These reefs can take a huge range of forms, which is what makes them so cool. Sea life, like all life, really, is incredibly adaptable and resilient. Most artificial reefs take the form of sunken industrial remains or old ships, but there are also fascinating aberrations, like Florida's Neptune Reef—which is both a mausoleum for cremated remains and a thriving eco-habitat, as our sister site io9 reported last year—or the artificial reefs created by dumping decommissioned subway cars into the ocean.
And then there's this proposal, from a trio of French and Romanian architects named Quentin Perchet, Thomas Yvon and Zarko Uzlac, who won one of the Jacques Rougerie Foundation'sInternational Architecture Competition laureate awards this week. Ignore the name—BIODIVER[CITY]—and focus on the renderings, which show a huge floating platform that's accessed via boat on the surface. Below it, hundreds of tubular struts hand down into the ocean, serving as a place to cling for the coral and other microorganisms that thrive on reefs.
