Unit 1: Exploring Harrier Meadow, an Urban Wetland System part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
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: The Magic of Geophysical Inversion part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
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 1: Climate Change and Sea Level: Who Are the Stakeholders? part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
How are rising sea levels already influencing different regions? This unit offers case study examples for a coastal developing country (Bangladesh), a major coastal urban area (southern California), and an island ...

Unit 4: Groundwater, GPS, and Water Resources part of Measuring the Earth with GPS
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure ground elevation change in response to the changing amount of groundwater in valleys and snow cover in mountains. In this module, students will learn how to read GPS data to interpret how the ...

Unit 3: Field Geophysical Measurements part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
Near-surface geophysical measurements are performed by moving sensors across the earth's surface. Active geophysical sensors transmit a signal into the earth and record a returned signal that contains ...

Unit 1: Exploring the Reservoirs and Pathways and Methods to Measure the Hydrologic Cycle part of Eyes on the Hydrosphere: Tracking Water Resources
Jon Harvey (Fort Lewis College) and Becca Walker (Mt. San Antonio College)
How does water move throughout the Earth system? How do scientists measure the amount of water that moves through these pathways? This unit provides an alternative way for students to learn the major components of ...

Unit 2: Monitoring surface and groundwater supply in central and western US part of Eyes on the Hydrosphere: Tracking Water Resources
Jonathan Harvey (Fort Lewis College) and Becca Walker (Mt San Antonio College)
In Unit 2, students learn how the techniques for water budgeting (covered in Unit 1) can be used to monitor both groundwater (High Plains Aquifer) and surface water (western mountain watershed) systems. Students ...

Unit 5: Integrated Geophysical Interpretation and Comparison with Ground Truthing part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
In this unit, students explore spatial associations between the three-dimensional electromagnetic (EM) conductivity inversions and the visible patterns of Salicornia (pickleweed) introduced in Unit 1, Exploring ...

Unit 2: Geophysical Properties of the Subsurface part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
Archie (1950) defined the term petrophysics to describe the study of the physics of rocks, particularly with respect to the fluids they contain. Although originally focused on geophysical exploration, petrophysics ...

Unit 3: Monitoring groundwater storage with GPS vertical position part of Measuring Water Resources
Bruce Douglas, Indiana University-Bloomington; Eric Small, University of Colorado at Boulder
This unit shows how GPS records of surface elevation can be used to monitor groundwater changes. Students calculate secular trends in the GPS time series and then use the original and detrended records to identify ...
