RAMPS RestoreNet Sites

RestoreNet is a networked ecological experiment on the cutting-edge of restoration science. The experiment sites span dryland ecoystems of the southwest U.S.

GCMRC GIS Base Map Viewer 2.0

The Geospatial team of the Grand Canyon Monitoring and Research Center maintains an enterprise GIS system built upon ESRI ArcGIS Server and Portal applications.  This web application provides access to many of the most commonly used GIS layers and base data information used by GCMRC in support of on-going science projects.

Predicted Shorelines for High Flows on the Colorado River Application

This application highlights modeled flows of the Colorado River for a discharge of 41,000 cubic feet per second (cfs) that is approximate to recent (2012 - 2018) and future anticipated water releases associated with a High Flow Experiments conducted from Glen Canyon Dam near Page, Arizona.  These data are to help visualize the water levels during High Flow Events in relation to other map layers.

Sandbar Monitoring Sites - Remote Camera Photographs Application

GCMRC and Northern Arizona University have engaged in long-term monitoring of 45 sandbar sites along the Colorado River in Grand Canyon for close to three decades.  Remote cameras have been established to monitor sandbar changes in between site surveys that occur every Fall.   This application provides access to thousands of photos, with an option to view photos around specific high flow events.

Grand Canyon Map Portal

Grand Canyon Map Portal

Grand Canyon Poster Map (Low Res)

This is a low resolution poster map of the Grand Canyon region provided by the Grand Canyon Monitoring and Research Center (U.S. Geological Survey, Southwest Biological Science Center).  The poster map was exported from ESRI ArcGIS Desktop as a 36-inch by 24-inch output at 96 dots per inch (dpi).  This map is provided for general reference only and should be used for navigational purposes. 

Grand Canyon Poster Map (GCMRC)

The Grand Canyon Shaded Relief base map is provided by the Grand Canyon Monitoring and Research (Southwest Biological Science Center) as a resource for identifying and locating important places of interest along the Colorado River and across the Grand Canyon region.  

MODEL - Full Annual Cycle Bioenergetics Model of Migration Applied to Galapagos Tortoise

This code was created to run a bioenergetics-based model of movement for Galapagos tortoises. It calculates energetic surplus or deficit at a daily time scale based on inputted temperature (6 times a day) and NDVI value (a single value per days), as well as the mass of an individual. It then uses dynamic programming to determine the optimal timing of movement between two foraging habitats.

APPLICATION - Discharge, Sediment, and Water Quality Monitoring Application

This link launches the Grand Canyon Monitoring and Research Center’s discharge, sediment and water quality monitoring application gateway.  Sediment and water quality information can be accessed from here for our on-going monitoring taking place across the Southwest U.S.

APPLICATION - Grand Canyon Sandbar Monitoring

Several applications related to the Grand Canyon Monitoring and Research Center’s long-term sandbar monitoring project can be accessed here, including the sandbar area and volume tool and applications highlighting changes to sandbars as a result of High-Flow Events (HFEs) conducted by Glen Canyon Dam near Page, Arizona.

Grand Canyon Base Map Viewer

This web mapping application provides access to many of Grand Canyon Monitoring and Research Center’s most commonly used map layers in support of science efforts occurring throughout the Colorado River corridor.

APPLICATION - Grand Canyon Aquatic Ecology Web Application

This application allows for the exploration of a select set of insect emergence data collected as part of a citizen science project initiated by the Grand Canyon Monitoring and Research Center (GCMRC).  Data present in this application relate to a recent BioScience publication from USGS scientists and collaborators that investigated the effects of dam operations on downstream aquatic insects.
