Excerpt: A colorized depiction of the Hudson Canyon on the continental margin off New York and New Jersey at the outlet of the Hudson River.The Hudson Canyon is a submarine canyon that begins from the shallow outlet of the estuary of the Port of New York and New Jersey at the mouth of the Hudson River. It extends out over 400 nautical miles ( 450 miles or 750 km) seaward across the continental shelf finally connecting to the deep ocean basin at a depth of 3 to 4 km below sea level. It begins as a natural channel of several kilometers width, starting as a 20-40 m depression at Hudson Channel southward from Ambrose Light, then carving through a deep notch of about 1 km depth in the shelf break, and running down the continental rise. Tidally associated flows of about 30 cm/s (1 km/h) 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 Hudson Canyon proper is located about 100 miles (160 km) east of the mouth of the Hudson River off the New Jersey coast. Its walls rise three-quarters of a mile from the canyon floor making it comparable to the Grand Canyon, whose cliffs are over a mile deep and 270 miles (430 km) long. It is the largest known ocean canyon off the East Coast of the United States, and one of the largest submarine canyons in the world. The canyon is located near the 100 meter isobath on the continental shelf and is 2,200 m (7,217 ft) deep at the base of the continental slope. Over an 80 km (50 mile) distance, the average ...More: http: //booksllc.net/?id=3663219
