Water Quality data from the Providence Water Supply Board for tributary streams to the Scituate Reservoir, water year 2015 Water Quality data from the Providence Water Supply Board for tributary streams to the Scituate Reservoir, water year 2015
Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 2014 through September 2015 (water year 2015). These data were used to calculate instantaneous loads and yields of constituents in a report by the U.S. Geological Survey. Water-quality samples were collected by the PWSB either monthly or...
Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts
Utilizing the USGS Meteor Crater Sample Collection, we sampled impact melt particles for geochemical and textural characterization using a scanning electron microscope and electron microprobe. Samples were collected from a range of different depths and distances from the crater rim, all within the proximal ejecta blanket. By using the Meteor Crater Sample Collection, in which all samples...
