attribute	NC_GLOBAL	acquisition_description	String	Plocamium cartilagineum was collected from Catalina Island in June - Nov. 2014 and Jan. 2015. Culture pots were placed in large thermally insulated coolers in a temperature-controlled water bath at either 15 or 20\u00b0C under saturating illumination of ~150 \u00b5moles photons/m^2/s. pCO2 treatments were supplied to closed culture pots by use of a gas mixing system combining Nitrogen, Oxygen and Carbon Dioxide to specific CO2 partial pressures, 20.9% oxygen and the balance being Nitrogen. Tissue samples were dried for 24 hours at 60\u00b0C. Dried samples were prepared for analysis by homogenizing samples using a metal laboratory scoop, cleaned with ethanol between each sample, which resulted in a fine power. Then, approximately 3 mg of the Plocamium cartilagineum tissue powder was measured, using an analytical balance, into a tin capsule and carefully enclosed with cleaned forceps. The tin capsules were put into 96-well trays and sent to the University of California, Davis Stable Isotope Facility (UCD- SIF). The samples were analyzed for delta-15N and delta-13C using the elemental analysis \u2013 isotope ratio mass spectrometry technique, which also provides results for tissue C and N content. Note: Trial 1 was a pilot test of culture system and methodological procedures so was not used for data collection in the testing of hypotheses. See Supplemental Files for a table of culture conditions for each of the 8 trials (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.
