attribute NC_GLOBAL acquisition_description String Study Site and CTD Casts  \n Data were collected on four cruises in the Sargasso Sea on board the R/V\nAtlantic Explorer. On each cruise, sampling was conducted at three stations:\nthe center and edge of a mesoscale eddy and at one station outside of the\neddy. Eddies were identified using satellite-derived sea level anomaly (SLA)\ndata provided by Dr. Dennis McGillicuddy and Dr. Valery Kosnyrev of the Woods\nHole Oceanographic Institution. Target eddies (one per cruise) were initially\nidentified on the day of departure; the ship's position within the eddy (at\nthe center or the edge, as appropriate) was confirmed by daily checks of SLA\ndata.\n \nAt each station, high resolution CTD casts to ~2000 m were performed at noon\nto measure core physical, chemical and biological parameters of the water\ncolumn. In addition to the core CTD casts, pre-dawn \\\"Productivity\\\" CTD casts\nwere performed to collect water for measurements of size-fractionated biomass\n(as chl a) and size-fractionated primary productivity. Samples were obtained\nusing the 24 bottle Niskin rosette from 3-4 depths (20 m, 40-50 m, deep\nfluorescence maximum (~80 m), and 100 m). Ten-liter polycarbonate collection\nbottles (covered with black tape) were pre-rinsed with sample water and were\nfilled by draining the Niskin bottles through opaque tubing. All samples were\npre-filtered through a 200 um Nitex screen. Further handling of the samples\nwas done in the dark or under red light.\n \nThe 200 um pre-screened water from pre-dawn productivity casts was used for\nmeasurements of size-fractionated biomass (as chl a) and biomarker\nphotopigments by HPLC and for measurements of size-fractionated primary\nproductivity.\\u00a0 HPLC pigments were also used for taxonomic identification\nof total and size-fractionated phytoplankton groups using ChemTax analyses.\nSamples for microscopy were also taken from productivity casts as verification\nof the ChemTax results using methods described above for core CTD casts.\\u00a0\n \nTotal phytoplankton biomass was measured directly by filtering triplicate\naliquots of 1 to 2 liters of pre-screened water onto GF/F filters. This gave\ntotal chl a in the size fraction 0.7 to 200 um. The biomass of three size\nclasses of phytoplankton was quantified by differential filtration: the\npicophytoplankton (0.7-2 um), the nanophytoplankton (2-20 um) and the\nmicrophytoplankton (20-200 um) as follows. Triplicate aliquots of 1 to 2\nliters of pre-screened water were filtered through a 2 um Nuclepore filter\nthen onto a GF/F filter (= picophytoplankton, 0.7-2 um). Triplicate aliquots\nof pre-screened water were also filtered through a 20 um Nitex mesh then onto\na GF/F filter (= 0.7-20 um). Biomass of the nanophytoplankton size class was\ndetermined by subtracting the picophytoplankton biomass from the 0.7-20 um\nbiomass. Microphytoplankton biomass was determined by subtracting the 0.7-20\num biomass from the total chl a value. Filters were folded and placed in 1.5\nml cryotubes and frozen at -80\\u00b0 C until later analysis at the University\nof South Carolina (USC) using the methods below.\\u00a0\n \nPrimary Prodcutivity Measurements  \n For size-fractionated primary productivity measurements, 200 um pre-screened\nwater collected from discrete depths were dispensed into Nalgene polycarbonate\nincubation bottles (7-8 clear bottles plus 1-2 dark bottles per depth;\n800-1200 ml each). Bottles were spiked with 14C-labeled sodium bicarbonate\n(PerkinElmer Health Sciences Inc.) to a final activity 0.04-0.08 uCi ml-1 per\nbottle. An additional bottle per depth was used as a particulate blank (T0)\n(Barber et al., 1996). The T0 bottles were immediately filtered onto a GF/F,\nacidified with 500 ul 0.5 N HCl and left open to fume for 24 hours (Barber et\nal., 1996). Samples for total counts (Tc; 100 ul) were collected from one\nbottle per depth and combined with 200 ul of phenylethylamine (PEA) and 5 ml\nof scintillation cocktail (EcoLume, MPBiomedicals, Solon, Ohio). All bottles\nwere incubated in situ at the depth of collection. Incubations were started\nbefore sunrise (usually between 05:00 and 06:00 h) and were terminated 24 h\nlater. The productivity array was tracked using a Telonics, Inc. transponder\nplatform subscribed to the ARGOS satellite tracking system.\n \nTotal phytoplankton primary productivity was measured directly by filtering\ntriplicate incubation bottles onto GF/F filters. This gave total primary\nproductivity in the size fraction 0.7 to 200 um. Dark bottle productivity was\nalso measured directly by filtering dark bottles directly onto GF/F filters (=\ndark productivity; 0.7-200 um). Size-fractionated rates of primary\nproductivity of the picophytoplankton, nanophytoplankton and\nmicrophytoplankton were made by differential filtration. Two 1 liter bottles\nwere filtered through a 20 um Nitex mesh then onto a 2 um Nuclepore filter (=\nnanophytoplankton, 2-20 um). Two or three 1 liter bottles were filtered\nthrough a 20 um Nitex mesh then onto a GF/F filter (= 0.7-20 um).\\u00a0\nFilters were treated with 500 ul of 0.5 N HCl and left under a fumehood for 24\nhours, then combined with 10 ml scintillation cocktail.\\u00a0 Radioactivity\nwas determined in disintegrations per minute (DPM) by the shipboard liquid\nscintillation analyzer (Packard Tri-Carb 2000CA).\\u00a0\n \nRates of primary productivity (PP) were calculated in units of mg C m-3 d-1\nusing the methods of Barber et al. (1996) with the addition of dark bottles:\n \n\\u00a0\\u00a0\\u00a0 PP = (DPM24 \\u2013 DPM0 \\u2013 DPMd)/(1.05)(25200 mg C\nm-2)(DPMtot * time)-1\\u00a0\\u00a0\\u00a0 \\u00a0\\u00a0\\u00a0\n \nwhere DPM24 = activity on filter after 24 hour incubation; DPM0 = activity of\n(depth-specific) T0 particulate blank; DPMd = average of (depth-specific) dark\nbottles; DPMtot = total activity DPM of isotope added multiplied by volume of\nwater filtered (DPM ml-1); 1.05 = constant that accounts for preferential\nuptake of the lighter isotope 12C over 14C; 25,200 = concentration (in mg m-2)\nof inorganic carbon in seawater.\n \nThe rate of primary productivity for the picophytoplankton size class was\ndetermined by subtracting the nanophytoplankton productivity from the 0.7-20\num productivity. Primary productivity for the microphytoplankton size class\nwas determined by subtracting the 0.7-20 um productivity from the total\nprimary productivity, 0.7-200 um. Total and size-fractionated rates of primary\nproductivity were integrated to 100 meters using trapezoidal integration (mg C\nm-2 d-1).\n \nMicroscopy  \n Samples preserved in Lugol\\u2019s were settled overnight in a 100 ml\nsedimentation chamber and enumerated at 400x using a Nikon TS-100 Eclipse\ninverted microscope. A minimum of 400 cells per sample were counted to give a\nconfidence interval of \\u00b110 % (Guillard, 1973). Phytoplankton taxa were\nidentified to the lowest taxonomic level possible, that is, in most cases, to\ngenus.\n \nHPLC and ChemTax  \n Samples for HPLC analysis were lyophilized for 24 h at -50\\u00b0 C, placed\nin 90% acetone (0.45-0.55 ml), and extracted at -20\\u00b0 C for 24 h.\\u00a0\nFiltered extracts (350 \\u00b5l) were injected into a Shimadzu HPLC equipped\nwith a monomeric (Rainin Microsorb-MV, 0.46 x 10 cm, 3 \\u00b5m) and a\npolymeric (Vydac 201TP54, 0.46 x 25 cm, 5 um) reverse-phase C18 column in\nseries. A nonlinear binary gradient consisting of the solvents 80% methanol:\n20% 0.50 M ammonium acetate and 80% methanol: 20% acetone was used for pigment\nseparations (Pinckney et al. 1996). Absorption spectra and chromatograms (440\n\\u00b1 4 nm) were acquired using a Shimadzu SPD-M10av photodiode array\ndetector. Pigment peaks were identified by comparison of retention times and\nabsorption spectra with pure standards (DHI, Denmark). The synthetic\ncarotenoid \\u00df-apo-8'-carotenal (Sigma) was used as an internal standard.\nContributions of individual algal groups to total community composition and to\neach size class was determined by chemical taxonomy using the ChemTax matrix\n(Mackey et al., 1996).

attribute NC_GLOBAL instruments_1_description String The Sea-Bird SBE 9 is a type of CTD instrument package.  The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911.  The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used.  more information from Sea-Bird Electronics

attribute NC_GLOBAL instruments_2_description String A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

attribute NC_GLOBAL instruments_3_dataset_instrument_nid String 6222
attribute NC_GLOBAL instruments_3_description String An inverted microscope is a microscope with its light source and condenser on the top, above the stage pointing down, while the objectives and turret are below the stage pointing up. It was invented in 1850 by J. Lawrence Smith, a faculty member of Tulane University (then named the Medical College of Louisiana).\n\nInverted microscopes are useful for observing living cells or organisms at the bottom of a large container (e.g. a tissue culture flask) under more natural conditions than on a glass slide, as is the case with a conventional microscope. Inverted microscopes are also used in micromanipulation applications where space above the specimen is required for manipulator mechanisms and the microtools they hold, and in metallurgical applications where polished samples can be placed on top of the stage and viewed from underneath using reflecting objectives.\n\nThe stage on an inverted microscope is usually fixed, and focus is adjusted by moving the objective lens along a vertical axis to bring it closer to or further from the specimen. The focus mechanism typically has a dual concentric knob for coarse and fine adjustment. Depending on the size of the microscope, four to six objective lenses of different magnifications may be fitted to a rotating turret known as a nosepiece. These microscopes may also be fitted with accessories for fitting still and video cameras, fluorescence illumination, confocal scanning and many other applications.

attribute NC_GLOBAL projects_0_description String Fluxes of particulate carbon from the surface ocean are greatly influenced by the size, taxonomic composition and trophic interactions of the resident planktonic community. Large and/or heavily-ballasted phytoplankton such as diatoms and coccolithophores are key contributors to carbon export due to their high sinking rates and direct routes of export through large zooplankton. The potential contributions of small, unballasted phytoplankton, through aggregation and/or trophic re-packaging, have been recognized more recently. This recognition comes as direct observations in the field show unexpected trends. In the Sargasso Sea, for example, shallow carbon export has increased in the last decade but the corresponding shift in phytoplankton community composition during this time has not been towards larger cells like diatoms. Instead, the abundance of the picoplanktonic cyanobacterium, Synechococccus, has increased significantly. The trophic pathways that link the increased abundance of Synechococcus to carbon export have not been characterized. These observations helped to frame the overarching research question, \"How do plankton size, community composition and trophic interactions modify carbon export from the euphotic zone\". Since small phytoplankton are responsible for the majority of primary production in oligotrophic subtropical gyres, the trophic interactions that include them must be characterized in order to achieve a mechanistic understanding of the function of the biological pump in the oligotrophic regions of the ocean.\nThis requires a complete characterization of the major organisms and their rates of production and consumption. Accordingly, the research objectives are: 1) to characterize (qualitatively and quantitatively) trophic interactions between major plankton groups in the euphotic zone and rates of, and contributors to, carbon export and 2) to develop a constrained food web model, based on these data, that will allow us to better understand current and predict near-future patterns in export production in the Sargasso Sea.\nThe investigators will use a combination of field-based process studies and food web modeling to quantify rates of carbon exchange between key components of the ecosystem at the Bermuda Atlantic Time-series Study (BATS) site. Measurements will include a novel DNA-based approach to characterizing and quantifying planktonic contributors to carbon export. The well-documented seasonal variability at BATS and the occurrence of mesoscale eddies will be used as a natural laboratory in which to study ecosystems of different structure. This study is unique in that it aims to characterize multiple food web interactions and carbon export simultaneously and over similar time and space scales. A key strength of the proposed research is also the tight connection and feedback between the data collection and modeling components.\nCharacterizing the complex interactions between the biological community and export production is critical for predicting changes in phytoplankton species dominance, trophic relationships and export production that might occur under scenarios of climate-related changes in ocean circulation and mixing. The results from this research may also contribute to understanding of the biological mechanisms that drive current regional to basin scale variability in carbon export in oligotrophic gyres.
