Gigantic New SuperOrganism with 'Social Intelligence' is Devouring the Titanic
In 2000, Roy Cullimore, a microbial ecologist and Charles Pellegrino, scientist and author of Ghosts of the Titanic discovered that the Titanic --which sank in the Atlantic Ocean 97 years ago -- was being devoured by a monster microbial industrial complex of extremophiles as alien we might expect to find on Jupiter's ocean-bound Europa. What they discovered is the largest, strangest cooperative microorganism on Earth.
Scientists believe that this strange super-organism is using a common microbial language that could be either chemical or electrical -a phenomenon called "quorum sensing" by which whole communities "sense" each other's presence and activities aiding and abetting the organization, cooperation, and growth.
The microbes are consuming the wreck's metal, creating mats of rust bigger than a dozen four-story brownstones that are creeping slowly along the hull harvesting iron from the rivets and burrowing into layers of steel plating. The creatures also leave behind "rusticles," 30-foot icicle-like deposits of rust dangling from the sides of the ship's bow. Structurally, rusticles contain channels to allow water to flow through, and they seem to be built up in a ring structure similar to the growth rings of a tree. They are very delicate and can easily disintegrate into fine powder on even the slightest touch.
These live mats and rusticles form a communicating super-organism funneling iron-rich fluids, sulfur, and electrical charges through the collective of archea, fungi, and bacteria that thrives in the icy dark, low oxygen waters. Using DNA technology, researchers discovered that the rusticles were formed by a combination of 27 different strains of bacteria. Among the bacteria feasting on the Titanic, there was a brand new member of the salt-loving Halomonas genus.
In June 2003, NOAA’s Office of Ocean Exploration sponsored an 11-day research cruise to the wreck site aboard the Russian Research Vessel Akademik Mstislav Keldysh. The vessel is equipped with two three-person submersibles (Mir I and Mir II) capable of diving to depths of 6,000 meters; the depth of the Titanic is 3,800 meters (12,467 feet).
OE planned four Mir dives to the Titanic to assess the wreck site in its current condition, and provide an opportunity to conduct scientific observations for ongoing research. Scientists from the United States and Canada were invited to participate in the expedition.
Larry Murphy, chief of the Submerged Resources Center, National Park Service, was on hand to provide archaeology assistance and advice. His expertise on metallic shipwrecks and site formation processes from the USS Arizona Memorial directly complements NOAA’s guidelines on Titanic. Dr. George Bass, known as the “father of maritime archaeology” from the Institute of Nautical Archaeology (INA), also joined the trip to offer archaeological expertise.
More than 24 hrs of annotated, on-site video data were acquired and catalogued, used to construct a photo mosaic of the wreck site, provide a context for site characteristics, and form a better understanding of site formation processes. The stern section of Titanic, which has largely been ignored in the past because it is in a jumbled state, was specifically analyzed.
The second objective of the expedition addressed microbial communities, the rusticles, that consume Titanic’s iron and cling to the wreck like rusty icicles. These features have been observed throughout the years. Ongoing qualitative analyses contribute to the scientific research regarding the ship’s degradation. Roy Cullimore and Lori Johnston from Droycon Bioconcepts, Inc. (DBI) of Canada organized the microbiological and rusticle observations.
