Radionuclide and Pesticide data for sediment age and source analysis in the Midwest Stream-Quality Assessment Region (2013-2014)

A study examining the sources and ages of fine-grained bed material (<0.063 mm) was conducted for 99 sites in the USGS NAWQA Midwest Stream Quality Assessment (MSQA) during the summer of 2014, including 15 suspended sediment and 5 cropland top soil samples. Bed material samples were analyzed for radionuclides (7Be, 210Pbex, 137Cs) and pesticides (bifenthrin and DDE); s

Development of a Coastal Drought Index Using Salinity Data

A critical aspects of the uniqueness of coastal drought is the effects on salinity dynamics of creeks and rivers. The location of the freshwater-saltwater interface along the coast is an important factor in the ecological and socio-economic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including streamflow,...
