Papua New Guinea (2008)

Papua New Guinea (2008)

The Papua New Guinea region is a MARGINS focus site for the Source to Sink initiative. The goal of the initiative is to develop a quantitative understanding of margin sediment dispersal systems and associated stratigraphy (sediment or rock strata formations).

New Zealand (2008)

New Zealand (2008)

The New Zealand region is a MARGINS focus site for the Source to Sink initiative. New Zealand is a major source of terrigenous sediment, supplying ~1% of the suspended load to the Earth's oceans.

Nankai (2008)

Nankai (2008)

This region including the southern islands of Japan, the Japan trench and the Nankai trough has been selected by MARGINS for focused study. Most of the world's great earthquakes and tsunamis initiate in the zone of underthrusting or seismogenic zone of subduction zones. The Seismogenic Zone Experiment (SEIZE) hopes to understand the relationship among earthquakes, deformation, and fluid flow in this environment.

Gulf of California (2008)

Gulf of California (2008)

The Gulf of California has been selected as one of two MARGINS focus sites for the study of rifting of continental lithosphere. The Gulf is particularly well suited to a large-scale study of rift processes, because it is actively rifting, contains clear rift segments that will enable reconstruction of the entire rift-drift history across unambiguous conjugate margins, has a reasonably well understood geologic and tectonic history, shows along-strike variations in extensional style, and is logistically accessible.
