Interesting information about the FGB. The thing is that they're relatively
deep - min. 70-90' depth, which generally remains a little cooler than the
surface. Thus, 30oC at that depth may be just enough to push some of the
corals over the edge.
Secondly, the Hypoxic Zone occurs mainly to the east of Lake Sabine, TX and
more inshore. Plus it is a bottom phenomenon for the most part,
occasionally reaching close to the surface in more shallow waters. The FGB
are in 350' of water and at the edge of the continental shelf. I doubt the
Hypoxic Zone would be a problem there.

A nightmare indeed; condolences from all of us who treasure the Flower
Garden Bank reefs.
Although 86F (30C) isn't extravagently high, I think this is about the
annual warmest temperature on the banks and, if so, it might already be
above the seasonal average for mid-summer.
Lynton Land (my husband) immediately asked if the Gulf dead zone might have
impacted this area. Told him I'm pretty sure the banks are too far offshore
to be under its influence, but weather patterns over the continent have been
unusual this year, so maybe that's another straw at which to grasp..At least
a NOAA vessel should be tracking its movements around the Gulf this week
Please quickly clarify how to preserve affected tissues for metagenomic
analyses for Emma and her team.

run them, but as the situation clarifies, sequence and transcriptomic data
could be clinchers.
