Study provides new tool to monitor coral reef 'vital signs'
Date:3/17/2011

MIAMI March 17, 2010 -- University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science scientist Chris Langdon and colleagues developed a new tool to monitor coral reef vital signs. By accurately measuring their biological pulse, scientists can better assess how climate change and other ecological threats impact coral reef health worldwide.

During a March 2009 experiment at Cayo Enrique Reef in Puerto Rico, the team tested two new methods to monitor biological productivity. They compared a technique that measures changes in dissolved oxygen within a chamber that encloses an area of water above the reef with one that measures the flux of dissolved oxygen across the turbulent boundary layer above an unconfined portion of the seafloor.

By measuring dissolved oxygen production and consumption rates, scientists were able to monitor the balance between the production of new organic matter by the corals and algae and the consumption of that organic matter by the reef's heterotrophs, which are essential to assessing the health of coral reef ecosystems.

A combination of these methods is a valuable tool for assessing and studying the effects of climate change on coral reef health, according to the authors.

According to a recent analysis by the World Resources Institute, nearly 75 percent of the world's coral reefs are currently threatened by human activities and ecological disturbances, such as rising ocean temperatures, increased pollution, overfishing and ocean acidification.

Measurements of biological productivity have typically been made by tracing changes in dissolved oxygen in seawater as it passes over a reef. However, this is a labor intensive and difficult method, requiring repeated measurements. The new method opens up the possibility of making long-term, unattended, high-temporal resolution measurements of photosynthesis and respiration of coral reefs and any other benthic ecosystems.
