Productivity model CO2 diffusion Dataset Description: <p>This dataset represents calculations from a model of photosynthesis by diffusive uptake of only CO2 given expected abundance of carbonate chemistry parameters in ocean water of known temperature salinity and depth.&nbsp;</p> Methods and Sampling: <p>Expected values of carbonate chemistry in seawater of specified conditions were calculated using CO2Calc (Robbins et al. 2010). Estimates of photosynthetic responses of CO2-using red algae under specified conditions of light intensity, temperature and pCO2 were made using published data on rates of photosynthesis as functions of light intensity and temperature and the predicted availability and diffusive uptake rate of CO2 at the plant surface in seawater. Pathlength of diffusion of CO2 from seawater to the site of carbon fixation was assumed to be 20 microns for these data representing photosynthetic rates (See Kübler and Dudgeon 2015).

Science, Engineering and Education for Sustainability NSF-Wide Investment (SEES): Ocean Acidification (formerly CRI-OA)
NSF Climate Research Investment (CRI) activities that were initiated in 2010 are now included under Science, Engineering and Education for Sustainability NSF-Wide Investment (SEES). SEES is a portfolio of activities that highlights NSF's unique role in helping society address the challenge(s) of achieving sustainability. Detailed information about the SEES program is available from NSF (https://www.nsf.gov/funding/pgm_summ.jsp?pims_id=504707).
In recognition of the need for basic research concerning the nature, extent and impact of ocean acidification on oceanic environments in the past, present and future, the goal of the SEES: OA program is to understand (a) the chemistry and physical chemistry of ocean acidification; (b) how ocean acidification interacts with processes at the organismal level; and (c) how the earth system history informs our understanding of the effects of ocean acidification on the present day and future ocean.

Ocean Acidification: Scope for Resilience to Ocean Acidification in Macroalgae
https://osprey.bco-dmo.org/project/2275
Ocean Acidification: Scope for Resilience to Ocean Acidification in Macroalgae
<p>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, <em>Ulva</em> spp. and <em>Plocamium cartilagineum</em>, 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 <em>Plocamium</em>, which relies solely on diffusive uptake of CO2, and populations of<em> Ulva</em> 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<em> Ulva</em> 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 <em>Ulva</em> 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.</p>
