Sediments and carbon burial on the continental margins
This lesson explores factors that control the character and fate of carbon delivered by rivers from the continents to the oceans, using mapped characteristics and data from 12 different rivers, including the MARGINS Waipaoa and Fly systems.

Holocene Optimum: A time of massively increased sediment discharge for Asian Rivers
This is one component of the Source to Sink Mini Lesson Set This module is part of a larger set of mini-lessons that explores the variations in water and particulate mass flux from rivers that result from changing ...

From Source to Sink: How Sediment Reflects the Journey from the Mountains to the Sea
This is one component of the Source to Sink Mini Lesson Set Continental margins are phenomenal places to study the modern sedimentary cycle because sediment in margin regions has been routed from mountains ...

Central American Arc Volcanoes, Petrology, and Geochemistry
This module teaches basic concepts in igneous petrology through relating hand specimen identification of lavas to major element geochemistry, using the Central American volcanic arc as an example.
