[Coral-List] Reassessing Coral Reef Scientists

Hi Doug:

I didn't want to just go dark, but it's the time of year when student
theses, end-of-year chair duties and all those other fun parts of academia
get superimposed. So, I'll have to get back to you when I'm out of the
weeds.Actually, Lucien and a few of us have been discussing this quite a
lot over the past 18 months. The one outlier that we weren't aware of is
the new Topex-Poseidon data show that sea level is rising at very different
rates in different places for reasons having nothing to do with subsidence,
tectonics or the usual cast of characters for regional differences in SL
rise on a scale of centuries to millennia. Near Australia, it's going up at
ca 10 mm/yr while in other places it is actually dropping. What seems to be
emerging is a relationship with ENSO like cycles that operate over scales
of decades to perhaps 60 years. Obviously, sea level can't continue to rise
at these differential rates indefinitely or else we're going to see people
water skiing without boats from Australia to the US on the resulting
water-surface slope.

So..... if these areas of "winners" and :losers" are ephemeral and operate
on time scales of several decades, that's going to mean that all those new
corals on GBR reef flats (IF SL rise does encourage coral recruitment or
survival) are going to get whacked when SL starts dropping on the GBR and
rising across the pond. I don't claim to understand the dynamics, but it
seems inescapable that what goes up must come down - and if there are
places where SL is rising faster (and presumably there are fewer low tides)
over the next two decades, they are in for a big disappointment down the
line. I'm hoping that somewhere the modelers can give us a
back-of-the-envelope calculation on the periodicity and amplitude of these
excursions. In the meantime, it seems like trying to extrapolate from what
we're seeing on a decadal scale to even a few centuries ignore the
likelihood that the variability is going to totally swamp the success rate
in the longer run. So, unless we're going to open a market for "coral
futures", these short-term patterns are not going to be helpful. I can't
even begin to predict what the magnitude of these might be, but from what
little I've read these patterns we're just beginning to see may end up
being the critical piece of the puzzle.

I wish I had a better answer,

Dennis
