I just got back from Iranian side of the Persian Gulf-the
Asaluyeh/Nyband Bay region. Air temps 40, sea temps 35. (Email me
privately if you want comments on the joys of doing field work under
those conbditions.)

We observed corals at depths from 4-15m. No corals, at any depths, were
bleached. Gives perhaps some relevance to the term "resilience."

BTW, those mostly undescribed reefs had coral cover of approx
30%-higher than the Florida Keys.
