Annual Data Summary
Summary of Reef Materials Deployed through 2002

Initial Construction

concrete

The following report summarizes reef construction activities on New Jersey's fourteen artificial reef sites. Between 1973 and 1983, materials were deployed by a private group, called the "Artificial Reef Committee", working in cooperation with the Sandy Hook Lab of the National Marine Fisheries Service. During that time, the Committee deployed seven vessels, encompassing 17,213 cubic yards, and 400 cubic yards of steel drums on the Sea Girt Reef ( Table 1. )

Number of Deployments

In 1984, the New Jersey Division of Fish and Wildlife took over all reef-building efforts in the state. Since the inception of the Division's program, reef construction has increased steadily ( Table 1. ) In 19 years, a total of 2,093 "patch" reefs were constructed. A patch reef is a several-square-yard to several-acre reef created by placing a vessel or army tank or barge-load of other material on the seafloor. About 13 percent of these reefs, 271 in number, were made in 2002.

Volume of Materials

concrete side-scan

During 2002, a total of 658,438 cubic yards of material was deployed on reef sites ( Table 1 ) including 634,176 cubic yards of rock, 11,830 cubic yards of concrete, 10,389 cubic yards of vessels, 1,018 cubic yards of concrete castings, 883 cubic yards of Reef Balls and 142 cubic yards of ocean cable. Over the last 19 years, a total of 3,301,892 cubic yards of material has been deployed on New Jersey's 14 reef sites, including 2,700,393 cubic yards of rock, 285,459 cubic yards of vessels, 229,365 cubic yards of concrete, 61,772 cubic yards of concrete-ballasted tire units and 17,853 cubic yards of obsolete army tanks. The distribution of material by reef site is shown in Table 2.

Tire Reef Program

The total production of concrete-ballasted tire units was 55,713 units during the 15-year cooperative tire reef program ( Table 4. ) the use of concrete-ballasted tire units was discontinued in 1998.

REEFEX

REEFEX began in 1994 as a joint military-civilian training program whereby the U.S. Navy, Coast Guard, Army and Navy Special Forces, Air Force, and New Jersey Army National Guard participated in providing obsolete military vehicles for reef construction activities. Tanks were cleaned and prepared at Fort Dix by the New Jersey Army National Guard. During the 6-year program, a total of 397 obsolete army vehicles were placed on 11 reef sites. The program ended in 1999 due to insufficient funding.

REEFEX

Reef Ball Habitats

In 1998, 16 fiberglass molds were purchased to fabricate concrete Reef Ball habitats. In 1999, construction of habitats began at Southern State Correctional Facility using inmate laborers. The program is designed to produce 700 habitats each year. Transportation of the habitats to ocean reef sites was provided by the Ocean County Bridge Department and now, by a contractor. In 2002, 650 habitats were placed on 5 reef sites. To date, a total of 2,556 Reef Ball habitats have been placed on 6 reef sites ( Table 4. )

Concrete Castings

Concrete castings is a new category of reef material in 2002. Concrete castings are pipes, junction boxes, and other hollow concrete structures with manufacturer's defects, like chips or cracks, that render them unsaleable. In 2002, 447 concrete castings were placed on two reef sites: Little Egg and Cape May.

Sea Floor Coverage

The seafloor coverage by reef structure is an important measurement of habitat for demersal fish and shellfish. The total area of seafloor that has been covered by reef materials over the past 19 years is 1,887,159 square yards ( Table 3. ) Rock, concrete and concrete-ballasted tire units provide the majority of the surface coverage due to their low height. The high relief of ships leads to large volumes, but low footprint coverage.

Reef Balls

Material Relief

The majority of material in terms of footprint ( area of seafloor covered ) has been moderately low ( 4-7' ) and low ( 0'-3' ) structures, with smaller amounts of moderately high ( 8'-12' ) and high profile ( over 12' ) structures. While the aim of the reef project is to create low profile structure that provides the greatest benefits for targeted reef species, such as sea bass, tautog, scup, and red hake, a mix that includes high profile material provides habitat for pelagic species, such as bluefish, bonito, jacks, and various baitfish. It should be noted that the lower portions of high profile structures also provide low profile habitat.

Vessels

Since 1973, a total of 122 vessels ( Table 5 ) have been sunk, with 115 by the Division of Fish and Wildlife. The vessels range in size from a 31-foot steel sport boat to a 460-foot Navy attack cargo transport. The Sea Girt, Garden State North, Atlantic City, and Cape May reefs have received the largest numbers of vessels ( Table 5. )

The vessels sunk during 2002 include:

  • Wedding Barge ( 109' deck barge )
  • Tuna Sub ( 42' deck barge )
  • Southwick's Barge ( 62' deck barge )
  • BassBarn.com ( 224' tanker barge )
  • Capt. Walt Hendee ( 244' tanker )

Reef Site Coverage

New Jersey's fourteen reef sites comprise over 99 million square yards of seafloor ( Table 14. ) By the end of 2002, the area of seafloor covered by all materials deployed on reef sites amounted to 1,887,159 square yards. Thus, reef material is now covering only about 1.90 percent of the state's 14 reef sites; 98.10 percent of the ocean bottom on these sites is still not covered with reef structure but remains as sand.
