The Grand Canyon Monitoring and Research Center maintains an enterprise GIS platform built upon ESRI ArcGIS Server and Portal applications. This enterprise system allows for spatial data, maps and analytical tools to be served through online applications. The Geospatial Science and Technology project provides access to this content through different avenues. Online maps can be accessed through...

The Grand Canyon Monitoring and Research Center develops and collaborates with other science centers to create online data applications that provide access to project data as it becomes available to the public. Some of these applications provide data in near real-time, while other project data are updated at some regular interval (annually, quarterly). Content listed here include applications that...

The Grand Canyon Monitoring and Research Center offers a collection of data resources and online tools -- including web maps, applications, and other content -- that convey scientific information related to on-going monitoring of the Colorado River. Some applications are a culmination of long-term monitoring work, while others are developed around more a specific set of information usually derived...

All aquatic invertebrates drift downstream at some point in their life cycle. Invertebrates may drift to find more preferable habitats, to leave the water during their transition from aquatic larvae to terrestrial adults, or accidentally such as when swept off the riverbed by a flood. Regardless, when they enter the drift, invertebrates become particularly susceptible to predation by several...

Aquatic insects live in the water as larvae most of their lives, then emerge onto land for a brief period as winged adults. Sampling these emerged adults on land is therefore a useful tool for understanding the condition of the aquatic insect population that is in the water, particularly in large rivers where sampling the larvae on the river bed is impractical. Our group uses a variety of methods...
