attribute NC_GLOBAL acquisition_description String Three CO2 concentrations were tested: 410 ppm, 750 ppm, and 1000 ppm
respectively. For each CO2 concentration, four temperatures were tested: 15
degrees-C, 20 degrees-C, 25 degrees-C, and 30 degrees-C. Within each
temperature, three light levels were tested: a sub-optimum light (SOL)
intensity of 60 umol photons \u00b7 m-2 \u00b7 s-1, an optimum light (OL)
intensity of 400 umol photons \u00b7 m-2 \u00b7 s-1 and an extreme light (EL)
intensity of 800 umol photons \u00b7 m-2 \u00b7 s-1. All lights were set at a
12 h day: 12 h dark cycle. For logistical reasons, experiments were partially
conducted in series, with all light treatments at two temperatures (either 15
degrees-C and 25 degrees-C or 20 degrees-C and 30 degrees-C) running
simultaneously. This was repeated for each CO2 concentration.

Experiments were conducted in Multicultivator MC-1000 OD units (Photon Systems
Instruments, Drasov, Czech Republic). Each unit consists of eight 85 ml test-
tubes immersed in a thermostated water bath, each independently illuminated by
an array of cool white LEDs set at specific intensity and timing. A 0.2um
filtered CO2-air mix (Praxair Distribution Inc.) was bubbled through sterile
artificial seawater, and the humidified gas mix was supplied to each tube via
gentle sparging through a 2um stainless steel diffuser. Flow rates were
gradually increased over the course of the incubation to compensate for the
DIC uptake of actively growing cells, and ranged from <0.04 Liters per minute
(LPM) at the start of the incubations to 0.08 LPM in each tube after 2 days.
For each CO2 and temperature level, replication was achieved by incubating
three tubes at sub-optimum light intensities, two tubes at optimum light
intensity, and three tubes at extreme light intensities. Each experiment was
split into two phases: An acclimation phase spanning 4 days, was used to
acclimate cultures to their new environment. Pre-acclimated, exponentially-
growing cultures were then inoculated into fresh media and incubated through a
3-day experimental phase during which assessments of growth, photophysiology,
and nutrient cycling were carried out daily. All sampling started 5 hours into
the daily light cycle to minimize the effects of diurnal cycles.

Experiments were conducted with artificial seawater (ASW) prepared using
previously described methods (Kester et. al 1967), and enriched with nitrate
(NO3), phosphate (PO4), silicic acid (Si[OH]4), at levels ensuring that the
cultures would remain nutrient-replete over the course of the experiment.
Trace metals and vitamins were added as in f/2 (Guillard 1975). The expected
DIC concentration and pH of the growth media was determined for the different
pCO2 and temperatures using the CO2SYS calculator (Pierrot et al. 2006), with
constants from Mehrbach et al. (1973, refit by Dickson & Millero 1987), and
inputs of temperature, salinity, total alkalinity (2376.5 umol \u00b7 kg-1),
pCO2, phosphate, and silicic acid. DIC levels in ASW at the start of each
phase of the experiments were manipulated by the addition of NaHCO3, and was
then maintained by bubbling a CO2-Air mix through the cultures over the course
of the experiments. The pH of the growth media was measured
spectrophometrically using the m-cresol purple method (Dickson 1993), and
adjusted using 0.1N HCl or 0.1M NaOH. The media was distributed into 75 ml
aliquots and each aliquot was inoculated with 5 ml of the T. pseudonana CCMP
1014 (TP1014) stock culture at the start of the experiments.

Flow cytometry:
Samples were fixed in Hexamethylenetetramine-buffered formaldehyde (final
concentration 1% v/v) and stored at 4 degrees C in the dark for a maximum of 4
days. Cell counts were confirmed to be unaffected over storage for up to a
week. Samples were analyzed on a Guava easyCyte HT Benchtop Flow Cytometer
(Millipore-Sigma, USA). All data acquisitions were done with logarithmic
signal amplification. Cytometer sample flow rates were kept low (0.24 uL
\u00b7 s-1) to accommodate high cell concentrations. Diatoms were identified
based on size and chlorophyll autofluorescence using the forward scatter
channel (FSC) and Red-FL (695/50 nm) channel respectively. Growth rates were
derived by fitting an exponential curve to cell concentrations vs. time for a
48-hour period during which cells exhibited exponential growth in the
experimental phase. Growth rates in treatments where cells did not grow, or
declined in abundance were listed as 0. Particle sizes (equivalent spherical
diameter in \u00b5m, ESD) were derived from FSC using size-calibration beads
of known diameters ranging from 2 \u00b5m to 10 um (Particle Size standard
kit, Spherotech Inc.).

attribute NC_GLOBAL instruments_0_description String Flow cytometers (FC or FCM) are automated instruments that quantitate properties of single cells, one cell at a time. They can measure cell size, cell granularity, the amounts of cell components such as total DNA, newly synthesized DNA, gene expression as the amount messenger RNA for a particular gene, amounts of specific surface receptors, amounts of intracellular proteins, or transient signalling events in living cells.

attribute NC_GLOBAL project String Stressors on Marine Phytoplankton
attribute NC_GLOBAL projects_0_acronym String Stressors on Marine Phytoplankton
attribute NC_GLOBAL projects_0_description String The overarching goal of this project is to develop a framework for understanding the response of phytoplankton to multiple environmental stresses. Marine phytoplankton, which are tiny algae, produce as much oxygen as terrestrial plants and provide food, directly or indirectly, to all marine animals. Their productivity is thus important both for global elemental cycles of oxygen and carbon, as well as for the productivity of the ocean. Globally the productivity of marine phytoplankton appears to be changing, but while we have some understanding of the response of phytoplankton to shifts in one environmental parameter at a time, like temperature, there is very little knowledge of their response to simultaneous changes in several parameters. Increased atmospheric carbon dioxide concentrations result in both ocean acidification and increased surface water temperatures. The latter in turn leads to greater ocean stratification and associated changes in light exposure and nutrient availability for the plankton. Recently it has become apparent that the response of phytoplankton to simultaneous changes in these growth parameters is not additive. For example, the effect of ocean acidification may be severe at one temperature-light combination and negligible at another. The researchers of this project will carry out experiments that will provide a theoretical understanding of the relevant interactions so that the impact of climate change on marine phytoplankton can be predicted in an informed way. This project will engage high schools students through training of a teacher and the development of a teaching unit. Undergraduate and graduate students will work directly on the research. A cartoon journalist will create a cartoon story on the research results to translate the findings to a broader general public audience.
Each phytoplankton species has the capability to acclimatize to changes in temperature, light, pCO2, and nutrient availability - at least within a finite range. However, the response of phytoplankton to multiple simultaneous stressors is frequently complex, because the effects on physiological responses are interactive. To date, no datasets exist for even a single species that could fully test the assumptions and implications of existing models of phytoplankton acclimation to multiple environmental stressors. The investigators will combine modeling analysis with laboratory experiments to investigate the combined influences of changes in pCO2, temperature, light, and nitrate availability on phytoplankton growth using cultures of open ocean and coastal diatom strains (Thalassiosira pseudonana) and an open ocean cyanobacteria species (Synechococcus sp.). The planned experiments represent ideal case studies of the complex and interactive effects of environmental conditions on organisms, and results will provide the basis for predictive modeling of the response of phytoplankton taxa to multiple environmental stresses.
