attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Cultures:\u00a0Pleurochrysis carterae\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
degrees 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.

Growth Cycle (14 d) Culture Dynamics Monitoring:\u00a0 To understand the
chemical and biological culture dynamics over an entire growth cycle (14 days,
where days 1-9 represented exponential growth), the investigators took
measurements of one culture from each\u00a0pCO2\u00a0treatment every day at
approximately the same time of day for one full growth cycle.\u00a0 Our pH
electrode malfunctioned on days 7 and 8, and the total alkalinity sample from
the 750 ppm treatment on day 8 was accidentally dropped and broken, so
calculations of full carbonate chemistry parameters for days 7 and 8 were not

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 weekly 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

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\u00a0using the corresponding cell density measurements.

Particulate Organic Carbon:\u00a0\u00a0To determine the bulk culture POC
concentration, 10 mL of culture were filtered onto a pre-combusted Whatman
GF/F filter, which was then fumed in 10 % HCl to remove inorganic
carbonates.\u00a0 The dried filters were then analyzed on an ECS 4010 CHNSO
Analyzer (Costech Analytical Technologies, Valencia, CA, USA) by Bigelow
Analytical Services, East Boothbay, ME, USA.\u00a0 Bulk culture POC
measurements were corrected to POC/cell\u00a0using the corresponding cell
density measurements.

Nutrients:\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), nitrite, phosphate, and silicate were measured by
Continuous Flow Analysis by Bigelow Analytical Services using a SEAL
AutoAnalyzer 3 HR (SEAL Analytical Inc., Mequon, WI, USA). \u00a0

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).

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.
