates the two water bodies. Data include Rhodamine WT dye concentrations measured every 3 or...
2016 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes 2016 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes
A one-year seismic hazard forecast for the Central and Eastern United States (CEUS), based on induced and natural earthquakes, has been produced by the U.S. Geological Survey. The model assumes that earthquake rates calculated from several different time windows will remain relatively stationary and can be used to forecast earthquake hazard and damage intensity for the year 2016. This...
Water Quality and Hydrologic Data (2011-13) for Freshwater Science Paper titled, "Patterns of Diel Variation in Nitrate Concentrations in the Potomac River" Water Quality and Hydrologic Data (2011-13) for Freshwater Science Paper titled, "Patterns of Diel Variation in Nitrate Concentrations in the Potomac River"
This data set includes nitrate concentration, water temperature, and discharge collected every 15 minutes during Dec. 2011 - Nov. 2013 from the USGS gage at the Potomac River near Wash, DC, Little Falls Pump Sta (01646500). Additional data includes day length, and photosynthetically active radiation from USDA research station in Beltsville, MD. Several calculations derived from these...

Subscribe to Volcano Notification Services Subscribe to Volcano Notification Services
The Volcano Notification Service (VNS) is a free service that sends you notification emails about volcanic activity happening at U.S. monitored volcanoes. You can customize the VNS to deliver notifications for certain volcanoes or a range of volcanoes, and you can also choose the notification types you want to receive. Notifications are issued by the five U.S. Volcano Observatories.
