  • These data were generated from a one-time experiment in support of a coral ecophysiology manuscript; published in Marine Biology. Edmunds (2012) Marine Biology 159: 2149-2160 doi:10.1007/s00227-012-2001-y The hypothesis that was tested stated that high pCO2 (76.6 Pa and 87.2 Pa vs. 42.9 Pa) has no effect on the metabolism of juvenile massive Porites spp. after 11 days at 28 °C and 545 lmol quanta m-2 s-1. The response was assessed as aerobic dark respiration, skeletal weight (i.e., calcification), biomass, and chlorophyll fluorescence. Corals were collected from the shallow (3–4 m) back reef of Moorea, French Polynesia (17°28.6140 S, 149°48.9170 W), and experiments conducted during April and May 2011. An increase in pCO2 to 76.6 Pa had no effect on any dependent variable, but 87.2 Pa pCO2 reduced area-normalized (but not biomass-normalized) respiration 36 %, as well as maximum photochemical efficiency (Fv/Fm) of open RCIIs and effective photochemical efficiency of RCIIs in actinic light (DF/Fm0 ); neither biomass, calcification, nor the energy expenditure coincident with calcification (J g-1) was effected. These results do not support the hypothesis that high pCO2 reduces coral calcification through increased metabolic costs and, instead, suggest that high pCO2 causes metabolic depression and photochemical impairment similar to that associated with bleaching. Evidence of a pCO2 threshold between 76.6 and 87.2 Pa for inhibitory effects on respiration and photochemistry deserves further attention as it might signal the presence of unpredictable effects of rising pCO2.

  • Data collected under the auspices of the MCR LTER are available to the public after primary publication, or at most two years after the completion of the study unless proprietary restrictions are warranted. Use of MCR LTER data is subject to acceptance of the following conditions: 1. The user agrees to provide valid name and contact information prior to downloading online data. This information will be used to contact the user in case of changes to the data, and may also be used by data set authors and MCR LTER project administrators to document data usage. 2. The user agrees to cite the data set author and MCR LTER in all publications in which the data are used, as per the instructions in the data documentation. If no specific instructions are provided in the data documentation, the user is requested to include the following statement: "Data sets were provided by the Moorea Coral Reef Ecosystem LTER, funded by the US National Science Foundation (OCE-0417412)." 3. The user agrees to provide one copy of any manuscript based on MCR LTER data to the data set author prior to submitting it for publication. 4. The user agrees to send two hard copies of any published manuscript based on MCR LTER data to the following address: Dr. Andrew J. Brooks Deputy Program Director, MCR LTER Marine Science Institute University of California Santa Barbara, CA 93106-6150 The user also agrees to send one electronic copy (pdf format) to the following e-mail address: 5. Users are prohibited from selling or redistributing any data provided by MCR LTER without explicit prior permission. 6. Users are encouraged to contact original investigators responsible for data. Where appropriate, researchers whose projects are integrally dependent on MCR LTER data are encouraged to consider collaboration and/or co-authorship with original investigators. 7. Extensive efforts are made to ensure that online data are accurate and up to date, but the authors and the MCR LTER will not take responsibility for any errors that may exist in data provided online. Furthermore, the user assumes all responsibility for errors in analysis or judgment resulting from use of the data. 8. Any violation of the terms of this agreement will result in immediate forfeiture of the data and loss of access privileges to other MCR LTER data sets.
