candidate: Several hiccups happened during this expedition , as several hurricanes were passing over the wreck site , and the team got the " Remora " ROV caught in a piece of wreckage in the " Titanic " s expansion joint , and carefully had to get the robot out of the expansion joint to avoid damaging the " Titanic " , as the " Titanic " , having been underwater for 98 years , was in very fragile condition , and one of the AUVs , Ginger , was weighed down by a piece of the lead anchor discovered in 2005 .
