'Euphotic' vs. 'Photic'

Regarding the page edit 23:03, 19 October 2006 71.67.104.37 (Error in wording of Photic should be "Euphotic"), can anyone verify this? If the correct word is Euphotic as suggested and not 'Photic', I suggest moving the article as well to reflect this. Rob.desbois 14:04, 21 November 2006 (UTC)[reply]

Both terms are used – there has also been some discussion of which should be the main title of the article.

Google is inconclusive, listing 60k~70k hits for both “photic zone” and “euphotic zone”, so the current title (Photic zone) seems fine, unless someone has a compelling reason otherwise.

Disphotic versus aphotic

Could someone define the 'disphotic zone' (undefined in the current article) and distinguish it from the aphotic zone. Briancady413 (talk) 10:29, 22 October 2011 (UTC)[reply]

'Photic' vs. 'Epipelagic'

To what extent is 'epipelagic' a synonym for 'photic' (along with 'euphotic')? It seems like they have heavily overlapping definitions. The fact that Epipelagic is shown under 'Aquatic Layers' as the one and only subdivision of Photic reinforces the impression that they are seemingly the same, but somehow confusingly not. The article should probably address this directly, eh? --Oolong (talk) 22:39, 12 March 2012 (UTC)[reply]

Ahem... changing my user name to Photic Zone won't do at all. There is some overlap in that both point to much the same zone, but the way the zones are viewed is quite different. The photic zone is the sunlit zone where enough sunlight penetrates for photosynthesis. Aquatic plant life, such as algae, thrive there. The depth of the photic zone varies over the course of a day, and depends on cloud cover and how turbid the water is. I suppose you could argue that at nighttime there is no photic zone. Epipelagic just means surface waters. There is no consideration of sunlight there. However the depth of epipelagic waters is usually defined as about 200 metres, which happens to coincides roughly with the typical depth of the continental shelf and the depth of the photic zone on a sunny day in clear waters. However, the terms are used quite differently. Thus you would talk about algae as needing to live in the photic zone, but fish which live in surface waters are called epipelagic fish, and not photic fish. If you want more complications, there is the neritic zone... --Epipelagic (talk) 00:32, 13 March 2012 (UTC)[reply]

Article’s talk page Sentence:

The article's talk page clears up any distinctions between terminology. ' Article Talk Page Paragraph

The author asks questions regarding the definition of disphotic zone vs aphotic zone, how much of a synonym is epipelagic to photic, and the difference between euphotic and photic. He/She believes that epipelagic and photic are quite different because the photic zone is the sunlit zone where enough sunlight penetrates for photosynthesis. He states aquatic plant life flourish there and the depth alters on the daily. According to the author, epipelagic just means waters not the surface and have no guarantee of having sunlight, therefor it cannot be regarded as the same as photic zone.
