I can't get that page to come up for some reason. Found it at Google and still can't get it to open. Another reference on the subject refers to creationist Snelling saying that conditions of the Flood would have caused the coccoliths to "bloom," which is an explanation I've run across before, but what those conditions were wasn't part of that article.
Perhaps I'm just impatient but my computer is very slow these days and I'm back here to ask you if it's easy enough to put the idea into words yourself. Or maybe give me another link I can actually open. Thanks. But meanwhile I can go on speculating. Creatures could be expected to proliferate under ideal conditions so I'd speculate that perhaps those conditions were ideal for coccoliths in the pre-Flood era, when creationists usually suppose a much more fecund world in general anyway. One thing that is often hypothesized is shallower warmer ocean water. Would coccoliths like that? Maybe also the conditions during the Flood were also advantageous as Snelling proposes but I don't have a guess as to what he thinks those conditions are supposed to have been. As for the problem with transporting existing coccoliths that you expressed, because they would have been hardened into rock as they are in the cliffs, I keep seeing them described as "calcareous ooze" which doesn't sound like rock.

It's not opening for me either atm, it looks like their server isn't responding. it's too long and fanciful for me to reproduce it, we'll just have to wait.

You've seen the picture of the cliffs, does it look like ooze to you? Clue, my house is built on it. Or are you saying that the ooze only hardened in the 4,000 years after the flood?Life, don't talk to me about life - Marvin the Paranoid Android

Coccoliths bloom in real life, it doesn't produce the amount of sediment required. Though it is pretty.
Would coccoliths like that? Well the problem, as I've explained, is that they need sunlight. This places an upper limit on the number of coccolithophores you can have at one time, because once the surface is covered with coccolithophores, you can't have any more coccolithophores under that, because they'd be in the shadow of the coccolithophores on top. So the "ideal conditions" for coccolithophores is not having too many coccolithophores.
As for the problem with transporting existing coccoliths that you expressed, because they would have been hardened into rock as they are in the cliffs, I keep seeing them described as "calcareous ooze" which doesn't sound like rock. They start off as calcareous ooze, which lithifies by compaction and recrystallization. Edited by Dr Adequate, : No reason given.

And anyway, pretty much all schools now use whiteboards with marker pens.
I have the good fortune to be teaching in what I call a "smart classroom". It has real blackboards, instead of those awful whiteboards.
Pity really, I suspect having a teacher throw a marker pen at you will cause more damage than chalk.

No, I'm not suggesting that chalk of the hardness of the cliffs could have been transported. I'm considering that perhaps where they collect at the bottom of the ocean that they are in that condition of "ooze" and might be transportable. Can you answer THAT thought?
Never mind, I think Dr. A did and it suggests that yes, they may have been in a transportable condition at the time of the Flood or some great number might have been. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

The amount of sunlight available should depend on the size of the area they cover. What area of sea floor would they need to cover to produce an amount that could build the chalk cliffs or all the chalk formations on earth?

What area of sea floor would they need to cover to produce an amount that could build the chalk cliffs The point is, they would be dead on the sea floor. They have to be on the surface layers of the sea where there is enough light for photosynthesis while they are alive, during a bloom. When they die they slowly sink to the bottom and over time build up into thicker and thicker layers that are solidifying at the bottom.
I'm considering that perhaps where they collect at the bottom of the ocean that they are in that condition of "ooze" and might be transportable. It probably would be transportable if there were currents there at the bottom of the ocean. How would the ocean level getting deeper because of "the flood" create currents, at the bottom of the ocean, that would move the primordial ooze some place else and solidify it once it got there?What if Eleanor Roosevelt had wings? -- Monty Python One important characteristic of a theory is that is has survived repeated attempts to falsify it.

The amount of sunlight available should depend on the size of the area they cover. What area of sea floor would they need to cover to produce an amount that could build the chalk cliffs or all the chalk formations on earth? Lots. Have a look at this map for starters.
The green bits are calcareous ooze. Let's call that about 10% of the sea floor. A quick look round the Internet shows that these deposits vary in thickness from tens to hundreds of meters. Let's call it an average of 25 meters, which is extremely conservative. If all that was spread out on the ocean floor, then, that would be a thickness of 2.5 meters. Now based on sediment traps, the rate of deposition is between 1 and 5 centimeters per thousand years. Call it 5 everywhere (again, favoring you rather than me). So being generous all round, that would be 50,000 year's worth of sediment if the whole of the ocean surface was dedicated to the production of coccolithophores and foraminiferans, which it isn't. That's before we get onto the actual rocks, and before we consider whether even a magic flood could sweep up the ooze into neat zones which just happen to correlate perfectly with the places that the calcareous-ooze-forming organisms happen to live in at present.

Good point, the effect of sunlight isn't an issue after they've died and fallen to the sea floor. The depth of that accumulation isn't a problem then, and the more the better.
\ So the question really is how much of the water where the sunlight penetrates would they need to occupy without putting each other in the shade, in order to produce enough to build the cliffs and other formations? And another question occurs whether they move around enough so that a great depth of them could receive sunlight in their turn. As for currents at the bottom of the ocean during the Flood, the event is described as beginning with the release of the "fountains of the deep," which is not exactly clearly understood but it suggests some activity deep in the ocean that could have created currents to bring deeply lying things to the surface.

A Floodist like me would hypothesize that the cliffs were like any of the thick strata anywhere on the earth, the result of the transportation by water of already-formed already-existent particles to their current location, and that before the Flood conditions were such that it didn't take so long for them to accumulate anyway. Any reason why this isn't possible? I'll add one that hasn't been mentioned yet: they are layered in their deposits in the Dover cliffs, they can be distinguished by their forms - as can diatoms and foraminifera - and the ones at the bottom are different from the ones in the middle and both are different from the ones at the top, and in between they go through many evolutionary processes that can be observed and documented. To have them dumped as you propose would not work because the layers would be jumbled not sorted, and would not show the pattern of development from bottom to top. This is no different from over 65,000,000 years of foraminifera deposits on the sea floor being layered in evolutionary strata that shows speciation and differentiation from bottom to top ... no different from the layers of marine deposits in mountains (like Mt Everest even) that show evolution from bottom to top instead of the jumbled mish-mash of creationist ignorance ... no different from the rest of the world ... So no, they can't be sucked up and piled from some world-wide distributions of dead deposits of purported pre-flood fantasy stockpiles. The world is OLD Faith, very OLD, get used to it.

Of course I do not accept that interpretation of the ordering of fossils as proving evolution up some fantasy time scale. There has to be a mechanical principle of sorting that explains it.
