A caisson gate, constructed off heavy gauge steel with several tons of ballast in the keel, is a barrier used to dam off the open end of a dry dock. The gates originated from the U.S. Navy and range in size from 110-140 feet long and roughly 30-40 feet high, with a width of 25 feet. The first deployment of a caisson gate occurred on the Atlantic City Reef in a "patch" reef now called the William Kane Reef in honor of the first New Jersey Artificial Reef Coordinator, William "Bill" Kane Figley.

Once the structure is fully flooded, it will have no more reason to remain upright and will fall over flat.

Glass & Ceramics

Delaware Water Gap Bottles

Glass is a hard substance, usually brittle and transparent, composed chiefly of silicates and an alkali fused at high temperature.

Composition and Properties of Glass

Most glass is a mixture of silica obtained from beds of fine sand or from pulverized sandstone; an alkali to lower the melting point, usually a form of soda or, for finer glass, potash; lime as a stabilizer; and cullet ( waste glass ) to assist in melting the mixture. The properties of glass are varied by adding other substances, commonly in the form of oxides, e.g., lead, for brilliance and weight; boron, for thermal and electrical resistance; barium, to increase the refractive index, as in optical glass; cerium, to absorb infrared rays; metallic oxides, to impart color; and manganese, for decolorizing.
