We have had a busy few days (hence the lack of updates). During this time, we've hit our stride and optimized the instrumentation for making in situ superoxide measurements. Despite a few hiccups here and there, we have had remarkable success in making these measurements! The data are better than we had expected or even hoped for! We have measured superoxide concentrations from both bleached and pigmented colonies of five different coral species, Porites compressa, Porites lobata, Montipora capitata, Pocillopora damicornis, and Fungia scutaria, from five different reefs. The depth of corals has ranged from less than a foot to up to 5 feet. We have a lot of data modeling ahead of us!

An assortment of coral species included in our analysis. Species shown here include P. compressa (top left), F. scutaria (center), and a bleached M. capitata (bottom center).

The majority of the M. capitata colonies that we have seen are severely bleached, as illustrated by the colony to the left.
