Cause
of Coral Death
|
Black band disease kills coral tissue by exposing coral to a
toxic environment of sulfide and anoxia that is present at the
base of the band. These microenvironments can be measured
using microelectrodes. In these figures, the y axis represents
depth in mm into the band, with 0 representing the band
surface. Oxygen concentrations are designated as open
circles, sulfide as closed circles. The figures on the left
are profiles under varying light conditions (noted in the
figures); the figure on the right is after a prolonged period
of darkness. (From Carlton and Richardson, 1995)
