Hudson Canyon

The Hudson Canyon is a submarine canyon that begins from the shallow outlet of the estuary at the mouth of the Hudson River, extending across the continental shelf beneath the Atlantic Ocean south and east of New York City, United States.

Description The Hudson Canyon extends out over seaward across the continental shelf, finally connecting to the deep ocean basin at a depth of below sea level. It begins as a natural channel several miles in width – starting as a depression at Hudson Channel southward from Ambrose Light, then carving through a deep notch of about depth in the shelf break, and running down the continental rise. Tidally associated flows of about up and down the deeper parts of the canyon have been recorded. As silt, sand and mud are carried down the Hudson River, they flow into the canyon and out into the deep sea.

The canyon is located near the isobath on the continental shelf and is deep at the base of the continental slope. Over a distance, the average slope of the canyon floor is 1.5°. At this point, the canyon is as much as wide (from east rim to west rim) and as much as deep from canyon rim to canyon floor across the continental slope. The floor of the Hudson Canyon is less than wide across the upper part of the slope and broadens to about at the base of the slope.

"Hudson Canyon" also designates a location marked by a navigational buoy indicating the seaward end of the vessel traffic separation scheme of the Hudson Canyon–Ambrose lanes which lead into and out of New York Harbor for Atlantic shipping.
