attribute NC_GLOBAL acquisition_description String Dilution Experiments: For an overview of the purpose and interpretation of\ndilution experiments see Landry (1993) and Worden & Binder (2003). Seawater\nsamples were taken with Go-Flo bottles suspended on non-metallic cable. A\nportion of this water was gravity-filtered through 0.2 um pore-size capsule\nfilters (Whatman Polycap 36 TC), and appropriate volumes of filtered and\nunfiltered seawater were added to 500 ml polycarbonate bottles to achieve the\nindicated dilutions. Time-0 (T0) samples were removed from each bottle and\npreserved for later flow cytometric analysis as described below. Incubation\nbottles were then distributed to nylon mesh bags and resuspended in the water\ncolumn at the depths indicated. After 24 hours, the bottles were recovered and\nsampled for time-final (TF) counts. All sampling gear, filters, and incubation\nbottles were acid-washed per Fitzwater et al. (1982). The dates, times, and\nlocations of the experiments were as follows:\n \n\\u00a0\n \nCruise\\u00a0 \\u00a0 \\u00a0 Exper\\u00a0 \\u00a0 Date (UTC)\\u00a0 \\u00a0 T0\n(UTC)\\u00a0 \\u00a0 \\u00a0E Long\\u00a0 \\u00a0 \\u00a0N Lat\n \nCH0409\\u00a0 \\u00a0 X1\\u00a0 \\u00a0 \\u00a0 \\u00a0 \\u00a026-May-09\\u00a0 \\u00a0\n\\u00a017:58:30\\u00a0 \\u00a0 \\u00a0-71.998\\u00a0 \\u00a0 30.171\n \nCH0409\\u00a0 \\u00a0 X2\\u00a0 \\u00a0 \\u00a0 \\u00a0 \\u00a029-May-09\\u00a0 \\u00a0\n\\u00a013:28:09\\u00a0 \\u00a0 \\u00a0-72.002\\u00a0 \\u00a0 30.173\n \nCH0510\\u00a0 \\u00a0 X2\\u00a0 \\u00a0 \\u00a0 \\u00a0 \\u00a027-May-10\\u00a0 \\u00a0\n\\u00a013:33:30\\u00a0 \\u00a0 \\u00a0-72.683\\u00a0 \\u00a0 30.699\n \n\\u00a0\n \nFlow Cytometric Cell Counts: Samples were fixed with freshly titrated\nparaformaldehyde (pH 7.4\\u20138.1, 0.1% final concentration), held in the dark\nfor 10 min, frozen in liquid nitrogen, and stored in a \\u201180 deg C freezer\n(CH0409 samples) or in liquid nitrogen (CH0510 samples) until analysis.\nPreserved samples were analyzed by flow cytometry on a modified Coulter-EPICS\n753 flow cytometer (Binder et al. 1996). Samples were chosen in random order\nand defrosted in a 30 deg C water bath (just long enough to melt, ~5 min).\nPrior to analysis, polystyrene fluorescent beads (Flow Check\\u00ae 0.494 um\n\\u201cBB\\u201d; Polysicences Inc., Washington, PA, USA), were added to each\nsample, and used to normalize cellular light scatter and fluorescence. Samples\nwere typically run at an infusion rate of 20 uL min-1 for 1 to 20 min,\ndepending on cell abundance within the sample. A minimum of 1,000\nProchlorococcus cells were analyzed, except for samples in which low cell\nconcentrations made this impractical. Final cell concentrations tabulated here\nwere calculated from 1-7 replicate counts (Count.n).

attribute NC_GLOBAL instruments_1_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.\n(from: http://www.bio.umass.edu/micro/immunology/facs542/facswhat.htm)

attribute NC_GLOBAL project String Picophytoplankton_Regulation
attribute NC_GLOBAL projects_0_acronym String Picophytoplankton_Regulation
attribute NC_GLOBAL projects_0_description String The intellectual merit of the research is to extend our understanding of the biology and ecology of marine picophytoplankton, a group of microbes that are responsible for a large proportion of the total photosynthetic carbon fixation that occurs in the world's oceans. The importance of picophytoplankton as the dominant primary producers in open-ocean ecosystems is well-established. However, the factors that regulate the distribution and abundance of these populations remain poorly understood. The investigators will explore the dynamics of top-down (grazer-mediated) regulation of picophytoplankton populations in a specific context: the maintenance of summertime subsurface maxima in the pico-cyanobacterium Prochlorococcus (but not Synechococcus) in the Sargasso Sea. This phenomenon represents a relatively simple and predictable model system within which to test hypotheses about the regulation of oceanic picophytoplankton in general.\nRecent results suggest that despite their abundance, Prochlorococcus in the subsurface maxi-mum are growing (and being grazed) rather slowly, as compared to the smaller population at the surface. In order to understand the factors responsible for this apparent paradox, this project will use a combination of field and laboratory studies to characterize and compare the interactions between Prochorococcus and its protozoan grazers at these two contrasting depths, and in relation to Synechococcus, which forms no such sub-surface maximum.\nThe broader impacts include training for graduate and undergraduate students. In addition, given the significance of picophytoplankton as primary producers at the base of oceanic microbial food webs, the results of this project should inform efforts to describe and model the broader oceanic ecosystem, and ultimately to understand its role in the global carbon cycle.
