“Natural Gas in The Continental Margins” with Jeffrey Weissel (Mar 2003)

by admin | Jul 21, 2023 | Continent-Ocean Margins

Originally present Mar 2003

Introduction to Natural Gas and Continental Margins

Dr. Michael J. Passow

What are the real boundaries of continents and oceans? Why are they different in various parts of the world? How did they form? These are some of the concepts addressed in this introduction to the Workshop. Also, Dr. Weissel’s investigations explore the occurrence of natural gas (methane) within continental margin sediments, a significant area of current research and potential hazard.

Earth Science Content

We’ll begin with a review of our historical understanding of the ocean floors, going back to M. F. Maury’s famous “Physical Geography of the Sea” and continuing through early sonar studies and the Heezen-Tharp maps to modern seismic surveying and other geophysical techniques. We will view a special DVD about ODP Leg 204 and the launching of the new drilling ship, Chiku. Then we’ll focus on the Atlantic coast of North America, and especially the region off the Southeast where methane and gas hydrates exist within sediments. This sets the basis for our guest scientist, Jeffrey Weissel, to describe more about about the potential impact of these materials on energy supplies, climate change, and hazards, such as tsunamis from offshore slumps.

Integrating Educational Technologies

Online Projects that you can join:

One good strategy for teaching with the Internet is to join a project that is already organized. There are several ongoing projects that allow teachers and students to interact with specialists from all of the world, share information with each other, and participate in real research. Below are some links to projects. Feel free to explore and if you have any projects you would like to share or if you would like to invite other teachers to a project you are doing with your students, go to the Mentoring section and fill in the form! We’ll be glad to help you!
