Volcano Expedition to the Mariana Islands:
The Ins and Outs of how Earth Works
Anatahan Erupts May, 2003
A team of researchers taking part in the National
Science Foundation MARGINS initiative traveled to the Mariana
Islands at the western edge of the Pacific Ocean to answer some of the
most challenging questions of plate tectonics. They seek a better understanding
of subduction zones where material is routed from Earth's surface to its
interior. What they find might also reveal how the atmosphere that sustains
life on Earth was created and how it continues to evolve. This Web site
will take you to nine volcanic islands in the chain, offering a guided
tour through photos, video and day-by-day accounts of what the research
team found. Along the way, get to know the history of the Mariana Islands.
Now a commonwealth of the United States, the Marianas' story is one of
occupation by a succession of different peoples and includes a pivotal
role as the site of history-making events during World War II.
Of all the movies and pictures shot during the expedition, this one is our favorite. If you don't look at
anything else, check out this video!
