attribute	NC_GLOBAL	acquisition_description	String	Cultures:\u00a0Pleurochrysis\u00a0carterae\u00a0cultures were maintained in exponential growth phase under axenic conditions in semi-continuous batch culture using L1-Si media prepared on 0.2 um-filtered, UV-sterilized, autoclaved seawater.\u00a0 Cultures were acclimated to one of three\u00a0pCO2\u00a0treatments for > 9 generations before experiments were performed.\u00a0 Cultures were maintained in an incubator at 16.5 +/- 0.5 \u00a0degrees C and 470 umol photons/m-2/s\u00a0PAR on a 14-10 light-dark cycle where the lights turned on at 6 am and turned off at 8 pm. pCO2\u00a0Treatments: Carbonate chemistry was manipulated by bubbling cultures and prepared media with 500 mL/min\u00a0with 0.2 um-filtered 280, 380, or 750 ppm\u00a0pCO2\u00a0air.\u00a0 The\u00a0pCO2\u00a0levels of the treatment air were established using two mass flow controllers (Aalborg, Orangeburg, NY, USA) for each treatment to precisely mix in-house compressed air and pure CO2\u00a0(Maine Oxy, Auburn, ME, USA).\u00a0 The in-house compressed air was stripped of CO2\u00a0to less than 10 ppm CO2\u00a0using a Puregas VCD CO2\u00a0Adsorber (Puregas, LLC, Broomfield, CO, USA).\u00a0 The\u00a0pCO2\u00a0of the gas mixtures was stable to +/- 8 ppm.\u00a0\u00a0pCO2\u00a0values of the cultures may be different than the target levels due to biological activity. 24 h Culture Dynamics Monitoring:\u00a0 To understand the chemical and biological culture dynamics over a 24 h period, the investigators took measurements of one culture from each\u00a0pCO2\u00a0treatment every hour for 24 h.\u00a0 To reduce analytical costs, some parameters were not measured each hour (PIC, nutrients, total alkalinity).\u00a0 During the dark period, a red lamp was used to limit the light that might influence the cultures. \u00a0 pH Measurements:\u00a0 The pH of the cultures was measured using an OrionTM\u00a0ROSSTM\u00a0electrode connected to an Orion StarTM\u00a0A211 Benchtop pH meter (ThermoFisher Scientific, Waltham, MA, USA), calibrated with NBS buffers (EK Industries, Inc., Joliet, IL, USA) and corrected to the total scale using spectrophotometric pH measurements of culture samples.\u00a0 Spectrophotometric pH measurements of 0.2 um-filtered culture samples were made with 20 mM\u00a0m-Cresol purple sodium salt indicator dye (Alfa Aesar, Ward Hill, MA, USA) using a Hitachi U-3010 spectrophotometer (Hitachi High- Technologies, Clarksburg, MD, USA) equipped with a water circulated cell holder connected to a VWR 1160 water bath (VWR, Radnor, PA, USA) set at 16.5 degrees C, holding a 1 cm quartz cell.\u00a0 The method followed the procedure described by Clayton and Byrne (1993) and Dickson et al. (2007), using the refit equation of Liu et al. (2011), resulting in a resolution of +/-0.004 pH units. \u00a0 Temperature:\u00a0Temperature measurements were made with an OrionTM\u00a0ROSSTM\u00a0electrode connected to an Orion StarTM\u00a0A211 Benchtop pH meter (ThermoFisher Scientific, Waltham, MA, USA). Salinity:\u00a0 Salinity was measured using an Acorn SALT 6 handheld salinity meter (Oakton Instruments, Vernon Hills, IL, USA) with a resolution of +/- 0.1 ppt. in vivo Fluorescence:\u00a0 Fluoresence was measured using a Turner 10-AU fluorometer (Turner Designs, Sunnyvale, CA, USA). Cell density and cell diameter: Culture density and mean cell diameter were measured using a Moxi Z mini automated cell counter (ORFLO Technologies, Ketchum, ID, USA), which has a coefficient of variation of 4%. Particulate Inorganic Carbon:\u00a0 Bulk culture PIC analyses followed the technique of Fernandez et al. (1993): 10 mL culture samples were filtered onto 0.4 um polycarbonate filters and rinsed with potassium borate buffer with the pH adjusted to 8.0 to remove seawater calcium chloride.\u00a0 Filters were carefully moved to trace-metal free centrifuge tubes and digested with 5 mL of 5% nitric acid.\u00a0 The calcium concentration was measured using a Jobin Yvon Ultima C inductively coupled plasma-atomic emission spectrometer (ICP- AES, HORIBA, Ltd., Kyoto, Japan).\u00a0 Bulk culture PIC measurements were corrected to PIC/cell-1\u00a0using the corresponding cell density measurements. Nutrients (measured at University of California Santa Barbara):\u00a0 Culture samples were filtered to 0.2 um to remove all algal cells and coccoliths, and samples were frozen prior to analysis.\u00a0 Total N (nitrate + nitrite), nitrate, phosphate, and silicate were measured by Flow Injection Analysis at the University of California, Santa Barbara, Marine Science Institute\u2019s Analytical Lab using a QuikChem 8000 (Lachat Instruments, Loveland, CO, USA). Nutrients (measured by Bigelow Analytical Services):\u00a0 Culture samples were filtered to 0.2 um to remove all algal cells and coccoliths, and samples were frozen prior to analysis.\u00a0 Nitrate and phosphate were measured by Continuous Flow Analysis by Bigelow Analytical Services using a SEAL AutoAnalyzer 3 HR (SEAL Analytical Inc., Mequon, WI, USA). Total Alkalinity:\u00a0 Culture samples were filtered to 0.2 um to remove all algal cells and coccoliths.\u00a0 Total alkalinity was measured via titration with 0.01 N HCl using a Metrohm Titrando 888 controlled by Tiamo software (Metrohm, Riverview, FL, USA) to perform automated Gran titrations of 4 mL samples.\u00a0 Titrations were corrected to Certified Reference Materials (supplied by the laboratory of Andrew Dickson, Scripps Institution of Oceanography, La Jolla, CA, USA).

attribute	NC_GLOBAL	projects_0_description	String	(Extracted from the NSF award abstract) Ocean acidification is one of the most pressing marine science issues of our time, with potential biological impacts spanning all marine phyla and potential societal impacts affecting man's relationship to the sea. Rising levels of atmospheric pCO2 are increasing the acidity of the world oceans. It is generally held that average surface ocean pH has already declined by 0.1 pH units relative to the pre-industrial level (Orr et al., 2005), and is projected to decrease 0.3 to 0.46 units by the end of this century, depending on CO2 emission scenarios (Caldeira and Wickett, 2005). The overall goal of this research is to parameterize how changes in pCO2 levels could alter the biological and alkalinity pumps of the world ocean. Specifically, the direct and indirect effects of ocean acidification will be examined within a simple, controlled predator/prey system containing a single prey phytoplankton species (the coccolithophore, Emiliania huxleyi) and a single predator (the oceanic metazoan grazer, Calanus finmarchicus). The experiments are designed to elucidate both direct effects (i.e. effects of ocean acidification on the individual organisms only) and interactive effects (i.e. effects on the combined predator/prey system). Interactive experiments with phytoplankton prey and zooplankton predator are a critical starting point for predicting the overall impact of ocean acidification in marine ecosystems. To meet these goals, a state-of-the-art facility will be constructed with growth chambers that are calibrated and have highly-controlled pH and alkalinity levels. The strength of this approach lies in meticulous calibration and redundant measurements that will be made to ensure that conditions within the chambers are well described and tightly monitored for DIC levels. Growth and calcification rates in coccolithophores and the developmental rates, morphological and behavioral effects on copepods will be measured. The PIC and POC in the algae and the excreted fecal pellets will be monitored for changes in the PIC/POC ratio, a key parameter for modeling feedback mechanisms for rising pCO2 levels. In addition, 14C experiments are planned to measure calcification rates in coccolithophores and dissolution rates as a result of grazing. These key experiments will verify closure in the mass balance of PIC, allowing the determination of actual dissolution rates of PIC within the guts of copepod grazers.
