attribute	NC_GLOBAL	acquisition_description	String	Ulva was collected prior to each trial in May, June and July 2015 near Malibu, CA (34\u00b004'12\"N 118\u00b056'69\"W) Culture pots were placed in large thermally insulated coolers in a temperature-controlled water bath at 15\u00b0 C under saturating illumination of ~550 \u00b5moles photons/m^2/s on a 12:12 L:D cycle. 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. In situ probes in each culture pot monitored pH and temperature every 10 minutes by sampling and logging values to an Excel spreadsheet to track the dynamics of both variables.

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.
