How do you go about searching a capsized, 951-foot-long cruise ship?
In the footage below, you can watch the eerie scene that recovery divers have encountered during their rescue efforts on the Costa Concordia.
The recovery search was suspended temporarily on Wednesday, according to Reuters, when the cruise ship shifted slightly, which presented a danger to diving teams inside. The Guardian reports that rescue efforts have since resumed, with Navy divers given the clear to reboard the ship at 5 a.m.
The renewal of search efforts coincided with the pleas of Susy Albertini to find her missing 5-year-old daughter, Dayana Arlotti, The Guardian reports.
"Please continue to search for my child. Don't stop. Bring her home as soon as possible," Albertini told an Italian television station.
In addition to searching for the 20 people still listed as missing, special teams will now begin to pump the more than 2,300 tons of fuel from the ship to prevent an environmental disaster, the BBC reports.
"They'll be drilling into each tank, and pumping the oil out and putting it into a barge or a coastal tanker or even a tug," Mike Lacey, of the International Salvage Union, told the BBC. "If the weather turns against them, then they won't be able to work. So I understand they expect to take a week to two weeks to get all the fuel off."
The videos below from Reuters and The Telegraph illustrate the difficult conditions divers face during their search of the Costa Concordia. In addition to the entire ship being tipped on its side, divers must work in near darkness and deal with furniture and abandoned personal belongings floating in the water.
