The 3. 000 oil/gas structures currently deployed in the northern Gulf of Mexico (GOM) provide hard substratum for marine organisms in a region where such has been rare since the Holocene.

Corals are known to have colonized oil/gas platforms around the FGB. https://www.chiggate.com/igora-vibrance-4-99-medium-brown-violet-extra-sale/
