Travis William Nauman, PhD, Soil ScientistMy Professional Interests![]() I recently finished a PhD at West Virginia University, and moved back west to work for the USGS in Moab, UT. I've been focused on improving soil mapping products and integrating them with land management frameworks. In particular, I am working on development of ecological site descriptions in a variety of ecosystems. This work has varied from looking at shifts and carbon implications of the regional transition between northern hardwood and subalpine conifer forests in the Appalachians from railroad era disturbance (Nauman et al., 2015) to assessing dust emissions from disturbed drylands in the western US. Current projects include the Automated Reference Toolset (ART), oil and gas well-pad rehabilitation, dust monitoring, LandPKS mobile application development, digital soil mapping of next generation soil surveys, and ecological site development. Undergraduate Studies: 2002-2006 (University of Arizona) Worked at Water Quality Lab where I Iearned a lot of the basics of soil and water analysis. Soil Judging, an academic competition in field soil characterization, was a favorite undergraduate experience. National Soil Judging competitions in Illinois and Alabama proved to be some of my most memorable college experiences. I had the privilege of working on the Audubon Research Ranch as an intern. There, in addition to some grunt-work, I received the Audubon Apacheria Research Fellowship for research entitled: 'Soil Properties in Sacaton (Sporobolus wrightii) Restoration'. This research ended up lasting about a year and produced a report helping to aid future efforts of restoring Sacaton, a native Arizona riparian long-grass that was almost lost during the 20th century. Sonoran Institute: 2006-2009 After completing undergraduate work, the Sonoran Institute took me on as a Research Assistant in June of 2006 to help work with the Sonoran Desert Network (SODN) division of the National Park Service Inventory and Monitoring Program. Nauman Geospatial: 2009-2011 I worked on and off as an independent consultant. I have worked on a variety of natural resource and soil science projects. USDA - Natural Resources Conservation Service 2010-2011 I have worked in various capacities with the NRCS in soil mapping and ecological site description applications. Graduate Work, 2007-2009 (University of Arizona); 2011-2015 (West Virginia University) My graduate work has focused on improving soil inventory maps for use in land management. My work at the University of Arizona with Dr. Craig Rasmussen focused on evaluating ASTER satellite imagery and USGS Digital Elevation Models for soil mapping. At West Virginia University, I helped update regional soil survey and developed some of the first forest ecological sites in the eastern USA. US Geological Survey: 6/2015 - Present Projects at the USGS include digital soil mapping, erosion modeling, dust emission modeling, oil and gas reclamation monitoring, salinity loading, ecological restoration, ecological site development, and field soil science training.
