Unit 1: Collecting GPS Data
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 ...

Unit 2: Earthquakes, GPS, and Plate Movement
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 ...

Unit 4: Measuring Ice Mass Changes: Vertical Bedrock GPS
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 3: Global Sea-Level Response to Ice Mass Loss: GRACE and InSAR data
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 2: Monitoring surface and groundwater supply in central and western US
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 4: Groundwater, GPS, and Water Resources
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 3: Glaciers, GPS, and Sea Level Rise
GPS data can measure bedrock elevation change in response to the changing mass of glaciers. In this module, students will learn how to read GPS data to interpret how the mass of glaciers in Alaska and Greenland is ...

Unit 5: 2014 South Napa Earthquake and GPS strain
The 2014 South Napa earthquake was the first large earthquake (Mag 6) to occur within the Plate Boundary Observatory GPS network (now Network of the Americas- NOTA) since installation. It provides an excellent ...

Unit 4: GPS and infinitesimal strain analysis
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 ...

Unit 3: Getting started with GPS data
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 ...
