attribute	NC_GLOBAL	acquisition_description	String	Growth rate was measured in batch culture by pooling all plant thalli and summing them to attain the datum for the culture pot. Hence, the culture pot is the unit of replication. Growth rate was measured by recording the fresh weight of living material approximately every 6 days. Plant tissue was lightly stacked and gently pressed between layers of Kimwipes. This method reduced handling time and removed superficial water prior to weighing. The stack was then weighed together to attain the fresh weight for the pot. Relative growth rate was then calculated following L\u00fcning (1990):\u00a0 RGR(% . day-1 = (100*Ln(W2/W1))/(t2-t1), where W1, W2, t1, t2 correspond to fresh weights at times 1 (t1) and 2 (t2), respectively. The weekly relative growth rates track the dynamics of growth and its variation during the experiment. In addition to growth rates estimated approximately weekly, estimates of overall net and absolute growth rates integrated across the 3-week experiment were also made using the initial and final starting masses. The difference between the overall net and absolute growth rate estimates is that the latter estimate includes small tissue fragments derived from whole thalli that occasionally appeared at the end of a weekly growth interval, but were thought to not be healthy viable fragments that would generate new growth in the subsequent interval so were discarded at the beginning of the next growth interval. Note: Trial 1 was a pilot test of culture system and methodological procedures so was not used for data collection

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.
