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 1: Collecting GPS Data part of Measuring the Earth with GPS
GPS data can measure vertical and horizontal bedrock motion caused by a variety of geologic processes, such as plate movement and the changing amount of water and ice on Earth's surface. In this unit, students ...

Virtual Geological Mapping Field Trip - Glens of Tekoa, New Zealand part of Teaching Activities
Geological mapping involves the observation, recording, presentation and interpretation of field data, all fundamental skills required by practicing geologists. This virtual geological mapping exercise enables ...

Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
The poles of the Earth's magnetic field are not precisely aligned with the geographic north and south poles and, in fact, vary continuously. This activity introduces to students the Earth's magnetic ...

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 4: Comparing risks at different volcanoes part of Monitoring Volcanoes and Communicating Risks
Students assess the risks from three different volcanoes based on the Risk Equation, Risk = Hazard x Value x Vulnerability. The three volcanoes--Fuego Guatemala, Rinjani Indonesia, and Moana Loa Hawaii--have ...

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 ...
