WHOI-engineered DISCO allows scientists to measure highly reactive superoxide on coral reefs

WHOI researchers successfully conceived and tested a portable device, DISCO, that performed the first in situ measurements of a highly reactive type of oxygen, known as superoxide, which may play an integral role in the health of coral reefs.

Researchers from Woods Hole Oceanographic Institution and the University of Washington tagged a group of five swords there to track their movements in and out of the ocean twilight zone, a dimly-lit layer of the ocean between 200 and 1000 meters deep (656 to 3,280 feet).
