Coming to the res- cue was the Seabotix model 150 ROV, which confirmed that the Ghost had been found. July 2006 will see a full recovery effort using work ROVs brought in by float plane, the only means of moving man and machinery into this remarkably pristine and uninhabited site. In July, the mission will be carried out and communicated via web cast, as the Fokker is prepared for extraction by ROVs and divers, finally breaching the surface after 73 years and is airlifted off to its new home in Winnipeg.

Imaging

To help locate and resolve post-Katrina hazards lurking beneath the murky waters of the Port of New Orleans'

Inner Harbor Navigation Canal, Boh Bros.Construction

Co., L.L.C. of New Orleans tapped into some innovative underwater imaging technology via C.H. Fenstermaker &

Associates Inc. "High-definition underwater acoustic visualization is changing the way we see the world," said Ken LaBry, manager of the firm's Acoustic Imaging Group. "We have assembled a team of qualified personnel and given them the best tools possible for performing this work. The imaging services we currently use provide our clients with unparalleled precision in underwater applications."

Using specially configured scanning sonar and software,

Fenstermaker's Acoustic Imaging Group is gathering visu- als of the underwater portions of support structures for vehicular and railway bridges that cross the canal at

Almonaster Ave., Florida Ave. and Seabrook and analyz- ing them for damage.

The group is also scanning the canal for sunken barges, ships, boats and other debris that could impede harbor traffic. The results are then shared with Boh Bros.,

Modjeski and Masters Consulting Engineers and the U.S.

Army Corps of Engineers.
