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 1: Exploring the Reservoirs and Pathways and Methods to Measure the Hydrologic Cycle part of Eyes on the Hydrosphere: Tracking Water Resources
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
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 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 2: Global Sea-Level Response to Temperature Changes: Temperature and Altimetry Data part of Understanding Our Changing Climate
What is the contribution of seawater thermal expansion to recent sea-level rise? In this unit, students create time-series graphs of global averaged sea surface temperature anomaly (SSTA) data spanning 1880–2017 ...

Unit 5: Societal Implications of Climate Change: Stakeholder Report part of Understanding Our Changing Climate
Sea-level rise due to the melting of glaciers and ice sheets and ocean thermal expansion has significant societal and economic consequences. In this final unit, students prepare a summary of the impacts of sea ...

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 2: Earthquakes, GPS, and Plate Movement part of Measuring the Earth with GPS
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 ...
