Underwater robot competition offers impressive display of technical and design skills

Sixteen student teams from middle, junior and high schools competed in the 2016 Gray’s Reef Southeast Regional MATE ROV Competition at the Chatham County Aquatic Center on April 30. After a full day of competition, seven-time regional champion Carrollton High School won the right to advance to the international round, held in June at the NASA Johnson Space Center Neutral Buoyancy Lab in Houston.

Carrollton High School, located west of Atlanta, has fielded strong teams that have placed as high as ninth in the global competition. Its team InnovOcean holds high hopes of taking home the top prize this year and will compete against students from various locations including Canada, Russia, Hong Kong and Scotland.

Beginning in 2004, Gray’s Reef National Marine Sanctuary partnered with the Marine Advanced Technology Education, or MATE, Center to offer underwater robotics as a vehicle to teach science, technology, engineering and math.

The ROV competition requires students to build tethered underwater robots — called remotely operated vehicles, or ROVs — from scratch, and then challenges them to perform tasks simulating real-world operations conducted by exploration organizations like NOAA’s National Marine Sanctuaries, NASA and other marine agencies worldwide. Teams are able to choose from four different classes of competition defined by skill level, instead of age, which further illustrates real-world circumstances. Only two classes — the Explorer and Ranger levels — are eligible to compete at the international competition.

In order to win, teams must not only build and successfully pilot an underwater robot, they have to create a company to market and sell their ROV. Students prepare posters, product spec sheets, safety procedures, design abstracts, business cards and presentations to working professionals who serve as contest judges.

Led by Jody Patterson, events coordinator at Gray’s Reef National Marine Sanctuary, staff and sanctuary volunteers organize the regional competition and create simulated workplace scenarios for the ROV pilots. This year’s regionals focused on “innerspace” ROV tasks, including recovering equipment, conducting forensic fingerprinting of oil spills, analyzing deep water studies of corals and capping wellheads of oil rigs.

The sanctuary’s Team Ocean volunteer divers worked all day with NOAA divers to continually set up the underwater task components. Other volunteers served as judges and safety inspectors.

“It is a privilege to host the Southeast Regional ROV competition each year,” said Gray’s Reef National Marine Sanctuary Superintendent Sarah Fangman. “To properly protect marine life and special areas like Gray’s Reef, we need tools to help us explore and understand the mysteries of the ocean. These students — future engineers and scientists — will create the next generation of instruments used at NOAA, NASA and the maritime industries.”

Gray’s Reef conducts drifter and dye studies

 

In September, Gray’s Reef and its partner, Georgia Southern University, completed the last in a series of dye and drifter releases to track the outflow of the Altamaha River. The Altamaha is the third largest river basin on the Atlantic seaboard, and its watershed drains almost 25 percent of Georgia’s land mass.  It is also the closest freshwater source to Gray’s Reef, found 16 miles offshore.

By tracking the path of the dye and drifters, researchers can provide estimates of the extent to which the Altamaha River outflow delivers various contaminants, nutrients, freshwater and solid material to hard-bottom reefs such as Gray’s Reef and to Georgia’s coastline.

Georgia Southern University invites educators to replicate the drifter study and has developed an instructional video and guide for future drifter deployments.
