Sediment Dispersal and Continental Margin Stratigraphy
This module examines different sediment dispersal systems and their relationships and controls on margin stratigraphy and geometry, using data sets from the Fly and Waipaoa river 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 ...

S2S Introduction: The Source-to-Sink Mini-Lesson Series
This module focuses on characterizing different river systems to better understand where sediment comes from and the variables that control sediment supply to continental margins in different tectonic settings.

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.

Source to Sink Morphology, Sedimentation, and Anthropogenic Impact: Hudson System, New York
Familiarize students with the morphology of passive continental margins and their associated shelf valleys, submarine canyons and estuaries, and assess the anthropogenic impact.

Using geochemical proxies to trace sediment sources
This lecture segments can be used in a mid- to upper-level course to introduce geochemical proxies commonly applied to weathering and sedimentation.

Sediment production and distribution across the margins
This activity is an exploration of the relationship among tectonics, sediment production, and sediment dispersal from watersheds to the continental margins. Students will examine data on a suite of watersheds and make measurements and observations in Google Earth or GeoMapApp.

Tracing sediment provenance from source to sink: Isotope records in the Bay of Bengal and Indonesia
In this exercise students examine data from a geochemical database to understand the link between source rocks and sedimentary deposits in the ocean, focusing on the Bay of Bengal in the context of the MARGINS Source-to-Sink initiative and contrasting these data with those offshore of Indonesia. This activity utilizes the online geochemical database SedDB, GeoMapAPP, and Excel.
