Unit 4: The Magic of Geophysical Inversion part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Lee Slater, Rutgers University-Newark
This unit introduces the student to the concept of geophysical inversion, which is the process of estimating the geophysical properties of the subsurface from the geophysical observations. The basic mechanics of ...

Unit 3: Codorus Creek Case Study: Measuring and Interpreting Seismic Refraction Data part of Measuring Depth to Bedrock Using Seismic Refraction
Andrew Parsekian, University of Wyoming
This unit presents an applied case study example and the associated concepts related to designing a seismic survey and analyzing the data. It discusses parts of the instrument and presents practical experience ...

Unit 1: Exploring Harrier Meadow, an Urban Wetland System part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Lee Slater, Rutgers University-Newark
Students will conduct a virtual exploration of Harrier Meadow, a salt marsh in the New Jersey Meadowlands. They will identify its vulnerability to pollution, its tidal connection to the Hackensack Estuary and the ...

Unit 4: Analyze and Prescribe a Risk Assessment and Hazard Mitigation Plan part of Planning for Failure: Landslide Analysis
Stephen Hughes, University of Puerto Rico-Mayaguez
How can community stakeholders use the landslide susceptibility model to inform planning and infrastructure decisions? Students will create a landslide risk analysis report and assessment plan for a specific ...

Unit 4: Measuring Ice Mass Changes: Vertical Bedrock GPS part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
This unit shows how GPS records of bedrock surface elevation may be used to monitor snow and ice loading/unloading on decadal and annual time scales. Students calculate secular trends in the GPS time series and ...

Unit 2: Earthquakes, GPS, and Plate Movement part of Measuring the Earth with GPS
Karen Kortz, Community College of Rhode Island
GPS data can measure bedrock motion in response to deformation of the ground near plate boundaries because of plate tectonics. In this module, students will learn how to read GPS data to interpret how the bedrock ...

Measuring the Earth with GPS: Plate Motion and Changing Ice-Water part of Measuring the Earth with GPS
Measuring the Earth with GPS: Plate Motion and Changing Ice-Water Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College) Editor: Beth Pratt-Sitaula (EarthScope Consortium) Initial Publication Date: May 28, 2019 DOIThis page currently has no DOI, but you may request a DOI be assigned. | Cite thisGETSI. (2019, May 28). Measuring the Earth with GPS: Plate Motion and Changing Ice-Water. https://serc.carleton.edu/getsi/teaching_materials/measure_earth/index.html
Although GPS's first widespread use by geoscientists was to track plate motions, geoscientists have found that GPS can also be used to measure local movement due to changes in the amount of water, snow, and ...

Unit 1: Monitoring Volcanic Activity at Mount St. Helens part of Monitoring Volcanoes and Communicating Risks
Rachel Teasdale, California State University-Chico; Kaatje van der Hoeven Kraft, Whatcom Community College
How can data from an impending volcanic dome-building event be used to forecast the hazard to a surrounding community? In this activity, students will examine geodetic data (GPS and lidar) and seismic data in a ...

Unit 2: Kinematic GPS/GNSS Methods part of High Precision Positioning with Static and Kinematic GPS
Ben Crosby, Idaho State University
The application of Global Navigation Satellite Systems (GNSS) in the earth sciences has become commonplace. GNSS data can be collected rapidly and compared in common reference frames. Real-time kinematic (RTK) GNSS ...

Unit 3: Static GPS/GNSS Methods part of High Precision Positioning with Static and Kinematic GPS
Ben Crosby, Idaho State University
The application of Global Navigation Satellite Systems (GNSS) in the earth sciences has become commonplace. GNSS data can produce high-accuracy, high-resolution measurements in common reference frames. Static GNSS ...
