New Jersey sank 397 obsolete army tanks and armored vehicles from 1994 to 1997 in 40 to 140 feet of water; a five-year study found 432,000 animals of 145 species per square metre of reef habitat

In a remarkable initiative, obsolete US Army tanks were intentionally submerged off the New Jersey coast, creating vibrant artificial reefs that now host an impressive 432,000 marine creatures. This innovative project not only repurposes military surplus but also highlights the potential for such efforts to enhance aquatic ecosystems, emphasizing the importance of thorough preparation and monitoring for environmental success.
