It was 60 levels final December when two 55,000-pound MARTA railcars slowly inched off a barge east of Ossabao Island. The 72-foot-tall behemoths, which for many years have shuttled thousands and thousands of Atlantans across the metropolis, emerge like hesitant swimmers within the chilly, roaring water. After which they tipped and disappeared, sinking 60 ft to the ocean flooring.
The automobiles have been the newest addition to Georgia’s Offshore Synthetic Reef (OAR) program, which started in 1970 and is at the moment managed by the Georgia Division of Pure Sources’ Coastal Sources. Over the previous half century, the state has constructed inland and offshore reefs product of numerous repurposed gadgets: outdated battle tanks, items of bridges, concrete tetrapods and pallet balls, plus tugboat components, pipes, pilings and even hen coops. After decommissioning eight Tactical Aircrew Fight Coaching System towers, which have been as soon as used to coach pilots, the state’s Division of Protection contributed them to the trigger and their “legs” have already turned to the wall. In a full-circle second, the 100-ton bronze propeller from the notorious Golden Ray cargo ship, which sank in St. Simons Sound in 2019, has additionally been donated as a mural.
The OAR mission, which covers greater than 116 sq. miles of ocean, consists of 20 offshore reefs, not counting the coaching towers. A few of these reefs are constructed as much as 70 miles offshore, whereas two close by seaside reefs are constructed for anglers in small boats. One would possibly surprise why we want this synthetic reef: it’s just because there are only a few pure reefs in Georgia. Grey’s Reef Nationwide Marine Sanctuary, 19 miles east of Sapelo Island, is a notable exception with greater than 200 species of fish. However Georgia’s coastal sea flooring is usually shale and sand, extending 80 miles earlier than it meets the Gulf Stream; Solely 5 % of the sport incorporates appropriate habitat for fish. “Every of our reef areas is 2 by 2 sq. nautical miles,” explains marine biologist Paul Meaders, chief of the DNR’s Coastal Sources Division’s Synthetic Reef, Habitat Restoration and Boating Entry Unit. It’s a large quantity of ocean house. “We may put stuff in each ‘field’ on that wall for one more hundred years and never come near filling these areas.”

Synthetic reefs entice greater than 1 / 4 of one million leisure anglers a 12 months and usher in $220 million a 12 months immediately, in addition to a whole bunch of thousands and thousands extra by means of transportation, meals, resort and different tourism spending. “It is very nice to have these reefs,” explains Josh Cook dinner, co-owner together with angler Richie Lott of Georgia Sport Fishing Charters. “Initially there was a desert within the sea they usually established an oasis there.”
Thomas Worthy, rapid previous chairman of the board at MARTA, spearheaded the car-to-reefs mission after assembly former DNR Commissioner Mark Williams at a social occasion. “I launched him, and he mentioned, ‘I need all of your outdated automobiles,'” Worthy mentioned. “I mentioned, ‘What are you speaking about?'” However after Williams defined the historical past of the reef program, Worthy was a convert. “It was the appropriate time for us,” he says. Over the subsequent decade, all the MARTA fleet can be upgraded with 224 new, state-of-the-art automobiles and the older fleet can be regularly retired. In 2022, the MARTA Board of Administrators permitted a plan to ship eight of the company’s decommissioned automobiles to the DNR. Vehicles are completely cleaned and stripped of any hazardous supplies or contaminants earlier than being taken ashore. The 2 automobiles deposited in December have been the primary to go.
By means of the creative energy of nature itself, this metallic “trash” is quickly lined by a powerful outcropping of soppy corals, sponges, and different organisms, which inside 5 years are half a foot thick. Small baitfish make the reefs their dwelling, and shortly, massive sport fish, turtles, and different marine creatures observe, populating each protecting nook, cranny, and crevice. Georgia’s temperate local weather and comparatively easy waters fill synthetic reefs with beautiful biodiversity: “The primary time I dove into them, I could not imagine how lovely these reefs have been,” says Daniel Gleason, a marine ecologist at Georgia Southern College. “Variety Challenges Pure Coral Reefs.”
