USCG Massachusetts Artificial Reef Addition

The U.S. Coast Guard recently dropped more than 140,000 pounds of obsolete concrete buoy sinkers on an artificial reef near Yarmouth, Massachusetts.

Used to anchor buoys in place, concrete sinkers come in a variety of sizes and weights, from 100 pounds to 20,000 pounds.

U.S. Coast Guard Cutter Oak (WLB-211) and Aids to Navigation Team (ANT) Woods Hole, Massachusetts, used the discontinued concrete sinkers to support the Massachusetts Division of Marine Fisheries (DMF) artificial reef program.

Lt. Dan Miller, the executive officer of the Newport, Rhode Island-based Coast Guard Cutter Oak, said the artificial reef operation gave crewmembers the chance to complete training and annual weight testing of the buoy handling gear.

Coast Guardsmen deployed the concrete sinkers across a one-acre area of the artificial reef. The program is a valuable resource for commercial and recreational fishermen to cultivate sustainable fisheries, said Miller.

The artificial reef “provides desirable habitat for finfish and lobsters in an otherwise featureless area.” according to Mark Rousseau from the Massachusetts Division of Marine Fisheries.
“Artificial reefs enhance habitat by providing structures in structure-limited areas,” said  “We expect to see reef associated fish occupying the area around the deployed material by next year.”

Commercial and recreational fisheries support more than 97,000 jobs in Massachusetts, according to a National Oceanic and Atmospheric Administration (NOAA) report on Fisheries Economics in the U.S.

The 128-acre artificial reef was developed in 1978. Until the recent addition of concrete buoy anchors, the reef was lacking structure necessary to attract and sustain a variety of fish species.

Senior Chief Petty Officer Manuel Gonzales, the officer-in-charge of Aids to Navigation Team (ANT) Woods Hole, Massachusetts, said his team jumped at the opportunity to participate in the operation.

“At the ANT, we use 1,000 to 4,000 pound sinkers,” said Gonzales. “When they start to show extreme signs of wear in the concrete or on the bails that attach the chain, they are replaced.”

From the U.S.-Canadian border to Buzzards Bay and Nantucket, Massachusetts, U.S. Coast Guard Cutter Oak maintains 144 Aids to Navigation (ATON) and supports a wide variety of other missions. The seagoing buoy tender services buoys and beacons that guide ships into Boston; Portsmouth, New Hampshire; and Portland, Maine.

ANT Woods Hole services more than 232 buoys, 72 beacons and approximately 1,100 Private ATON from the Cape Cod Bay to Nantucket and Martha's Vineyard.

The U.S. Coast Guard maintains more than 48,000 ATON across more than 25,000 miles of navigable American waterways that facilitate the safe movement of millions of mariners and trillions of dollars of trade every year.

Rousseau from the Division of Marine Fisheries said the buoy sinker operation was the first of what he hoped would be many collaborative efforts with the Coast Guard to support artificial reefs.
