Research Shows that Shipwrecks are Valuable Ecological Resources

A new study published in the journal Bioscience highlights the ecological value of shipwrecks, which are estimated to number three million on the seabed. The study argues that wrecked vessels create rich underwater habitats for a variety of organisms, serving as artificial structures that support a thriving ecosystem. Microorganisms, algae, invertebrates, and fish all benefit from the presence of shipwrecks, while larger fish and predators use them as feeding grounds and rest stops.

While shipwrecks act as biodiversity hotspots, they can also harbor invasive species that negatively impact the surrounding ecosystem. The study also raises the possibility of better understanding the ecology of other submerged manmade structures, such as artificial reefs, and suggests creating a global “biocultural heritage” monitoring network for shipwrecks. The research sheds light on connectivity, succession, disturbance, and degradation processes in the marine ecosystem, offering valuable insights for conservation efforts.

The team of scientists behind the study includes researchers from various institutions, and their findings emphasize the need to protect wreck sites for both their ecological and cultural significance. The study calls for a greater understanding of the ecological value of shipwrecks and suggests the establishment of a monitoring network to aid in their conservation.
