Underwater mystery revealed

Here's an interesting story from Florida concerning an innovative idea from the students of the Florida Keys Community College.
Ever wondered what the reef off the Florida Keys might look like on a map? Well, now you'll be able to see it.
Here's the story, from the Miami Herald. Read the full story here.

Equipped with floating GPS units, side scan sonar and waterproof paper, college students dove 25 feet down into an underwater classroom with a pioneering assignment: create a three-dimensional, interactive map of a reef.
When completed, the map will show both the contour and biological life on Looe Key reef, considered one of the most beautiful dive sites in the world.
"It's the first time this type of project has been done in the Keys," said Patrick Rice, director of marine sciences at the Florida Keys Community College.
Just as a tourist map of Key West marks Ernest Hemingway's House and the Southernmost Point, the portion of Looe Key mapped by Rice's class will highlight points of interest such as spectacular coral head formations and known hangouts for Goliath grouper and other territorial sea creatures.
"A lot of divers do underwater photography," said Lucja Jakuvowska, a student from Poland. "So if they come and can do only one dive on a certain dive site, they can just look at the map and go, 'Oh, I want to see this, this, this and this.' "
The 3-D underwater maps also will provide valuable baseline data for marine researchers, Rice said.
For years, federal agencies, including the National Oceanic and Atmospheric Administration and the U.S. Geological Survey, have mapped reefs in 3-D in the Keys.
"We are taking it to the next level by making it interactive and incorporating the biological data," Rice said.
The maps have the potential to work in conjunction with the new Google Ocean technology, in which a person can zoom into a specific location in a body of water and see what it looks like, Rice said.
Each of the 14 students in Rice's class had specific tasks to accomplish during their two approximate 45-minute dives at the east end of Looe Key reef known as the Towers. Some outlined the perimeter. Others took photographs or video of special features or creatures.
Student Nick Corby of Pennsylvania conducted a fish survey, coming up with 50 species that included stingrays. And one student operated the side scan sonar that produced high-resolution bathymetry.
The raw data was collected and combined using a quick grid program, which pumped out a topographical image. Video gaming software will be used to put in the color and points of special interest, and make it interactive with the photographs and video.
"You'll be able to take a simulated dive on Looe Key," Rice said.
