Talk:Atoll

message: Don't know about plagiarism but it lacks a real description of a typical atoll itself, such as the presence of a fresh water lens floating in the permeable coral material above sea level. Significant to human habitation. Lukunor 00:27, 11 December 2013 (UTC)
replies: text: Are you talking about pictorial plagiarism? This article is one of the one(s) that should not be confused with the OT story of Noah and his Ark, nor any of the historically accurate points along the evolutionary time line of today's human beings AND it is one of the one(s) not to be confused with this article NOT because it requires your interpretation of biblical stories such as Adam and Eve to be read as the appearance of an organism that reproduces sexually (ie the appearance of a species divided into genders as opposed to the first appearance of gendered Human) but rather the not to be confused warning is due to the visual semblance of atoll forming to the evolutionary event of eukaroytic cells begatting it's organelles (such as the currently recognized  mitochrondria.) I am not sure there is a fix for your problems, other than a yet-to-live red-lettered link to a specific interpretation of a synopsis to the Noah's Ark story with which this article is not to be, confused with. -Dirtclustit (talk) 18:48, 5 October 2015 (UTC)

----
This page has a great deal of text that appears to be extensively (if not entirely) plagerized from some old textbook (the style is very olde English).  Beyond the section describing (in some places incorrectly) the relationship between volcanoes and atolls, the next two sections on volcanoes and diatoms bear NO relationship to the subject of atolls. I suggest complete removal of the page (owing to lack of attribution), returning to the earliest, single line definition to refleshed from there. Marshman 02:25 26 Jul 2003 (UTC)
I've since replaced the old plagerized stuff with new content to cover the subject Marshman 17:41 28 Jul 2003 (UTC)
Marshman, you have done good job on the article, it is certainly an improvement over what was orginally here.  I just have a query about the statement that atolls are limited to the oceanic basins of the Pacific and Indian oceans.  I thought they could also be found in the Atlantic ocean such as Rocas Atoll of the coast of Brazil. -- Popsracer 00:08 29 Jul 2003 (UTC)
I am starting a new paragraph on atoll distribution and admit to being a bit out on a limb there. I woulld want to know more about Rocas Atoll and perhaps a few others associated with the Great Barrier Reef before proceeding down the interesting road of the relationship between atolls and oceanic hot-spots.  Any help appreciated.  Your catches on my contribution have been right on. Marshman 00:49, 29 Jul 2003 (UTC)

Also, do prehistoric meteor strikes ever qualify as atolls, or is an atoll strictly a volcanic/erosion formation? —The preceding unsigned comment was added by 65.216.235.42 (talk) 17:18, 5 April 2007 (UTC)
thread_title:  Northernmost atoll & strict definitions 

message: I tried to list the largest atolls by total area, including the submerged ones (their inclusion may be a matter of dispute, though). Most of the size information is from , and I tried to complete the list of the largest atolls from other sources. From , I did not use the Amirantes Bank (3951 km²), which is obviously not an atoll, but has atolls on it. I am not certain about the atoll status of all entries in the list. If you are certain that one or another is not an atoll in the geomorphological sense at any stage of development, please explain (if possible with sources) and delete the entry.--Ratzer 09:02, 18 May 2007 (UTC)
thread_title: Largest Atolls by total size

message: Are the Caicos Island an atoll by any chance? The spatial arrangement of the islands would suggest it (large islands along the northern rim, and smaller islets and reefs in the south). It would be the largest atoll of the world, measured by land size, and among the 10 largest by total size.--Ratzer 13:34, 18 May 2007 (UTC)
replies: text: What do you mean by "measured by land size, and among the 10 largest by total size"? I just checked and Kiritimati is bigger than these islands. -Indolences 13:56, 18 May 2007 (UTC)
replies: text: I also checked. About Kiritimati, widely differing land area figures are in circulation, one of about 388 km², and another of 642 km², as I found out just now. Judging from satellite images, the lower figure seems more plausible. For the Caicos Islands, I put a well researched land area figure of 589.5 km² in the article.--Ratzer 19:54, 18 May 2007 (UTC)

thread_title: Caicos Islands?

message: This article describes how a volcanic island subsides and coral reefs form to just under the water surface (barrier reef stage) but it doesn't really describe how the islands form. What is the incentive for the coral to grow above the water? Does there have to be a sea-level change large enough that the exposed coral can accumulate wind-borne sediment and bird detritus? Would that change have to be large enough that the nascent island wouldn't be swept clean by storm surges? Some details on this would be very useful! Franamax (talk) 18:46, 12 October 2008 (UTC)
thread_title:  Atoll island formation 

message: I find the explanation of atoll formation wanting. The graphic shows the centre of a volcanic island "subsiding", while the outside remains virtually unaffacted. What geological process could cause that to happen? That part seems not to be explained. 86.152.243.81 (talk) 13:56, 10 April 2010 (UTC)
replies: text: In the text, it is explained that atolls form when the rate that the island is sinking is less than the rate of growth in the coral ring around the island. Is the text unclear? --Danger (talk) 15:45, 10 April 2010 (UTC)
replies: text: My point is that the graphic does not show the island sinking uniformly. It shows the centre collapsing but the sides, to which the ring of coral is anchored, remaining roughly at the same level. I can't see it explained anywhere how or why that should happen, and I'm afraid I don't understand how your reply addresses this question. 86.165.23.205 (talk) 02:14, 11 April 2010 (UTC)
thread_title:  Formation 

message: This last section of the article mentions absolutely nothing about atolls and I deem it unnecessary. However when I tried to delete this irrelevant section, it was reverted back to the previous edit and I was given a message about vandalizing the article. So, can someone please impart on me the relevance of the last section(Nation Monuments), rewrite it to make sense, or delete it for me.
Thanks

message: I ask the same question asked by Franamax in Oct 2008 without getting an answer: how can coral end up above sea water?  — Preceding unsigned comment added by 173.33.80.7 (talk) 01:42, 19 March 2012 (UTC)
replies: text: The live corals themselves can't grow above sea level, but wind and waves throw up debris (dead coral, shells, etc) over the reef.  Eventually there is enough debris above sea level for vegetation to grow in it. Sea birds also bring in nutrients in the form of guano. The vegetation helps bind the land together. The island is never more than a few meters above sea level (unless sea level falls).86.144.114.34 (talk) 21:50, 8 July 2015 (UTC)
thread_title:  Formation: how can coral end up above sea level?

message: This definition is fundamentally wrong and completely contrast to modern definitions in Usage section. Basically, an atoll is no way a coral island but a kind of coral reef. The definition should be "Atoll is a kind of coral reef including a coral rim enclosing a lagoon.", not "an atoll is a coral island". Coral island(s) lies on the coral rim, hence it's a part of the whole atoll, not the atoll itself. Please review this. Autumnyear (talk) 03:35, 30 January 2013 (UTC)
replies: text: So I have to correct this by myself. I have added two good sources to the all important first sentence since the old definition is fundamentally wrong when mixing the coral reef with islands built on it. Atoll is a kind of coral reef (the others are mainly barrier reef, fringing reef and table reef or patch reef). There may be coral islands (low and flat, in many case are cays) built on the coral reef, so islands are parts of the whole atoll, not the atoll itself. Autumnyear (talk) 14:26, 12 February 2013 (UTC)
thread_title:  About the first sentence 

message: In this subsection one finds this verbiage stream:
Atoll islands are low lying, with their elevations less than 5 meters (9).
What might be the meaning or purpose of the characters " (9)" ?
It cannot be 5-meters converted to feet, because that would be 16-feet.
The "9" cannot be reference #9, because that spreadsheet from The Geological Society of America does not provide any data on the "elevations" of atolls.
If someone can provide a "units" for the "9", or a purpose, then I won't suggest we delete it.
P.S.: I do not know how to determine quickly which user inserted the "(9)" in order to ask them 'why'.
