Caisson Gate Deployed On Deepwater Reef

 

June 12, 2020

Deployment Video

On June 8, Marine Fisheries Administration staff deployed a 150-foot long caisson gate on the Deepwater Reef site (pdf). It now rests in 125 feet of water and rises off the bottom 30 feet at the following coordinates:
38*58.300 x 074*10.900

A caisson gate is a barrier used to dam off the open end of a dry dock and is constructed of heavy gauge steel with several tons of ballast in the keel. The deployment is sponsored by The Sportfishing Fund, an organization dedicated to artificial reef building.

Deployments of caisson gates in 2019 occurred on the Atlantic City and Cape May reefs. Vessels and structures such as these, after being emptied of all machinery and fluids and thoroughly cleaned, are inspected by the U.S. Coast Guardand DEP before sinking. Due to the thickness and quality of steel used in their construction, staff expect the service life of this artificial reef to last more than 75 years. Artificial reef deployments become home to more than 150 marine organisms including black sea bass, tautog, summer flounder, lobsters, crabs, and mussels. They will surely also become prime destinations for SCUBA divers and anglers alike. *add picture * View a video of the deployment at .

Staff of New Jersey Marine Fisheries Administration is planning two deployments off the coast next week as part of the Artificial Reef Program.

The first deployment, a 150-foot long caisson gate, is scheduled for the morning of Monday, June 8, on the (pdf).

The second deployment is scheduled for 6:00 a.m. on Tuesday, June 9, at the Sandy Hook Reef site (pdf). The sinking of the 65-foot tugboat VINIK HUNTRESS is in memory of Hudson River Fishermen's Association past member Darren Cardinal. Sponsorship at Sandy Hook is being provided by the association and The Sportfishing Fund.

The vessel will rest near the following coordinates:
40* 21.50 x 073* 56.40

Vessels and structures such as these, after being emptied of all machinery and fluids and thoroughly cleaned, are inspected by the U.S. Coast Guard and DEP before sinking. Due to the thickness and quality of steel used in their construction, staff expect their service life on an artificial reef on the ocean floor for over 75 years.

Reef deployments are always subject to change due to weather and sea conditions.
