We’re at the end of the high-alert coral bleaching season, and it looks like we’re dodging a bullet this year, at least as far as an expected severe bleaching of corals followed by mass die-off, as happened recently on the Great Barrier Reef in Australia.
The first dive was on Wednesday evening near shark o’clock so I did not go out that far — around 11-14 feet. It was kind of murky, and my wires were up.
Surface water temperature was 88 degrees.
The second set of freedives was at bright high noon on Friday with a maximum depth to 20 feet and sea surface temp was 84 degrees.
Practicing my dynamic breath-holding while diving under and staying as long as I can. Air is pretty remarkable.
According to NOAA and the Florida Department of Environmental Protection Coral Reef Conservation Program:
“Corals start to become stressed when sea surface temperature is 1 degrees Celsius greater than the highest monthly average. Coral bleaching risk increases if the temperature stays elevated for an extended period of time.”
Signs of paling (precursor to bleaching) and bleaching here, and some coral disease, which is a whole additional issue, but this year these corals should make it this year.
As of the end of September, the 2016 bleach watch threat has been downgraded to LOW.
But there is almost no way we can avoid rising sea temperatures in the coming years.
It’s like we’re holding our breath for the whole world.
I hate to piss in the ocean.
Waterlogged, dripping, I caught sight of myself in front of the bathroom mirror and stopped, face forward, shoulders square. wet-heavy clothes draining down my legs.
I just stared, listened.
The last of the summer heat baked outside, insects buzzing in all that peak green vegetation.
My dive boots were caked in damp sand. A puddle began forming on the concrete floor. The concrete was rough.
These white-painted wooden buildings up on stilts in natural parks from Florida to Texas always make me think of the Old South for some reason. On the outside anyway. But hey I don’t know shit about architecture.
