CISME: NEW TECHNOLOGY DEVELOPMENT TO MEASURE CORAL IN SITU METABOLISM

Tools to non-destructively measure coral bioenegetics in situ are needed to promote rapid assessment and monitoring of metabolic health of corals and other benthic organisms affected by ocean acidification, global warming, and other anthropogenic effects. Non-destructive tools are especially needed for reef corals because their live cover is greatly reduced. CISME (Coral In Situ Metabolism and Energetics, pronounced “KISS ME” to reflect gentle interactions between the instrument and the coral) is such an instrument, that measures oxygen flux and delta pH that can be used to measure respiration, and photosynthesis rates of corals and other marine organisms. Laboratory and field tests show that the instrument produces quick, consistent metabolic measurements, as well as photosynthesis vs irradiance response curves. The instrument has a sample port for introducing reagents (e.g. CO2 enriched seawater) or withdrawing samples for analytes that require discrete samples (e.g. total alkalinity for calcification rates). These features make CISME suitable for ocean acidification research. The resulting technology will enhance how we assess coral reef ecosystem health beyond the information yielded by traditional visual surveys.
