Proper Name[edit]

While I understand there are subtle differences between abyss, trench, fan and valley, considering that its official name is the "Laurentain Abyss" shouldn't that be the name this page is under? 173.209.103.10 (talk) 20:16, 16 May 2019 (UTC)[reply]

Info[edit]

Im looking for some location and charting information for the Laurentian Abyss. I know that it exists on Oceanography maps but do not have any to get significant information from. Anyone who comes across this page and doese plese post it on the main definition page. -Thanks, LeibstandarteAdH

Excerpt[edit]

Here is an excerpt from another site:

The deep ocean floor is mostly flat but there are quite a few seamounts, guyots and deeps or trenches. The deepest trench in the North Atlantic is the Puerto Rico Trench at 8,605 meters, in the South Atlantic it is the South Sandwich Trench at 8,428 meters and near the equator is the Romanche Trench at 7,454 meters. The deepest point in the Atlantic is at 8,605 meters and is called the Milwaukee Deep, an area located in the Puerto Rico Trench. Off the eastern coast of Canada is the Laurentian Abyss. The shelves that run along the edges of the continents make up approximately 11% of the bottom topography in addition to several deep channels that cut across the continental rise. —Preceding unsigned comment added by 165.166.156.10 (talk • contribs)

What's the other site? If it's a reliable source we can cite it here.--Tbeatty 18:30, 7 April 2007 (UTC)[reply]

The above information was cited from: http://marinebio.org/Oceans/Geography.asp –LeibstandarteAdH 15:12, 8 April 2007 (UTC)[reply]

This info can add to the Laurentian Abyss main page but still leaves much to be desired such as coordnates and depth/depths. As i said which i believe can be gained from simple oceanographic charts if anyone has acess. That does not make the above information any less relevent, and should still be added. --165.166.156.10 18:32, 8 April 2007 (UTC)[reply]

Confused[edit]

- - - - I am confused about something noted in the Laurentian Abyss article. At the end, it states that "the actual deepest point is the Challenger Deep in the Pacific Ocean." Yet when I went to the Wikipedia article about the Challenger Deep, Wikipedia states that it is the "third deepest point." Ok, one article is in need of correction.************

This whole article is a joke. The "sources" are erroneous, less than credible, and contain little to no actual information about this supposed trench which only ever seems to appear in sci-fi. —Preceding unsigned comment added by SnOrfys (talk • contribs) 13:57, 12 August 2008 (UTC)[reply]

Ok. I have spoken to a professor of Geography at Memorial University in Newfoundland, and have gathered that the Laurentian Abyss is more of an underwater valley off the eastern coast that is at most 200m below the continental shelf and at most is ~600m deep. It is a product of glaciation and the currents from the St. Lawrence Seaway. Once I get ahold of some GIS maps, I'll update. —Preceding unsigned comment added by 198.96.76.109 (talk) 17:59, 15 August 2008 (UTC)[reply]

Marking this as needs references[edit]

This needs better depth sources. I'm marking it as citations needed. cOrneLlrOckEy (talk) 18:49, 3 September 2008 (UTC)[reply]

Does this exist? Can't find any valid references to it, although there is a nearby Sohm Abyssal Plain that contains an area called the Laurentian Fan. There are several references to this online (including a bouy monitoring station from NOAA), here's one from several university authors in 1983: http://www.springerlink.com/content/x3w6p49u01374pnh/

Atlas of Canada lists Sohm Abyssal and Laurentian Fan, no Laurentian Abyss. http://atlas.nrcan.gc.ca/site/english/index.html (seach for Abyss, the direct link to it is too long to post here). There is a Laurentian Gulch but it appears to be a cove area of the Newfoundland/Labrador coast. Halfdragon (talk) 22:07, 7 January 2009 (UTC)[reply]

Inconsistency in the intro[edit]

First it says "Not a trench", but then it later goes on to say "The trench is the site of hydrothermal vents"; is it a trench, or isn't it?--PrintedScholar (talk) 23:05, 21 November 2011 (UTC)[reply]

Coordinate error[edit]

{{geodata-check}}

The following coordinate fixes are needed for The Laurentian abyss is located in the Atlantic Ocean. The coordinates shown (42° 4′ 56.93″ N, 52° 4′ 21.26″ E) are located in the Caspian Sea.

Done. The problem seems to have simply been a mistaken use of east longitude when it should have been west longitude. I've also tweaked the coordinates, making them less precise for such a large feature. Deor (talk) 13:48, 10 June 2016 (UTC)[reply]
