What Goes into Making Volcanic Arc Magmas, and How Do We Know It? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a directed reading exercise focused on papers that have been key to our understanding of the major source contributors to subduction zone volcanic rocks.

Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a Web investigation and research exercise starting with the 2003-present Anatahan volcanic eruptions in the Mariana arc, and concluding with a petrologic examination of published Mariana arc lavas data sets.

Serpentinite in Subduction Zones: How do we find it, and how common is it? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
A mineralogical, petrological, and geophysical exploration of the role of serpentinite in subduction zones, as highlighted in the two NSF-MARGINS Subduction Factory focus sites.

Chemical Inputs and Outputs at Subduction Zones part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Karin A. Block, CUNY City College
In this exercise students utilize data from geochemistry databases to analyze inputs and outputs associated with arc volcanism.

Using geochemical proxies to trace sediment sources part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Karin A. Block, CUNY City College; Annika Johansson, Columbia University in the City of New York
This lecture segments can be used in a mid- to upper-level course to introduce geochemical proxies commonly applied to weathering and sedimentation.

The Woodlark Basin as a Natural Laboratory for the Study of the Geological Sciences part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Andrew Goodliffe, The University of Alabama
This activity guides the students through a set of geological problems related to the Woodlark Basin, Papua New Guinea.

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.
