The rewrites to date look good. Unfortunately the bathymetry plot stops at 110m; is there something better for the 1 km deep region? I can only find the NOAA continental slope plot.rmo13 18:19, 5 September 2006 (UTC)[reply]

Copyright problems?

There seems to be a fair amount of text in common between this article and Scientists Map 'New Frontier' Deep Within Ocean, by the AP. For example, sentences and phrases like Landslides in the Hudson Canyon could cleave undersea phone cables that handle much of the nation's overseas communications, and although no technology yet exists to extract the .... Do we have a copyright problem here? -- RoySmith (talk) 14:50, 30 September 2006 (UTC)[reply]

Besides most of that text is generic to submarine canyons and more broadly to shelf breaks. It's also unsourced.rmo13 21:10, 1 October 2006 (UTC)[reply]

Creation

Can someone explain how the discharging of sediment would create the canyon? I would have thought that the discharging of sediment would be more likely to create a delta or fan. Jason A. Recliner (talk) 15:26, 27 August 2008 (UTC)[reply]

Or, to add to that, the glacial dam outburst event that separated Staten Island from Brooklyn and help create the Long Island Sound? Surely that much water would have had an effect carving this out.Frunobulax (talk) 19:28, 16 February 2019 (UTC)[reply]

No Merge?

It is a different landform from the New York Bight so why merge? Hugo999 (talk) 05:49, 16 August 2010 (UTC)[reply]

Bioresources

I had heard that the terminal zone of the Hudson Canyon was rich in fish and other bioresources. If so, this should be mentioned. — Preceding unsigned comment added by 72.70.206.131 (talk) 18:13, 23 March 2012 (UTC)[reply]

It is mentioned on the Hudson River page. Perhaps that text could be brought over here? (29 May 2014)

Comparison to Grand Canyon and rate of erosion

Various estimates say that it took 5 - 17 million years of erosion to carve the Grand Canyon to its present depth. But the Hudson Canyon article says the canyon formed during the most recent ice age, which implies a rate of erosion several orders of magnitude faster. Naturally, we should be skeptical of this.

Could an actual geologist please add a correction or explanation to the article? 174.24.25.153 (talk) 18:47, 27 December 2014 (UTC)[reply]

Methane clathrate unsourced weaseling

I've removed the following paragraph from the article:

Submarine canyons are believed to contain vast reserves of methane hydrates, believed to reside in near freezing temperatures under high pressures within sea floor sediments, although no technology yet exists to extract the methane. These methane deposits are dispersed under the ocean floor over millions of square miles in this and other areas of the world. Some scientists speculate that the methane gas pockets in the underwater shelves could cause undersea landslides that might produce tsunamis. Landslides in the Hudson Canyon could also slice through undersea telecommunications cables that handle much of the nation's overseas communications.

Seems the first two sentences are general comments about methane clathrates with no mention of evidence for their abundance (or even presence) within the canyon. Then follows the weasel: "Some scientists speculate ..." about possible "landslides". Citations needed for the presence/abundance of clathrates here and to de-weasel. Feel free to rewrite and return the basic info based on solid references and w/out the weasels. Vsmith (talk) 00:34, 28 March 2015 (UTC)[reply]
