Digital Elevation Model Created by an Unmanned Aerial System
Digital Elevation Model Created by an Unmanned Aerial SystemThis digital elevation model was created using structure from motion software mounted to an Unmanned Aerial System (UAS) to analyze bridge scour. Studies using UAS have included stream temperature analyses, bird and mammal surveys, coastal change mapping, sandbar habitat surveys, fluvial erosion rates, microclimate mapping, air quality analysis, plant stress as

Groundwater Sampling at Mt. Hope Cemetery, Michigan
Groundwater Sampling at Mt. Hope Cemetery, MichiganIs this cemetery haunted? Probably not, but there could be tiny things moving beyond the grave. The USGS sampled groundwater downhill of Mt. Hope Cemetery in Lansing, Michigan, to find out if materials associated with decomposition and burial processes could affect groundwater quality near a cemetery.
