Types and Sources

Anything man-made, including litter and fishing gear, can become marine debris once lost or thrown into the marine environment. The most common materials that make up marine debris are plastics, glass, metal, paper, cloth, rubber, and wood.

Glass, metal, and rubber are similar to plastic in that they are used for a wide range of products. While they can be worn away-broken down into smaller and smaller fragments, they generally do not biodegrade entirely. As these materials are used commonly in our society, their occurrence as marine debris is overwhelming.

Plastics:

Plastics are used in many aspects of daily life and are a big part of our waste stream. Like many areas, plastics are the most frequent type of debris found on Jekyll Island beaches.

 What are microplastics?

Microplastics” are pieces of plastic that are less than 5mm long. Microplastics can come from larger pieces of plastic that have broken down over and over again. Or, microplastics can be manufactured. For example, pre-production industrial plastic pellets or plastic “micro-scrubbers” in face wash are considered microplastics.

Derelict Vessels:

Thousands of abandoned and derelict vessels litter ports, waterways and estuaries, creating a threat to navigation, recreation, and the environment.
