A most valient effort as usual but I do have some questions.
1) The fastest growth does require some pretty specific conditions which I
could grant you might have existed at some point in the past, say for a
short time post-flood. But could these conditions have been sustained
such that the optimal growth could continue for the entire period. If
growth was suboptimal at any time then the estimated time of growth must be
2) Expanding on #1 what about evidence that the reefs were at different
points in time subariel. How would this fit into a Flood or post-Flood
scenario? It would appear (from wht I have been told!) that for the
coral to change composition in the subariel state would take some time.
Further there is the question of the reason for their being lifted out of
the water in the first place. I presume that this would explained even by
global flood advocates as being a result of a drop in the ocean level not a
rising of the now extinct volcano below. According to the predominant
YEC model (not necessarily yours) maybe an ice age following the Flood
resulted in the lowering of the oceans but as I read the data the evidence
of subariel coral is rather high up on the total column indicating a rather
recent dramitic fluctuation in sea level that if we read the coral column
as growing at maximum rate since the flood must have occurred in the last
3) There is the matter of when the volcano was created. Most would likely
say during or after the flood (a la Walter Brown) and thus the reef would
have its origins at some point after the Flood. Also I am going to guess
here that the basalt drilled into at the top of the volcano showed evidence
of having been extruded in atmospheric conditions much like the Hawaiian
seamounts (correct me if I am wrong here, or anywhere else for that
matter). If this is the case it would be interesting to see how far
above the surface the volcano was at one time. If it had any sifnificant
height then we also have to allow for its sinking back into the ocean
before the coral could begin to accumulate on its top.
4) Regarding the sinking of the volcano itslef. It seems that in order
for this coral reef to have built to its present stage the combination of
the ocean levels and sinking of the volcano could not have fluctuated
dramatically or it wouldn't have happened. The volcano we must almost
assume must have been sinking at a fairly constant rate (ie. at what
happens to be the maximum growth rate of the coral). Further the volcano
isn't sinking at that rate presently so we need some mechanism for it
sudden slowing in its rate of sinking as well as a sudden slowing of the
growth of the coral (which I could see as being correlated with that slow
down in sinking). In Walter Brown's flood scebario after the separating
of the continents during/causing the flood we have the seamounts rapidly
rising from the sea floor and because the sea floor is also quite warm
still it is warped up. As the sea floor cooled it rapidly fell at first
lowering the sea levels (but notice that the seamounts would also be
lowering at a similar rate) then has gradually been slowing in its pace to
a point today where it is very slowly sinking and the plates are still
moving very slowly just as they are measured.
Just some random thoughts.
I have a discussion of the same problems and events in life of the Hawaiian
