The Coast Guard also confirmed to USA TODAY Thursday that a Navy analysis of acoustic data detected "an anomaly consistent with implosion or explosion" in the vicinity around the time the Titan lost contact. That likely explains what appears to have been the implosion of the vessel, said Wille and others. ![]() "The pressure inward on the sub would have been enormous," said Luc Wille, a professor and chair of physics at Florida Atlantic University. Stockton Rush, owner and founder of OceanGate Expeditions, was piloting the Titan with a group of four passengers when the submersible lost contact Sunday with its support ship about an hour and forty-five minutes after starting its dive. But even at higher depths than where it was found, any defect in the hull would have allowed the Titan to be crushed in milliseconds, experts in physics and submarines told USA TODAY Thursday. It will be difficult to know at what depth the Titan sub became overwhelmed. Parts of the sub were found about 1,600 feet from the Titanic, nearly 12,500 feet below the surface in icy, dark waters. The final moments of the Titan would have been swift – and unleashed amid a force difficult to comprehend.Ī North Atlantic rescue mission undertaken by at least four countries found that the submersible was destroyed by a likely implosion, scattering its debris on the ocean floor near the doomed luxury liner Titanic. In addition, the potential for build-up of excess pore pressure due to rapid loading from subsequent glacial depositions, their seabed smoothing effect, and great lateral extent, make the contourite drift deposits particularly important for slope instability in this region.Watch Video: What is a catastrophic implosion? What we know about Titan submersible The main influence of contourite drifts on slope stability relates to their physical properties forming a more sensitive and brittle deposit than the glacial deposits and their exposure to downslope sedimentation. The infill drifts consist mainly of clays with silty and sandy lamina and represents marine and glaciomarine conditions. This is equivalent to the estimated rates for the older infill drifts. Detailed chronostratigraphy of the post-slide sediments show relatively constant high sedimentation rates in the order of 1–2 m/ky during the last 8000 years. Holocene post-slide deposits in the scar of the Storegga Slide (8.2 ka) have the typical morphological features and distribution of contourite drifts with the upslope limit at the lower base of the warm northward flowing North Atlantic Current at 500–700 m depth and the downslope limit at depths of approximately 1200 m. ![]() During the last 0.5 My contouritic deposits occurred also in the Storegga area as 100–150 m thick infill drifts inside the scars of two palaeo-slides (R and S). Only on the Vøring Plateau was contourite sedimentation little affected by this change in sedimentary style. An increase in sediment supply from about 4 to 3 Ma, due to onshore uplift and glaciation, resulted in a massive influx of downslope-derived material onto the continental margin. ![]() These bedforms are morphologically classified as sheeted and elongated mounded contourite drifts. Between about 12 and 4–3 Ma, slope-parallel bottom currents dominated the Neogene sedimentation on the slope of the Mid-Norwegian margin, and large-scale sediment bodies accumulated to thicknesses up to 1000 m. ![]()
