attribute NC_GLOBAL acquisition_description String Methodology:\\u00a0from\\u00a0Parsons et al (2011):\n \nStudy site and sample collection:  \n Samples were collected aboard the\\u00a0RV Weatherbird II\\u00a0or the\\u00a0RV\nAtlantic Explorer\\u00a0at the BATS site (31\\u00b0 40\\u2032 N, 64\\u00b010\\u2032\nW). All cruises were conducted as part of the larger BATS program and sampled\nat least monthly with biweekly sampling between February and April. This\nsampling strategy has been successful in revealing the major temporal\nmicrobial and biogeochemical patterns at this site (Carlson and Ducklow,\n1996;\\u00a0Steinberg et al., 2001;\\u00a0Morris et al., 2005;\\u00a0Carlson et\nal., 2009;\\u00a0Treusch et al., 2009;\\u00a0Lomas et al., 2010). A broader\nassessment of the BATS biogeochemical data is presented in\\u00a0Deep Sea\nResearch II\\u00a0in 1996 (volume 43, issues 2\\u20133) and 2001 (volume 48,\nissues 8\\u20139).\n \nSamples for virioplankton (0, 20, 40, 60, 80, 100, 140, 160, 200, 250 and\n300\\u2009m) and bacterioplankton (0, 10, 20, 40, 60, 80, 100, 120, 140, 160,\n200, 250 and 300\\u2009m) were collected at the BATS site from January 2000 to\nDecember 2009 via conductivity, temperature, depth profiling rosette equipped\nwith 12\\u2009l Niskin bottles. The 120\\u2009m virioplankton sample was added\nafter October 2007. Throughout the entire time-series, all virioplankton\nsamples were fixed with 0.02\\u2009um filtered formalin (1% final\nconcentration), placed in 5\\u2009ml cryovials and flash frozen in liquid\nnitrogen (Wen et al., 2004) until processing (within 12 weeks of collection).\nSamples for bacterioplankton abundance were fixed with 0.2\\u2009um filtered\ngluteraldehyde (1% final concentration) and stored at either 4\\u2009\\u00b0C\nfor 72\\u2009h or flash frozen and subsequently stored at \\u221280\\u2009\\u00b0C\nfor up to 6 months until processing as described in\\u00a0Steinberg et al\n(2001). Storage tests demonstrated no appreciable loss of virioplankton or\nbacterioplankton abundance when stored in liquid nitrogen for periods up to 6\nmonths (unpublished data). Picophytoplankton samples were collected at the\nsame depths through 250\\u2009m from October 2001 to December 2009 (Casey et\nal., 2007). Samples for fluorescence\\u00a0in situ\\u00a0hybridization (FISH) of\nspecific heterotrophic bacterioplankton lineages were collected from the upper\n300\\u2009m from January 2003 to December 2005 (Carlson et al., 2009).\n \nBiogeochemical and physical data collected at the BATS site are available\nat\\u00a0[http://bats.bios.edu](\\\\\"http://bats.bios.edu\\\\\"). The MLD was\ndetermined as the depth where potential density (sigma-t) of the water was\nequal to sea surface sigma-t\\u00a0plus the equivalent in sigma-t\\u00a0to a\n0.2\\u2009\\u00b0C decrease in temperature (Sprintall and Tomczak, 1992).\nContour plots were created in Ocean Data View (R\nSchlitzer,\\u00a0[https://odv.awi.de/](\\\\\"https://odv.awi.de/\\\\\")) with VG\nGridding and linear mapping adjusted to the median of each data set.\nStatistics (Pearson's correlation and two-tailed Student's\\u00a0t-test for\nunequal variances), ratios and percent contributions were determined using\nMicrosoft Excel.\n \nVirioplankton abundance:  \n Virioplankton abundance was enumerated according to the methods\nof\\u00a0Noble and Fuhrman (1998). Briefly, water samples were filtered on to\n0.02\\u2009um Anodisc aluminum oxide filters (Whatman, Kent, UK), stained with\nSYBR Green I (Molecular Probes Inc., Eugene, OR, USA), and enumerated via\nepifluorescence microscopy using an Olympus AX70 microscope (Olympus, Tokyo,\nJapan) equipped with a Toshiba CCD video camera (Irvine, CA, USA) and Pro-\nseries Capture Kit version 4.5 (I-CUBE, Crofton, MD, USA). Ten images from\neach sample were processed with scripts written in Image Pro Plus (Media\nCybernetics, Bethesda, MD, USA) for particles sized 0.01\\u20130.27\\u2009um2,\nusing the clean borders function (cells touching the edge of the image or grid\nwere omitted). We consider these estimates of viral abundance conservative\nbecause it is possible that some viral particles less than one pixel were\nomitted from the final count. We performed pairwise comparisons of automated\nversus manual enumeration of virioplankton abundance to determine any\ndiscrepancies between the two approaches. Samples collected along a gradient\nfrom offshore (BATS;\\u00a0n=92) to onshore waters of Bermuda (n=32) were\nhighly correlated with automated counts being slightly greater than manual\ncounts (slope=1.07,\\u00a0r=0.99,\\u00a0n=134). The lower estimates of viral\nabundance from manual counts may have resulted from image fading during\nenumeration and/or operator fatigue. We argue that for this study, the\nautomated image analysis was the most reliable approach for viral particle\nenumeration. The coefficient of variation for the automated counts averaged\n11% (n=1517).

attribute NC_GLOBAL instruments_0_description String A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

attribute NC_GLOBAL instruments_1_description String The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column.  The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or  radiometers.  It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.  This instrument designation is used when specific make and model are not known.

attribute NC_GLOBAL projects_0_description String (Adapted from the NSF award abstract)\nThe premise of this project is that stratified bacterioplankton clades engage in specialized biogeochemical activities that can be identified by integrated oceanographic and microbiological approaches. Specifically, the objective of this project is to assess if the mesopelagic microbial community rely on diagenetically altered organic matter and subcellular fragments that are produced by microbial processes in the euphotic zone and delivered into the upper mesopelagic by sinking or mixing. In past efforts this microbial observatory had greater success cultivating members of the euphotic zone microbial community, and revealed an unanticipated growth requirement for reduced sulfur compounds in alphaproteobacteria of the SAR11 clade. Genomic information showed that intense competition for substrates imposes trade-offs on bacterioplankton - there are regions of N dimensional nutrient space where specialists win. We postulate that specific growth requirements may explain some the regular spatial and temporal patterns that have been observed in upper mesopelagic bacterioplankton communities, and the difficulties of culturing some of these organisms.\nThe specific objectives of this project are: 1) to produce 13C and 15N labeled subcellular (e.g., soluble, cell wall, and membrane) and DOM fractions from photosynthetic plankton cultures and use stable isotope probing to identify specific clades in the surface and upper mesopelagic microbial community that assimilate fractions of varying composition and lability. 2) to use fluorescence in situ hybridization approaches to monitor temporal and spatial variability of specific microbial populations identified from the SIP and HTC experiments. To increase resolution we will use CARD-FISH protocols. 3) to measure the proteomes of bacterioplankton communities to identify highly translated genes in the surface layer and upper mesopelagic, and community responses to seasonal nutrient limitation. 4) and, to cultivate these organisms via high throughput culturing (HTC) by pursuing the hypothesis that they require specific nutrient factors and/or diagenetically altered organic substrates. Complete genome sequences from key organisms will be sought and used as queries to study patterns of natural variation in genes and populations that have been associated with biogeochemically important functions.
