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
Annika Johansson, Columbia University in the City of New York; Jeffrey Ryan, University of South Florida
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.
