News Flash: MARGINS Discovery Student Presentations
Students describe MARGINS research results in a two to four minute oral class presentation. The assignment is appropriate for any class that covers topics related continental margins.

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.

From Ocean Topography to Flexural Rigidity
Students will use the available bathymetric datasets to test the utility of a flexural rigidity model of oceanic crust.

What Can (and Cannot) Be Learned from Scientific Drilling Using Examples from Margins Initiatives
This is a lecture segment that could be introduced to an introductory geoscience class to help explain and demonstrate what can and cannot be found out by scientific drilling.

Burial, compaction, and porosities in a subduction zone
In this activity, students look at how sediments compact as they are buried in a subduction zone and explore how rapid burial can lead to increased water pressure.

What Goes into Making Volcanic Arc Magmas, and How Do We Know It?
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.

NanTroSEIZE in 3-D
NanTroSEIZE 3-D is a online virtual voyage based on a seismic survey to study the plate boundary and seismogenic zone off Japan. The virtual voyage comes in two versions, one for use in lower division general education geoscience courses and the other in upper division geology courses in tectonics, marine geology and geophysics.

Fire and Ice: Identify and compare volcanic and glacial features on land and seafloor.
Bathymetry and topography are used to identify and compare glacial and volcanic features of the Sand Point area, Alaska.

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.
