Shinnecock Artificial Reef

Shinnecock Artificial Reef (historical)

2.0 Nautical miles south of Shinnecock Inlet, 0.55 sq miles
Depth: 76 - 84 ft

Shinnecock Artificial Reef (now)

Shinnecock Reef was originally very small, but has been expanded greatly. The pink region is the historical area, and the blue region is the new deployment zone, while the full permitted size of the reef is a 1-nm square that encloses the deployment zone.

  • Asylum is described as a 60' steel vessel, sunk 2025.
  • "unknown" is described as a 46' steel hull pleasure craft, sunk 1987.

In the old version of the website, I had the names Marlu and Maroca recorded for this reef. When I got the new photos of most of the reefs, Maroca became apparent - it is spray-painted on the transom of the vessel. Marlu was harder, but I think I have that one figured out as well - New York lists it as a 70' vessel without a name. I also had a second drydock at Fire Island that I think belongs here. New York's reef program was moribund for so long that the records are unclear.

Reef site coordinates differ from NOAA Navigational Charts.

All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.




2016 Update

Well, computers, you can bet that everything has changed here.


software

There are a number of computer software packages available that allow you to simulate different dive profiles and create custom decompression tables without actually going in the water. Most of them have graphical interfaces, and allow you to vary not only the dive profile, but gas mixes, decompression mixes, decompression stops, algorithm, conservatism, and many other factors. Software like this is a staple in the technical diving field but is also useful to the recreational diver. Here are a couple, with links:
