Deep sonar and more high-tech ships were involved in the search to find a missing submersible which disappeared June 18 on the way to the ruins and wreckage of the Titanic with five people aboard. The search area grew exponentially to twice the size of Connecticut. Susan Lozier, Dean and Betsy Middleton and John Clark Sutherland Chair of the College of Sciences, and a professor in the School of Earth and Atmospheric Sciences, said the spot where the RMS Titanic wrecked in 1912 is home to treacherous conditions both above and below the water. “The thing to keep in mind, just the surface conditions, boats and everything involved in this rescue operation, this part of the ocean is where the Gulf Stream continues up northward very energetically, and interacts with the atmosphere, a stormy area,” said Lozier, a physical oceanographer who has researched ocean currents in the North Atlantic. (Lozier was also interviewed by Atlanta News First.)
