Long Island Sound, semi-enclosed arm of the North Atlantic Ocean[1], lying between the New York[2]–Connecticut[3] (U.S.) shore to the north and Long Island[4] to the south.

Two glacial advances have deepened the sound’s water to more than 100 feet (30 meters); near its eastern limits it reaches a maximum depth of 330 feet (100 meters). The mean tidal range is from less than 3 feet (1 meter) in its eastern reaches to more than 6 feet (about 2 meters) in the west. The sound’s drainage basin[6] is nearly 13 times its area, and the annual volume of incoming fresh water is about 35 percent of the total. Most of the drainage of the Housatonic[7], Connecticut, and Thame...
