Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
James Hensleigh is a Geographer for the Grand Canyon Monitoring and Research Center at the Southwest Biological Science Center. James earned his Bachelor of Science in Environmental Studies from University of Utah in 2008. James then spent one year from 2010 to 2011 studying Geo-ecosystem Dynamics at Universiteit van Amsterdam while also working as a Research Assistant and GIS Analyst for the Institute for Environmental Studies at Vrije Universiteit. In 2014 James completed his master's thesis "Geomorphic Change Detection using Multi-Beam SONAR" while obtaining a Master Of Science at Utah State University. The core of his thesis work is a synthesis of GIS and statistical analysis to develop an effective error model to quantify uncertainty involved in multi-beam SONAR surveys. From 2013 to 2016 James worked as a Geospatial Programmer/Analyst for the Ecogoemorphology & Topography Lab (ET-AL) at Utah State University. During that time his main focuses were programming for Geomorphic Change Detection software, CHaMP Topo Toolbar, and refining models of surface roughness for data obtained with multi-beam SONAR.
