Unit 2: Examining the Distribution of Mass Wasting Events part of Planning for Failure: Landslide Analysis
What factors contribute to the distribution patterns of mass wasting events? In this unit, students will use a frequency-ratio method, one of the most common quantitative methods used in the statistical analysis of ...

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 ...

Unit 4: Groundwater, GPS, and Water Resources part of Measuring the Earth with GPS
GPS data can measure ground elevation change in response to the changing amount of groundwater in valleys and snow cover in mountains. In this module, students will learn how to read GPS data to interpret how the ...

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 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 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 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 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 2: Kilauea Hawai'i - Monday Morning Meeting at the USGS Hawai'i Volcano Observatory part of Monitoring Volcanoes and Communicating Risks
How do volcanologists at the Hawaiian Volcano Observatory monitor volcanoes? In a jigsaw format, students first work in teams to learn one of the four volcano monitoring data sets (GPS, Tilt, Seismic and InSAR) and ...

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 ...
