All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.
This site on the Shark River Artificial Reef consists of two long ridges of seven huge rock piles each, with one long valley east-west between them. Between piles, there are smaller valleys. Each ridge contains approximately two million tons ( or one million cubic yards ) of granite, blasted and dredged from the bottom of New York harbor between September 2002 and September 2003. Peak depths range from 85 to 105 ft, bottom depth is 130 ft. In addition, 15 Redbird subway cars were deposited on or near one of the piles. A similar rockpile is located in shallower water on the Axel Carlson Reef.
Rare mauve stinger jellyfish found at the Jersey Shore. Its sting is 'intense,' scientists warn.

Maggie McGuire was at Sea Watch Beach in Manasquan with her family Monday when they spotted something unusual in the water - a small, umbrella-shaped, purplish-pink jellyfish speckled with dots. They scooped one up with their bucket and let it swim around in the water before eventually releasing it on the other side of the beach, away from swimmers.
"The water was literally filled with them," McGuire recalled. Her kids caught and released probably a dozen, she estimated, and other kids were doing the same. She did a quick search online, found a Facebook group - New Jersey Jellyspotters - and posted photos of the jellyfish. Two marine biologists reached out and informed her they were mauve stingers, a species rarely found on New Jersey beaches.
