attribute NC_GLOBAL acquisition_description String Samples were collected at 0 (initial) and 24 hours and parameters of carbonate\nchemistry were measured (DIC,CO2, HCO3,CO3-described below). pH drift assay\nexperiments consisted of 2 independent variables; inhibitor treatment and\nalgal presence, with 4 and 2 levels, respectively for each independent\nvariable. The inhibitor treatments included: seawater only (control),\nAcetazolamide (A), 4,4\\u2019-Diisothiocyano-2,2\\u2019-stilbenedisulfonic acid\n(DIDS), and Ethoxyzolamide (E). Algae were either present or absent (control)\nin a vial. Two replicate water samples were collected from each of 10\nexperimental culture pots of algae grown for 3 weeks at different combinations\nof average and standard deviations of pCO2 level during each of 3 experimental\ntrials and assayed after 24 hours with or without the presence of Ulva and\ncombinations of inhibitor treatments. In addition, 3 different levels of pCO2\nin seawater generated independently of the seawater in algal culture that\nrepresented the range of pCO2 levels assayed across the entire experiment were\nassayed over the same 24 hour period.\n \nCarbonate chemistry parameters were measured by sampling pH and total\nalkalinity (TA) of water samples. pH was determined using the m-cresol\nindicator dye method in a spectrophotometer (Dickson et al. 2007). TA samples\nwere analyzed by potentiometric titration coupled to a pH electrode calibrated\nusing certified reference material (CRM) from the Dickson laboratory at\nScripps Oceanographic Institute and the pH electrode calibrated using TRIS\nbuffer (Dickson et al. 2007). TA and carbonate parameters were calculated from\npotentiometric titration data and spectrophotometric pH data.

attribute NC_GLOBAL projects_0_description String Benthic macroalgae contribute to intensely productive near shore  ecosystems and little is known about the potential effects of ocean  acidification on non-calcifying macroalgae. Kübler and Dudgeon will test  hypotheses about two macroalgae, Ulva spp. and Plocamium cartilagineum,  which, for different reasons, are hypothesized to be more productive  and undergo ecological expansions under predicted changes in ocean  chemistry. They have designed laboratory culture-based experiments to  quantify the scope for response to ocean acidification in Plocamium,  which relies solely on diffusive uptake of CO2, and populations of Ulva  spp., which have an inducible concentrating mechanism (CCM). The  investigators will culture these algae in media equilibrated at 8  different pCO2 levels ranging from 380 to 940 ppm to address three key  hypotheses. The first is that macroalgae (such as Plocamium  cartilagineum) that are not able to acquire inorganic carbon in changed  form will benefit, in terms of photosynthetic and growth rates, from  ocean acidification. There is little existing data to support this  common assumption. The second hypothesis is that enhanced growth of Ulva  sp. under OA will result from the energetic savings from down  regulating the CCM, rather than from enhanced photosynthesis per se.  Their approach will detect existing genetic variation for adaptive  plasticity. The third key hypothesis to be addressed in short-term  culture experiments is that there will be a significant interaction  between ocean acidification and nitrogen limited growth of Ulva spp.,  which are indicator species of eutrophication. Kübler and Dudgeon will  be able to quantify the individual effects of ocean acidification and  nitrogenous nutrient addition on Ulva spp. and also, the synergistic  effects, which will inevitably apply in many highly productive, shallow  coastal areas. The three hypotheses being addressed have been broadly  identified as urgent needs in our growing understanding of the impacts  of ocean acidification.
