Unit 5: Societal Implications of Climate Change: Stakeholder Report
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 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 ...

Geoid Height Calculator
The Geoid Height Calculator returns the geoid height at the latitude and longitude specified by the user. The geoid is one approximation of Earth's shape due to gravity, roughly coinciding with mean sea level. Because the inside of our planet is non-uniform, gravity is not constant at the surface. If Earth were completely covered in an ocean, the water would swell over gravity highs (where there is more mass below the surface) and depress in areas of gravity lows (where there is less mass below the surface). The geoid approximates this hypothetical ocean surface, representing a geopotential surface. To think of it another way, if we were able to walk on the geoid, we would experience a constant value of gravity.
