Georgia Tech graduate student Doug Rasher is shown with a rack holding corals transplanted into concrete cones for experiments on reefs off the Fiji Islands.
The green seaweed Chlorodesmis fastigiati is shown growing on a reef. This seaweed damages the coral it contacts, as shown by the absence of corals immediately adjacent to it.
Photo shows an experimental coral that had been in contact with the green seaweed Chlorodemis. The white area of the coral is where contact with the seaweed has caused damage or death in the coral.
