ADVs and the Gulf of Mexico

Posted Thu, 01/26/2017 - 10:30

Abandoned and derelict vessels (ADVs) are a type of large marine debris that is a problem throughout the country. ADVs can be aesthetically unappealing, but can also create real problems by damaging important habitat, creating hazards to navigation and recreation, leaking pollutants into the environment, and impacting fisheries resources. Vessels can become derelict in a variety of ways, such as being abandoned by their owner after acquiring damage or sunk during a severe storm. Unfortunately, this type of debris can be extremely difficult and costly to remove, often making it difficult to address.

ADVs are particularly a problem in the Gulf of Mexico, especially due to the many severe storms in this region. ADVs and dilapidated docks remain along numerous rivers and tributaries that drain into the Gulf of Mexico. Many of these debris items are a direct result of storms including Hurricanes Ivan in 2004, Katrina and Rita in 2005, Ike in 2008, and Isaac in 2012. Unfortunately, this effect of these storms is not fully understood by many and it is an all too common practice in this region for boat owners to anchor their vessels in river systems prior to hurricane landfalls. Those boats can then lose their moorings and drift into marshes and stream banks from the strong winds, currents, and flooding that accompany these storms.

To address this problem in the Gulf region, the NOAA Marine Debris Program (MDP) has funded projects specifically to remove ADVs, including efforts in Dog River and Bayou la Batre, Alabama. Currently, the MDP is funding a project in Galveston Bay, Texas to remove large debris items such as ADVs. Unfortunately, there are still many ADVs that the MDP is not able to address due to costs and removal difficulties. For this reason, the MDP created the ADV InfoHub, which details how to address ADVs and provides avenues for removal in each coastal state. The ADV InfoHub also contains case studies and law reviews available for all Gulf States. In addition, the MDP has been involved in the creation of incident waterway response guides in both Florida and Alabama. These guides are meant to improve preparedness for response to and recovery from severe marine debris events by outlining existing responsibilities and procedures in one document for easy reference.
