Major storms such as Hurricanes Katrina and Rita are capable of inflicting severe damage on the coastal areas they impact, generating many thousands of cubic yards of debris and dispersing it on land, in canals and inshore waterways, in marshes and wetlands, and in offshore waters of the Gulf of Mexico. When deposited in coastal waters by the storm event, natural and human-made items become marine debris that can be invisible in the murky waters of the Gulf, making it difficult to locate, avoid, and remove. Unfortunately, becoming submerged and invisible does not render the debris items harmless. Marine debris can damage boats and fishing gear, cripple fishing operations, and prevent commercial and recreational activities in the areas affected. Removal of marine debris in shipping channels is addressed by existing regulations, in order to open these vital transportation and commerce routes as quickly as possible. Presently, however, there is no established mechanism to plan for, survey, and remove marine debris in areas outside of major shipping and navigation channels, and no existing guidelines to facilitate such a process. |
