Slab temperatures control melting in subduction zones, what controls slab temperature?
Hands-on demonstrations of advection and diffusion of heat in subduction zones, and their controls on slab thermal evolution and relationships to melting, using analog models.
Exploring Styles of Extension in the Gulf of California
An introduction to processes associated with continental rifting, and resulting fault geometries and distributions, and lithospheric responses, using seismic data examples from the Gulf of California.

Bathymetry of Rifted Margins
This is one component of the Rupturing Continental Lithosphere suite of mini-lessons. Students investigate the morphology of rifted margins by creating topographic/bathymetric maps and profiles across the Red Sea ...

Contemporary Climate Oscillations: ENSO and a case study of the Huanghe River
This module uses data of monthly mean sea level pressure from Tahiti and Darwin, Australia to calculate the Southern Oscillation Index (SOI) of El Niño-Southern Oscillation (ENSO) for comparison with the Huanghe River (China) discharge and correlated anthropogenic effects.
