Margin Morphology: Does Form Follow Function?
Students will use GeoMapApp to investigate variations in the geomorphology of continental margins â both Passive and Active â 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.
A tour of the Mariana Subduction System
This lesson presents a brief tour of the Mariana subduction system, an active continental margin in the west Pacific.
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.
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.
Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc
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.
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.
