Plan-view D. strigosa


You are viewing a plan-view animation traveling 'back in time' through the reef coral, Diploria strigosa. The movie represents passing down through the plan view of the coral for a distance of approximately 8 mm, or approximately 2 years of growth.

The 41 images which compose the animation are actually X-ray computed tomography (CT) scans of a sectioned coral cube, 25 mm on a side.

Corals are known to possess annual density bands that are similar to the annual growth rings in trees. It is interesting to note the structural thickening and thinning within the valleys (columella) associated with high density and low density periods of growth. Understanding structural changes associated with density banding aids in the study of corals as proxy records for environmental change.
