attribute NC_GLOBAL acquisition_description String Three CO2 concentrations were tested: 410 ppm, 750 ppm, and 1000 ppm\nrespectively. For each CO2 concentration, four temperatures were tested: 15\ndegrees-C, 20 degrees-C, 25 degrees-C, and 30 degrees-C. Within each\ntemperature, three light levels were tested: a sub-optimum light (SOL)\nintensity of 60 umol photons \\u00b7 m-2 \\u00b7 s-1, an optimum light (OL)\nintensity of 400 umol photons \\u00b7 m-2 \\u00b7 s-1 and an extreme light (EL)\nintensity of 800 umol photons \\u00b7 m-2 \\u00b7 s-1. All lights were set at a\n12 h day: 12 h dark cycle. For logistical reasons, experiments were partially\nconducted in series, with all light treatments at two temperatures (either 15\ndegrees-C and 25 degrees-C or 20 degrees-C and 30 degrees-C) running\nsimultaneously. This was repeated for each CO2 concentration.\n \nExperiments were conducted in Multicultivator MC-1000 OD units (Photon Systems\nInstruments, Drasov, Czech Republic). Each unit consists of eight 85 ml test-\ntubes immersed in a thermostated water bath, each independently illuminated by\nan array of cool white LEDs set at specific intensity and timing. A 0.2um\nfiltered CO2-air mix (Praxair Distribution Inc.) was bubbled through sterile\nartificial seawater, and the humidified gas mix was supplied to each tube via\ngentle sparging through a 2um stainless steel diffuser. Flow rates were\ngradually increased over the course of the incubation to compensate for the\nDIC uptake of actively growing cells, and ranged from <0.04 Liters per minute\n(LPM) at the start of the incubations to 0.08 LPM in each tube after 2 days.\nFor each CO2 and temperature level, replication was achieved by incubating\nthree tubes at sub-optimum light intensities, two tubes at optimum light\nintensity, and three tubes at extreme light intensities. Each experiment was\nsplit into two phases: An acclimation phase spanning 4 days, was used to\nacclimate cultures to their new environment. Pre-acclimated, exponentially-\ngrowing cultures were then inoculated into fresh media and incubated through a\n3-day experimental phase during which assessments of growth, photophysiology,\nand nutrient cycling were carried out daily. All sampling started 5 hours into\nthe daily light cycle to minimize the effects of diurnal cycles.\n \nExperiments were conducted with artificial seawater (ASW) prepared using\npreviously described methods (Kester et. al 1967), and enriched with nitrate\n(NO3), phosphate (PO4), silicic acid (Si[OH]4), at levels ensuring that the\ncultures would remain nutrient-replete over the course of the experiment.\nTrace metals and vitamins were added as in f/2 (Guillard 1975). The expected\nDIC concentration and pH of the growth media was determined for the different\npCO2 and temperatures using the CO2SYS calculator (Pierrot et al. 2006), with\nconstants from Mehrbach et al. (1973, refit by Dickson & Millero 1987), and\ninputs of temperature, salinity, total alkalinity (2376.5 umol \\u00b7 kg-1),\npCO2, phosphate, and silicic acid. DIC levels in ASW at the start of each\nphase of the experiments were manipulated by the addition of NaHCO3, and was\nthen maintained by bubbling a CO2-Air mix through the cultures over the course\nof the experiments. The pH of the growth media was measured\nspectrophometrically using the m-cresol purple method (Dickson 1993), and\nadjusted using 0.1N HCl or 0.1M NaOH. The media was distributed into 75 ml\naliquots and each aliquot was inoculated with 5 ml of the T. pseudonana CCMP\n1014 (TP1014) stock culture at the start of the experiments.\n \nPhotophysiology:  \n Photophysiology was assessed daily using a handheld Pulse Amplitude\nModulated (PAM) fluorometer (AquaPen-C AP-C 100, Photon System Instruments,\nCzech Republic). A sample was collected from each light treatment for each, 5\nhours after the start of the daily light cycle, and placed in the dark for a\nminimum of 30 minutes prior to measurements. The dark-adapted sample was used\nto generate light curves that provide measurements of in-vivo chlorophyll\nautofluorescence (F0), the maximum quantum yield (QYmax or Fv/Fm), and\nrelative photosynthesis rates based on PSII quantum yields at varying light\nintensities - using the instrument\\u2019s LC3 protocol. The LC3 protocol\ninvolves measurements of baseline and maximal fluorescence over seven\n60-second phases, with each phase representing a light intensity from 10 to\n1000 \\u03bcmol photons m-2 \\u00b7 s-1.\\u00a0 Blue light (455 nm) was used as\nactinic light in these experiments, and measurements were made at measuring\nillumination (f-pulse) intensity of 0.03 \\u03bcmol photons m-2 \\u00b7 s-1, and\nsaturating (F-pulse) illumination of 2100\\u2009micro-mol photons m-2 \\u00b7\ns-1, and actinic illumination (A-pulse) controlled by the instrument's\nprotocol were set at 10, 20, 50, 100, 300, 500, and 1000 micro-mol photons m-2\n\\u00b7 s-1 (for each 60-second phase).

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.\nEach 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.
