Talk:Marine transgression

Mergeto Sea level rise
This article says that transgression is the opposite of regression, yet there is no article on that. Sumbuddy should write a stub on regression (geology) and link it at regression (which is where I found this article).  Randall Bart    Talk   18:28, 24 December 2007 (UTC)

Wow. I thought I was creating a redlink, but regression (geology) is a redirect here. Still, a separate article, even if just a stub, is warranted.  Randall Bart    Talk   18:30, 24 December 2007 (UTC)

Well I found the article at Marine regression, and I'm redirecting regression (geology) there. From there I found an article called Sea level rise. That's a meaty article, so I'm adding a mergeto to this article.  Randall Bart    Talk   18:39, 24 December 2007 (UTC)


 * Disagree with merge. A marine transgression is caused by sea level rise (generally isostatic) but it is not the same thing as sea level rise. It implies an advancing coastline, and an advancing series of depositional environments, which is not the same as the water just getting deeper, though obviously it is a consequence of this. The sea level rise article is and should be about causes and short-run effects of sea level rise, global warming, human impact etc. This article should be about the geological record left by marine transgressions. Ditto the matching article about regression. If you want to cut down the number of articles, merge the two geology ones, not the general one on sea level.Pterre (talk) 23:50, 31 January 2008 (UTC)
 * Oops - of course I mean a retreating coastline - coastal erosion etc. Pterre (talk) 12:34, 2 February 2008 (UTC)
 * Diasgree. Transgressions often occur in the geological record due to local tectonic effects, e.g. as areas subside during rifting, and these have nothing to do necessarily with global sea level changes. Mikenorton (talk) 16:36, 17 April 2008 (UTC)


 * Oppose merge: for practical reasons: the sea level change article about current phenomenon and is prone to controversy; this one is old solid science.--Qyd (talk) 17:01, 9 February 2009 (UTC)
