Quick look: Dissolved organic carbon (DOC) concentration and chromophoric dissolved organic matter (CDOM) parameters were measured over a range of discharge in 30 U.S. rivers, covering a diverse assortment of fluvial ecosystems in terms of watershed size and landscape drained. Relationships between CDOM absorption at a range of wavelengths (a254 , a350 , a440 ) and DOC in the 30 Dissolved organic carbon and chromophoric dissolved organic matter properties of rivers in the USA(Released: Thu, 13 Sep 2012 00:00 -0600)
Quick look: Many management agencies seek to evaluate temporal changes in aquatic assemblages at monitoring sites, but few have sites with ecological time series that are long enough for this purpose. Trends in aquatic-invertebrate and fish assemblage composition were assessed at 27 long-term monitoring sites in the north-central and northeastern United States. Temporal changes were identified using serial tr Temporal changes in aquatic-invertebrate and fish assemblages in streams of the North-central and Northeastern U.S.(Released: Thu, 13 Sep 2012 00:00 -0600)
Quick look: The U.S. Geological Survey, in cooperation with the U.S. Department of the Army Environmental and Natural Resources Management Office of the U.S. Army Signal Center and Fort Gordon, Georgia, assessed the groundwater, soil gas, and soil for contaminants at the Vietnam Armor Training Facility (VATF) at Fort Gordon, from October 2009 to September 2011.
