Joint US/Japanese Aquarius mission to conduct in situ measurements of coral metabolism: A comparison across oceans. PROJECT SUMMARY Coral reefs contribute substantially to the productivity of coastal ecosystems in many tropical and subtropical countries. Detailed studies of coral productivity combined with measurements of coral biomass are not common. Together, productivity and biomass data can be used to understand the role coral reefs play in the global carbon cycle, which is critical to understanding factors related to global climate change and the chemistry of the ocean. This project is important because it takes a comparative approach across different oceans, using similar techniques and protocols to study coral reefs. It represents the first cooperative program between NOAA and JAMSTEC using saturation diving. Aquarius will be used for its extended diving capabilities and ability to conduct experiments using sophisticated electronics and data collection techniques. Specifically, the Japanese (from JAMSTEC, Japan Marine Science and Technology Center) and U.S. team will: 1. Measure primary production (using underwater respirometers) of major coral species; 2. Measure specific parameters associated with coral photosynthesis using specially built light measurement devices; and 3. Measure environmental conditions at the site, short- and long-term. JAMSTEC is currently conducting a major coral reef program, The Coral Ecosystem Quantitative Measurement Project, at Sekisei Lagoon. Biomass data for the coral ecosystem (using corals phytoplankton, zooplankton, algae, and fishes) is collected periodically and is being used to develop bio-indicators to monitor environmental change. Data also contributes to several international coral reef monitoring programs, including the International Coral Reef Initiative (ICRI) and the Global Coral Monitoring Network (GCRMN). The primary goals for New England Aquarium staff will be to support the Japanese science project. After that commitment has been met, Stone and Mallory will: 1) Test a new shark repellent and pneumatic delivery system. 2) Document feeding (and other) behaviors of reef animals and the condition of corals (particularly bleached coral) with digital video and still photography. 3) Gather photographs and information for children's book on the Aquarius habitat. 4) Gather other information for magazine articles, exhibits, and other education al outreach materials for The New England Aquarium and other aquariums. 5) Create half hour TV documentary with the National Geographic Society. |
