Coral Reef Monitoring

What Is Coral Reef Monitoring?

Monitoring is the gathering of data and information on coral reef ecosystems or on those people who use coral reef resources. Monitoring should be repeated on a regular basis, preferably over an extended period of time. Coral reefs have natural changes occur over time; however, they are also affected by activities on land that add nutrients and sediments to the ocean, increase air pollution, and contribute to climate changes. Therefore, to observe these changes scientists and organizations record changes in coral cover, fish populations, species diversity, as well as coral bleaching and disease events.

How Reefs Are Commonly Monitored

     *Manta tow and timed swims
     *Transects
     *Quadrats
     *Photography and video
     *Roving dives

Benefits of Monitoring

Resource assessment and mapping, resource status and long-term trends, status and long-term trends of user groups, impacts of large-scale disturbances, impacts of human activities, performance evaluation & adaptive management, education and awareness raising, and contributing to regional and global networks.

Reef Monitoring Projects

The United States Virgin Islands Territorial Coral Reef Monitoring Program

The United States Virgin Islands Territorial Coral Reef Monitoring Program is one of the most important programs designed to monitor and track the status of the reefs in the US Virgin Islands. It is funded by NOAA's Coral Reef Conservation Program and administered by The Division of Coastal Zone Management under the USVI Department of Planning and Natural Resources Administration. They conduct an annual survey of the reefs within the US Virgin Islands.

Objectives: The objective of this program are to monitor and track the status of reefs and the inhabitants in areas around the US Virgin Islands; St. Thomas, St. John, and St. Croix. It also focuses on threats to reef systems such as pollution, overfishing, and thermal stress. They work closely to link changes in reef health with specific stressors and figure out the plan of action that would best preserve the reef and the fish communities. They also find ways to study threatened species as well as other components of the reef system that we know little information about.

Methodology/ Experimental Design:

Visual fish census
Belt transects
Roving dives
Fish counts

A Few Key Points From The 2011 Annual Report:

The Virgin Island National Park

The Virgin Island National Park is another active participant in the US Virgin Islands monitoring of coral reefs. They play a part by monitoring air quality, marker buoy instillations, and ongoing research on coral disease, sedimentation rates, fishery population biology, and watershed delineation.
