Instructor Materials: Overview of the Ice Mass and Sea Level Changes Module
- Students will interpret geodetic data to assess spatial patterns and causes of ice mass loss.
- Students will evaluate the impact of ice sheet mass change on global and regional sea level and consider societal implications of ice sheet mass and sea level changes.
The summative assessment asks students to apply their learning about ice mass and sea level changes related to Greenland to similar data sets from the Antarctic. It can be administered as high-stakes exam questions, a homework assignment after the module has been completed, or an in-class exercise at the end of the module.

The module covers material sequentially, but the units can also often be taught as stand-alone lessons. For instructors who do not wish to use the module in its entirety, suggested pairings are included in the "Context for Use" section on each unit's page.
This introductory exercise prompts students to consider a variety of consequences of sea level change on Bangladesh, whose population density and low-lying elevation make this developing nation particularly vulnerable to sea level rise.
In this unit, students use temperature and sea level time series to calculate global sea level and temperature trends since 1980, and they use these data to forecast global sea level for 2100. They also compare their results to 2100 global sea level projections and generate ideas for the causes of sea level change.
In this unit, students use 21st century Greenland temperature, ice elevation, ice velocity, and GRACE data to characterize spatial and temporal ice mass changes in Greenland. They also consider several mechanisms for ice mass changes using case studies of the Jakobshavn, Helheim, and Petermann glaciers.
In this unit, students use Greenland bedrock GPS and ice elevation data from 2000-2007 to investigate the concept of short- and long-term post-glacial rebound and the relative contributions of rebound and melting to sea level change.
In this unit, students compare sea level changes in different regions to decide whether sea level change is globally uniform, and they consider economic, social, and political consequences of future sea level changes on New York City and Southern California.
