attribute NC_GLOBAL acquisition_description String Methodology as described in Holcomb et al. (2013):\n \nColonies of the temperate scleractinian coral Astrangia poculata were\ncollected and processed as previously described. Newly settled polyps and\ntheir associated substratum were attached to slides. The slides with corals\nwere suspended vertically in a flow-through aquarium receiving 20 micrometers\nfiltered Vineyard Sound seawater. Corals experienced a temperature range of 14\nto 30 degrees C. Aquaria were aerated, and corals were maintained under these\nconditions for at least one month prior to use in experiments. A mixture of\nbrown and white colonies (zooxanthellate and azooxanthellate colonies) was\nused for all treatments.\n \nFor the marking experiments, corals were placed in pre-washed containers with\nlids containing ~800 ml of water from the source aquarium. Airstones were\nadded to each container and each container bubbled continuously. Containers\nwere held within a water bath with a temperature similar to that of the source\naquarium.\n \nBa 135 or Sr 86 isotope spikes (purchased as carbonate salts from Oak Ridge\nNational Lab) were used as markers in some incubations. See the \\\"[coral\ngrowth dye experiment](\\\\\"https://www.bco-dmo.org/dataset/489382\\\\\")\\\" dataset\nfor results from marking experiments using one of four dyes (alizarin,\nalizarin complexone, calcein, and oxytetracycline).\n \nThe isotope spike marking was carried out as part of long term growth\nexperiments (see Holcomb et al. 2010 and 2012). Six to sixteen corals were\nused in each of the isotope spike treatments. For marking with 86Sr, 60\nmicroliters of an 86Sr solution were added to ~800 ml seawater and the corals\nwere incubated for two days. Growth was estimated from changes in buoyant\nweight (per Holcomb et al., 2010) for the 5 months prior to and the month\nfollowing the isotope spike. Corals were held at one of two temperatures: ~19\nor ~26 degrees C throughout that six month period.\n \nSpikes with 135Ba were carried out in a flow-through aquarium system (see\nHolcomb et al., 2012). Each reservoir supplying water to individual aquaria\nwas spiked with 81 microliters of 135Ba solution per liter of seawater. The\naquaria received spiked seawater for two days, after which unspiked seawater\nwas added to the reservoir, diluting the spike. Buoyant weights were measured\nfor the two months prior and one month following isotope exposure using a\nSartorius G803S balance, and the aquaria were held at either 16 or 24 degrees\nC throughout this time.

attribute NC_GLOBAL project String OA Nutrition and Coral Calcification
attribute NC_GLOBAL projects_0_acronym String OA Nutrition and Coral Calcification
attribute NC_GLOBAL projects_0_description String The project description is a modification of the original NSF award abstract.\nThis research project is part of the larger NSF funded CRI-OA collaborative research initiative and was funded as an Ocean Acidification-Category 1, 2010 award. Over the course of this century, all tropical coral reef ecosystems, whether fringing heavily populated coastlines or lining remote islands and atolls, face unprecedented threat from ocean acidification caused by rising levels of atmospheric CO2. In many laboratory experiments conducted to date, calcium carbonate production (calcification) by scleractinian (stony) corals showed an inverse correlation to seawater saturation state OMEGAar), whether OMEGAar was manipulated by acid or CO2 addition. Based on these data, it is predicted that coral calcification rates could decline by up to 80% of modern values by the end of this century. A growing body of new experimental data however, suggests that the coral calcification response to ocean acidification may be less straightforward and a lot more variable than previously recognized. In at least 10 recent experiments including our own, 8 different tropical and temperate species reared under nutritionally-replete but significantly elevated CO2 conditions (780-1200 ppm, OMEAGar ~1.5-2), continued to calcify at rates comparable to conspecifics reared under ambient CO2. These experimental results are consistent with initial field data collected on reefs in the eastern Pacific and southern Oman, where corals today live and accrete their skeletons under conditions equivalent to 2X and 3X pre-industrial CO2. On these high CO2, high nutrient reefs (where nitrate concentrations typically exceed 2.5 micro-molar), coral growth rates rival, and sometimes even exceed, those of conspecifics in low CO2, oligotrophic reef environments.\nThe investigators propose that a coral's energetic status, tightly coupled to the availability of inorganic nutrients and/or food, is a key factor in the calcification response to CO2-induced ocean acidification. Their hypothesis, if confirmed by the proposed laboratory investigations, implies that predicted changes in coastal and open ocean nutrient concentrations over the course of this century, driven by both climate impacts on ocean stratification and by increased human activity in coastal regions, could play a critical role in exacerbating and in some areas, modulating the coral reef response to ocean acidification. This research program builds on the investigators initial results and observations. The planned laboratory experiments will test the hypothesis that: (1) The coral calcification response to ocean acidification is linked to the energetic status of the coral host. The relative contribution of symbiont photosynthesis and heterotrophic feeding to a coral's energetic status varies amongst species. Enhancing the energetic status of corals reared under high CO2, either by stimulating photosynthesis with inorganic nutrients or by direct heterotrophic feeding of the host lowers the sensitivity of calcification to decreased seawater OMEGAar; (2) A species-specific threshold CO2 level exists over which enhanced energetic status can no longer compensate for decreased OMEGAar of the external seawater. Similarly, we will test the hypothesis that a nutrient threshold exists over which nutrients become detrimental for calcification even under high CO2 conditions; and (3) Temperature-induced reduction of algal symbionts is one stressor that can reduce the energetic reserve of the coral host and exacerbate the calcification response to ocean acidification.\nThe investigator's initial findings highlight the critical importance of energetic status in the coral calcification response to ocean acidification. Verification of these findings in the laboratory, and identification of nutrient and CO2 thresholds for a range of species will have immediate, direct impact on predictions of reef resilience in a high CO2 world. The research project brings together a diverse group of expertise in coral biogeochemistry, chemical oceanography, molecular biology and coral reproductive ecology to focus on a problem that has enormous societal, economic and conservation relevance.
