This study investigates the impact of deep-sea shipwrecks on marine microbiomes. Researchers found that the richness and diversity of microbiomes increase closer to the *Anona* shipwreck in the Gulf of Mexico, demonstrating an 'island effect'. A halo of core taxa extended up to 200 m from the wreck, highlighting the shipwreck's significant influence on the surrounding seabed. This contrasts with smaller transition zones observed around natural habitats, suggesting shipwrecks exert a larger impact. The abundance of shipwrecks globally makes them valuable sites for understanding biogeography on the seafloor.
