DP2 DSV Pertinacia to conduct the initial salvage survey, recover remaining fuel, lube oil and dirty oil as well as place the salvage bundle rigging. Once on location the sal- vage team rigged the D/B Lili Bisso to the pre-placed salvage bundles. The vessel was lifted upside down, rather than first being uprighted, to mitigate the risk of pipeline damage during a righting attempt. Monitoring Survey of Deepwater Reefs Several deepwater reefs have been discov- ered off Florida in recent years, and very lit- tle is known about these reefs because exploration has been limited. Harbor Branch Oceanographic Institution scien- tists are hoping to change that. A Harbor Branch team used the Johnson-Sea-Link II submersible, sub-deployed time-lapse video and listening devices, and towed nets to perform the first comprehensive survey. The survey focused on the Miami Terrace, a 65-km long platform that runs from South Miami to Boca Raton about 15 miles offshore in depths from 650 to 2,000 ft. (200 to 600 m). In addition to using the submersible to collect information about the reefs, the team also placed video and acoustic moni- toring equipment at study sites for longer- term monitoring. Time-lapse video record- ings will allow them to assess differences in the abundance and behavior of animals during the day and at night. news Visit www.maritimeequipment.com/mt & Click No. 205 MTR#6 (1-16).qxd 7/11/2006 12:03 PM Page 17
