Long Island Sound - West Chart

Long Island Sound - East Chart

Long Island Sound averages 60 ft in depth, with the greatest depth of over 300 ft at the eastern end. Tidal effects are strongest at the narrow western end, where all the inrushing water flow piles up and makes tidal variations of up to 7 ft. Strong tidal currents are also prevalent, and visibility tends to be poorer than the open ocean, especially at depth.

Yellow & Brown Algae

Pictured is a type commonly known as Rockweed ( Fucus vesiculosus, or Bladderwrack ) a tough northern type, adapted to the rocky shores of New England. However, it is more than happy to grow on jetties and pilings wherever it finds them and is quite common in the inlets around New Jersey. Like many other forms of algae, this one has gas bladders for flotation.
