Unit 1: Exploring Harrier Meadow, an Urban Wetland System part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
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
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
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 2: Geophysical Properties of the Subsurface part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
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 5: Integrated Geophysical Interpretation and Comparison with Ground Truthing part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
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 3: Field Geophysical Measurements part of Evaluating the Health of an Urban Wetland Using Electrical Resistivity
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 2: What does GPR data look like? part of Forensic Geophysics Using Ground Penetrating Radar
GPR imaging is more complex than is portrayed in the media. This unit describes what the GPR response for a buried object looks like. This is a distorted image of the object itself. Nevertheless, the response we do ...

Unit 3: Case Studies and Limitations of GPR part of Forensic Geophysics Using Ground Penetrating Radar
This unit considers some ways to distinguish objects from each other while emphasizing the possibility of misinterpreting data. GPR imaging can be an excellent tool for detecting buried objects. However, as with ...
