CIOERT workshop on ocean acidification instrumentation and research needs

SRI International, Marine Technology Division, St. Petersburg FL

INVITATION/PURPOSE:

Title: New Instrumentation for Assessment of OA in Coral Ecosystems, and Modeling of Coral Calcification

Purpose:
Much of the effort to date to develop instruments to study the process and progression of ocean acidification (OA) has been aimed towards high precision and sensitivity instruments designed to measure small changes in SW chemistry in low variability oceanic waters (e.g. MAP-CO2, MICA, SAMI, SEAS, several mass specs, etc). These efforts have been accomplished with only minor coordination by a number of investigators at academic, R&D and NOAA institutions, and with substantial funding by NSF, NOAA and other federal agencies. In spite of such effort, much remains to be done to produce instruments that are reliable and robust enough for prolonged deployments. Coral reef ecosystems are one of the most vulnerable to OA but also the most complex to understand in terms of biotic/seawater interactions. Large biomass of organisms on/within coral reefs respire (adding to localized OA), photosynthesize (potentially counteracting OA), and calcify at various rates in various sub-habitats creating a complex patchwork of interactions between metabolism and bulk ocean water chemistry that the calcifying organisms live within and have to deal with on a daily basis. As a result of this biotic metabolism, coral reef seawater chemistry is highly variable over short time and spatial scales, and thus the instruments needed to study effects of OA on coral reef systems may have different specifications that those needed for oceanic studies. For both ecosystems, an integrated, autonomous instrument package is needed that measures at least two of the seawater carbonate parameters, and preferably three of them. The 3 day workshop will be held to critically review the instrumentation needs and specifications of various types of OA research especially for coral reefs, strengths and weaknesses of existing technologies, on-going developments, and funding needs which would allow integration into an instrument suite applicable to mid to long term deployment on coral reefs.



Concurrent with the instrument development efforts, a group of physiologists and cell biologists working on the mechanisms of coral calcification, ion transport and acid-base regulation will be meeting to develop an up-to-date mechanistic model of coral calcification, to identify the major information needs in order to predict coral calcification responses to OA. Coral reef ecosystems are one of the most vulnerable to OA but also the most complex to understand in terms of biotic/seawater interactions. Large biomass of organisms on/within coral reefs respire (adding to localized OA), photosynthesize (potentially counteracting OA), and calcify at various rates in various sub-habitats creating a complex patchwork of interactions between metabolism and bulk ocean water chemistry that the calcifying organisms live within and have to deal with on a daily basis. Thus corals may have evolved mechanisms to cope productively with moderate levels of acidification.
