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 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 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: 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 1: Climate Change and Sea Level: Who Are the Stakeholders? part of Understanding Our Changing Climate
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 3: Global Sea-Level Response to Ice Mass Loss: GRACE and InSAR data part of Understanding Our Changing Climate
What is the contribution of melting ice sheets compared to other sources of sea-level rise? How much is the sea level projected to increase during the twenty-first century? In this unit, students will use Gravity ...

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: Measuring Ice Mass Changes: Vertical Bedrock GPS part of Understanding Our Changing Climate
This unit shows how GPS records of bedrock surface elevation may be used to monitor snow and ice loading/unloading on decadal and annual time scales. Students calculate secular trends in the GPS time series and ...
