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.
Margin Morphology: Does Form Follow Function?
Students will use GeoMapApp to investigate variations in the geomorphology of continental margins both Passive and Active at various sites of the North American and South American continents. They will ...
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.
Chemical Inputs and Outputs at Subduction Zones
In this exercise students utilize data from geochemistry databases to analyze inputs and outputs associated with arc volcanism.
Are You in a Hotspot?
This activity is a PowerPoint module designed to help students differentiate hotspot island chains from volcanic island arc systems. Using map images, students are asked to describe and differentiate the topography and geologic features of the two tectonic settings.
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.
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.
