Advantages of Ocean Drilling

• Deep sea sediments and rock formations are less disturbed than on land.

• Each layer represents the environment at a specific time.

Hypothesis:

Coring in this region will enable us to determine the

timing and magnitude of sea level changes during the last

fifteen million years.

Why Here?

• The edge of this continent in this region is stable and not subjected to tectonic forces.

• The reefs are sensitive to sea level change because they are living and within a few meters of the sea surface.
