attribute NC_GLOBAL acquisition_description String Plocamium cartilagineum was collected from Catalina Island in June - Nov. 2014\nand Jan. 2015.\n \nCulture pots were placed in large thermally insulated coolers in a\ntemperature-controlled water bath at either 15 or 20\\u00b0C under saturating\nillumination of ~150 \\u00b5moles photons/m^2/s. pCO2 treatments were supplied\nto closed culture pots by use of a gas mixing system combining Nitrogen,\nOxygen and Carbon Dioxide to specific CO2 partial pressures, 20.9% oxygen and\nthe balance being Nitrogen.\n \nAreal growth: Frond pieces were placed under glass without overlap of branches\nadjacent to a ruler for scale and imaged using an Infinity 2 camera with\nattached macro lens mounted on a copy stand. Images and calibrated and surface\narea of fronds measured using Image J. Measurements were taken at the start\nand end of the trial. For all measures of growth (by surface area\n[adj_growth], and biomass [growth_biom] and [growth_dyn]) the calculations are\nspecific growth rates, meaning LOG(measure@t2 / measure@t1)/(t2-t1).\\u00a0For\nsurface area measures (adj_growth) and biomass (as growth_biom), t1 is the\ninitial measure at the start of the experiment and t2 is the final measure at\nthe end of the experiment. For biomass (asgrowth_dyn), t1 is the measure at\nthe start of each weeklong interval and t2 is the measure at the end of the\ninterval. Thus, there were typically 3 such intervals during a trial in which\ngrowth was measured and the datum in the column growth_dyn represents the\naverage of those interval specific measures over the course of a trial.\n \nNote: Since tagging individual fronds compromised frond performance, all\nfronds in a culture pot were treated as sub-samples that were summed to give\nthe datum for the culture pot that was treated as the replicate.\n \nBiomass: Frond pieces were gently blotted dry with paper toweling to remove\nsurface water and weighed at weekly intervals to estimate biomass specific\ngrowth rates (growth_biom and growth_dyn). Note: since tagging individual\nfronds compromised frond performance, all fronds in a culture pot were treated\nas sub-samples that were summed to give the datum for the culture pot that was\ntreated as the replicate.\n \nNote: Trial 1 was a pilot test of culture system and methodological procedures\nso was not used for data collection in the testing of hypotheses.\n \nSee Supplemental Files for a table of culture conditions for each of the 8\ntrials (pdf).

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.
