new comment[edit]

3/12/13: Page claims that northern-most dunes are in Canada, at 59deg north; but the Great Kobuk Sand Dune is ~ 67deg north? (http://en.wikipedia.org/wiki/Kobuk_Valley_National_Park). — Preceding unsigned comment added by 165.83.50.76 (talk) 23:06, 12 March 2013 (UTC)

old comments[edit]

Embryo dune is the phrase I was taught, and I seem to recall seeing in an OCR textbook. The term refers to the newest dune before it has been colonised and become the fore dune. --Steinsky 02:50, 16 Aug 2003 (UTC)

I think embryo dune could be a real word. The problem I am having is that it was described as being at the swash line (i.e., on the beach, not the dune). I suspect that the sequence you were taught seems to apply to dune systems that are behind a beach that is always advancing seaward. That is the only explain I can think of for the description of succession as if it were laid out on a sequence of dunes. That seems to me to be atypical. The youngest dunes are typically not the ones nearest the sea with the oldest ones furthest inland, except that the near ones might be disturbed by the sea more frequently and therefore less advanced in their succession. But I'm certainly not knowledgeable enough with all dune systems to say there are not systems in the world exactly as you describe them. At some point we will need to differentiate between the types. -- Marshman 16:59, 16 Aug 2003 (UTC)

Just thought I'd point out that dun is not a Germanic word. See Dun. 80.47.247.173 15:48, 7 October 2006 (UTC)

Dune by Frank Herbert[edit]

When I searched Dune I was looking for an article about the sci-fi work by Frank Herbert, not the geographical formations. Could there possibly be a disambiguation page for this? What the ----?


The page is getting crowded with pictures, would you like me to put some in a gallery?

Notes, please[edit]

Vernon, whenvbjvb hjhen.wikipedia.org/w/index.php?title=Dune&diff=169426247&oldid=169345107 this edit], which was actually mine? Working with that assumption, I did leave a note, specifically "dab header (the 'for other uses' bit at the top) covers one (your addition)". I apologize if that was unclear, but the attempt was made. -Bbik 22:39, 6 November 2007 (UTC)

dunes[edit]

wikipedia is basicly not telling me enough information about dunes. all the information that was givin to me was mixed up unorganized unimportant junk. come on i see why my teachers tell me that this website is fake with fake information and fake everything —Preceding unsigned comment added by 65.10.186.85 (talk) 18:44, 30 September 2008 (UTC)

Layout Cleanup Needed[edit]

Not sure how to do it (effectively), but could someone reflow the text and images for readability? It's tough with all the jumps in the text. — Preceding unsigned comment added by 152.130.11.197 (talk) 13:25, 2 September 2011 (UTC)

Stationary Dunes[edit]

In this (and other articles), the term 'Stationary Dune' is used but not defined. Could somebody with the appropriate background please provide a formal definition in the appropriate location. Whatthefat (talk) 19:00, 25 October 2011 (UTC)

Megaripples[edit]

While linking in from elsewhere, discovered this page gives a definition for megaripples which implies they are always submarine. This is clearly not true - there's famously megaripples on Mars, for instance - but I don't have the specific knowledge to replace it with anything else. See also Ripple_marks#Wave-formed_ripple_marks. IIRC is the process distinction between megaripples and dunes due to with the scaling of the feature to the particle step length and/or the flow boundary layer (ripples have boundary layer detachment at the crest and a vortex on the lee side; dunes don't)? DanHobley (talk) 14:22, 29 April 2012 (UTC)

Yes, New Scientist has confirmed my suspicions. It's all about the interaction with the boundary layer. Ripples only disturb the flow near to the bed; dunes perturb the flow much more deeply. http://www.newscientist.com/article/mg20227034.800-largest-megaripples-on-earth-discovered.html — Preceding unsigned comment added by DanHobley (talkcontribs) 14:32, 29 April 2012 (UTC)

Move discussion in progress[edit]

There is a move discussion in progress which affects this page. Please participate at Talk:Dune (disambiguation) - Requested move and not in this talk page section. Thank you. —RM bot 16:20, 16 May 2012 (UTC)

Planets around Arrakis[edit]

What are the other planets before and after Arrakis??? — Preceding unsigned comment added by 85.11.74.80 (talk) 15:41, 11 June 2012 (UTC)

Moved to Talk:List of Dune planets#Planets around Arrakis: Moved from real world geology/geography to an article more closely related to the astronomical aspects of the fictional Dune universe. See also the template.

Disambiguating "dune"?[edit]

Not a "requested move" yet. I don't know which is the suitable name for this topic, as others are probably looking for dune (novel) and dune (film). Should "dune" be:

  • dune (sand)
  • dune (geology)
  • sand dune

Any other suggestions before I move on to another "requested move"? --George Ho (talk) 18:32, 12 November 2013 (UTC)
