GPS measurements track land uplift in northern Antarctica Peninsula and Amundsen Sea Embayment due to rapid ice sheet melting. The dataset supports a computer model, CitcomSVE, which simulates crust and mantle displacement using 3-D mantle viscosity and elastic properties. The project aims to interpret GPS data to constrain mantle viscosity and predict future land displacement.
Use Cases
- Model vertical land displacement from GPS observations using mantle viscosity parameters.
- Interpret GPS surface displacement measurements in the Amundsen Sea Embayment to constrain 3-D mantle viscosity.
- Predict future land displacement in Antarctica by simulating ice-melting induced deformation with the CitcomSVE model.
- Study the effects of transient and non-Newtonian mantle viscosity on crustal uplift rates from GPS data.
- Analyze the relationship between ice mass removal and gravitational attraction changes on sea level equipotential surfaces.
Strengths
- Focuses on two rapidly melting regions: northern Antarctica Peninsula and Amundsen Sea Embayment.
- Model incorporates realistic 3-D mantle viscosity and elastic properties, avoiding common depth-only assumptions.
Limitations
- Specific row count, column details, and sample data are unavailable.
- Geographic coverage is limited to specific regions of Antarctica.
- Dataset completeness and validation status are unknown.
