Using geochemical proxies to trace sediment sources part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This is a series of lecture slides on how sediment geochemistry is used to obtain information about surface processes. The student is introduced to geochemical proxies, some applications, and is shown an example using strontium isotope distribution in the Bay of Bengal.
Tracing sediment provenance from source to sink: Isotope records in the Bay of Bengal and Indonesia part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
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.
