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 \nTissue samples were dried for 24 hours at 60\\u00b0C. Dried samples were\nprepared for analysis by homogenizing samples using a metal laboratory scoop,\ncleaned with ethanol between each sample, which resulted in a fine power.\nThen, approximately 3 mg of the Plocamium cartilagineum tissue powder was\nmeasured, using an analytical balance, into a tin capsule and carefully\nenclosed with cleaned forceps. The tin capsules were put into 96-well trays\nand sent to the University of California, Davis Stable Isotope Facility (UCD-\nSIF). The samples were analyzed for delta-15N and delta-13C using the\nelemental analysis \\u2013 isotope ratio mass spectrometry technique, which\nalso provides results for tissue C and N content.\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.
