GAL - Geospatial Analysis Laboratory GAL - Geospatial Analysis Laboratory       The Geospatial Analysis Laboratory (GAL) has been established at the CRC to connect the Notre Dame community to Geographic Information Systems and Remote Sensing (GIS/RS) technology and resources. The GAL lab provides a geospatial computing environment, complete with full technical support and training, including an undergraduate/graduate course (ENVG 40810/60810 & GH 60810).
Student-accessible labs with the ArcGIS Software
"GIS" stands for Geographic Information System. GIS software represents features on the earth as digital, spatial data. GIS is used to visualize, question, analyze and understand digital geospatial data. Spatial analysis of GIS data can reveal patterns and highlight spatial connections and correlations not readily apparent. learn more ...
We are doing 3D hydrodynamic modeling of Lake Ontario to explore the thermal stratification of the lake and specially the formation of thermal bar. Thermal bar forms during summer turnover in Lake Ontario and affects nearshore water quality (cause eutrophication by algal bloom) and habitats of aquatic species. We are using hourly meterological and flow data from weather stations around Lake Ontario to simulate the formation and propagation of thermal bar. We will continue to do the simulation for progressive years and compare results to see the climatic impact on the thermal stratification in Lake Ontario. We intend to couple the hydrodynamic model Environmental Fluid Dynamics Code (EFDC) with a water quality model and/or hydrology model to analyze nearshore lake health in detail. Simulated results of the model will be validated using remotely sensed imagery from NOAA and NASA.
Upcoming Activities: Title: Modeling the Formation and Propagation of Thermal Bar in Lake Ontario Poster Presentation at Climate Change and the Common Good Conference April, 2013, University of Notre Dame, IN Title:Exploring Impact of Climate Change on the Formation of Thermal Bar in Lake Ontario
