Wreck of the RMS Titanic intact and undamaged dresser behind it. Robert Ballard has suggested that areas within the ship or buried under debris, where scavengers may not have been able to reach, may still contain human remains. According to Charles Pellegrino, who dived on "Titanic" in 2001, a finger bone encircled by the partial remains of a wedding ring was found concreted to the bottom of a soup tureen that was retrieved from the debris field. It was returned to the sea bed on the next dive. The longest-lasting inhabitants of "Titanic" are likely to be bacteria and archaea which have colonized the metal
Opening of the North Atlantic Ocean The final major phase of breakup occurred in the early Cenozoic, as Laurentia separated from Eurasia. As the two plates broke free from each other, the Atlantic Ocean continued to expand. The Iceland plume is a mantle plume under Iceland that carries hot material from the deep within Earth's mantle upwards to the crust. The rising hot material weakens the lithosphere, making the separation of plates easier. The flow of hot plume material creates volcanism under the continental lithosphere. Iceland extends across the Mid-Atlantic Ridge. The Mid-Atlantic Ridge is a divergent plate boundary, and it separates the Eurasian and North
