International Workshop on Cold-Water Corals Held in Norway

If someone asked you to name a country with a lot of corals, you'd expect tropical answers like "Australia" or "Belize" because of their well-known barrier reefs. Norway, crossed by the frigid Arctic Circle, would probably not even make the top 10 guesses. In fact, Norwegian waters are home to large numbers and varieties of cold-water corals. These corals, including both stony corals and seafan-like soft corals, do not host photosynthetic algae and so can survive in dark, deep waters. For that reason, they are also known as deep-sea corals. However, they may be found as shallow as 40 m in Norwegian fjords and as deep as thousands of meters on seamounts and on the continental shelf. As in the Gulf of Mexico, the areas of hard bottom where these corals are found are commonly areas of interest for oil and gas exploration and drilling.

The first Norwegian-hosted workshop on cold-water corals was sponsored by the Norwegian Oil and Gas Association (OLF) and hosted by the International Research Institute of Stavanger (IRIS) on May 31-June 1, 2010. This workshop was designed to bring together researchers, government and nongovernmental organizations, and representatives from the oil and gas industry who are actively involved in cold-water-coral research and management. (See workshop Web site.) Christina Kellogg of the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, was the only invited speaker and attendee from the United States. Kellogg was invited to speak specifically because of her knowledge of coral-associated microbial communities and how they can be used as diagnostics of coral stress (see related article, "Coral Paparazzi," this issue). Other scientific experts attended from Australia, Brazil, Canada, Germany, the Netherlands, Norway, Sweden, and the United Kingdom, with the goal of sharing results and expertise from national and international research projects. The workshop focused on establishing the current state of knowledge about the sensitivity of cold-water corals to oil and gas activities and on promoting discussions about management measures needed to protect cold-water-coral habitats.
