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 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 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 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 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 3: Getting started with GPS data part of GPS, Strain, and Earthquakes
This unit provides essential background information on GPS (global positioning system) and reference frames. Students learn how to access GPS location and velocity data from the Network of the Americas (NOTA). They ...

Unit 2: Mashing it up: physical models of deformation and strain part of GPS, Strain, and Earthquakes
Students gain an intuitive understanding of strain and deformation through a series of physical model activities using everyday materials such as bungee cords, rubber bands, fabric, index cards, silly putty, sand, ...

Unit 6: Applying GPS strain and earthquake hazard analyses to different regions part of GPS, Strain, and Earthquakes
Students select their own set of three stations in an area of interest to them, conduct a strain analysis of the area between the stations, and tie the findings to regional tectonics and societal impacts in a 5–7 ...

Unit 4: GPS and infinitesimal strain analysis part of GPS, Strain, and Earthquakes
Students work with GPS velocity data from three stations in the same region that form an acute triangle. By investigating how the ellipse inscribed within this triangle deforms, students learn about strain, strain ...
