Thomas M Gushue

Thomas Gushue is currently the Geographic Information Systems (GIS) Coordinator for the U.S. Geological Survey’s Grand Canyon Monitoring and Research Center (GCMRC), a group assigned to studying the impacts of the Glen Canyon Dam on the downstream resources of the Colorado River corridor. 

In this capacity, Tom leads GCMRC's Geospatial Science and Technology project that provides expertise and support to the Center in database and geospatial data management, geospatial analysis, enterprise GIS administration, and development of tools and applications for accessing geospatial data online.

Established to meet the mandates of the Grand Canyon Protection Act of 1992, the GCMRC conducts a variety of studies related to long-term monitoring of the cultural and natural resources of this unique canyon environment.  At the heart of much of this work is the GIS platform that provides a consistent spatial reference system for overlay and analyzing the wealth of data collected as part of the GCMRC’s mission.  As GIS Coordinator, Tom is involved with monitoring and research efforts that have spatial aspects associated with them.

Modernizing sensor data workflows to leverage Internet of Things (IoT) and cloud-based technologies

Drought is a major problem in the American Southwest that is expected to worsen under the effects of climate change. Currently, the Southwest Biological Science Center is monitoring the effects of drought with soil moisture probes in a range of ecosystems across an elevational gradient on the Colorado Plateau. These data are used in multiple studies to analyze the effects of drought on vegetation

Gross primary production estimates and associated light, sediment, and water quality data from the Colorado River below Glen Canyon Dam

These data were compiled to model the effects of flow regime and bed grain size distributions on rates of gross primary production (GPP) in the Colorado River below Glen Canyon Dam, AZ, USA. The objectives of our study were to quantify daily and weekly scale effects of an experimental flow regime on GPP in the Colorado River. The experimental flow was conducted at Glen Canyon Dam from May-August i
