attribute NC_GLOBAL acquisition_description String For mesocosm (large volume) incubation experiments (referred to as\n\\u201cLV\\u201d incubations), a 30L Niskin bottle rosette was used to collect\nthe water. From each depth, 20L seawater from single Niskin bottles was\ndispensed using cleaned silicon tubing into a single carboy. Prior to filling,\ncarboys were rinsed 3x with water from the same Niskin bottle used to fill the\ncarboy. Six carboys were filled at each depth. Triplicate 20L carboys were\namended with ca. 500 mg (exact mass was recorded for each addition) of HMW\nThalassiosira; unamended triplicate carboys were used for controls. All\nmesocosms were incubated in the dark at near in-situ temperatures. Mesocosms\nwere sub-sampled at the start of incubation, and then after 2.5 d, 8d, 15d,\n28d, and 69d for the following assays: bacterial production using 3H-Leucine,\ndissolved organic carbon (DOC), nutrients, bacterial cell counts, peptidase,\nand glucosidase activity measurements. At the 15d timepoint, sub-samples were\nalso taken to measure polysaccharide hydrolase activities.\n \nSamples were analyzed for nutrients and DOC content modified after Grasshoff\nand Kremling [1999]. Clean and acid washed syringes, tubing, and filter\nholders were used for each sampling. Duplicate DOC samples were filtered using\nthe same 60 cc syringe through combusted glass fiber filters (Whatman\n1825-025) secured within a polycarbonate filter holder into two combusted 20\nmL scintillation vials and acidified using 100 \\u03bcL of 50% phosphoric acid\nthen immediately frozen at -20\\u00b0C.\\u00a0 DOC samples were analyzed by\nhigh-temperature catalytic oxidation (HTCO) using a Shimadzu Total Organic\nCarbon analyzer (TOC-8000A/5050A).\n \nBacterial protein production was measured from 3H-leucine incorporation by\nheterotrophic bacteria using the cold trichloroacetic acid (TCA) and\nmicrocentrifuge extraction method [as in Kirchman, 2001]. All work was\nperformed aboard ship. In brief, triplicate live samples of 1.5 mL seawater as\nwell as one 100% (w/v) TCA-killed control were incubated with 23 \\u03bcL of\nL-[3,4,5-3H(N)]-Leucine (PerkinElmer, NET460250UC) for between 4 and 24 hours\nin the dark at as close to in situ temperature as possible. Live samples were\nthen killed with 89 \\u03bcL of 100% (w/v) TCA and centrifuged (10,000 rpm at\n4\\u00b0C for 10 min) to pelletize cell material.\\u00a0 The supernatant liquid\nwas removed and 1 mL of 5% (w/v) TCA solution was added, followed by vortex\nmixing and centrifugation. Supernatant removal, mixing, and centrifugation\nwere repeated using 1 mL of 80% ethanol solution.\\u00a0 Finally, the\nsupernatant liquid was removed and each sample was dried overnight.\\u00a0\nAfter drying, 1 mL of scintillation cocktail (ScintiSafe 30% Cocktail, Fisher\nSX23-5) was added and incorporated radioactivity was measured using an LSA\nscintillation counter (PerkinElmer Tri-Carb 2910TR). Leucine incorporation\nrate was calculated from the incorporated radioactivity, compared to 1 mL of\nscintillation cocktail spiked with 23 \\u03bcL of L-[3,4,5-3H(N)]-Leucine\nradioactivity, divided by incubation time.

attribute NC_GLOBAL instruments_1_description String Liquid scintillation counting is an analytical technique which is defined by the incorporation of the radiolabeled analyte into uniform distribution with a liquid chemical medium capable of converting the kinetic energy of nuclear emissions into light energy. Although the liquid scintillation counter is a sophisticated laboratory counting system used the quantify the activity of particulate emitting (ß and a) radioactive samples, it can also detect the auger electrons emitted from 51Cr and 125I samples.

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nHeterotrophic microbial communities are key players in the marine carbon cycle, transforming and respiring organic carbon, regenerating nutrients, and acting as the final filter in sediments through which organic matter passes before long-term burial. Microbially-driven carbon cycling in the ocean profoundly affects the global carbon cycle, but key factors determining rates and locations of organic matter remineralization are unclear. In this study, researchers from the University of North Carolina at Chapel Hill will investigate the ability of pelagic microbial communities to initiate the remineralization of polysaccharides and proteins, which together constitute a major pool of organic matter in the ocean. Results from this study will be predictive on a large scale regarding the nature of the microbial response to organic matter input, and will provide a mechanistic framework for interpreting organic matter reactivity in the ocean.\nBroader Impacts: This study will provide scientific training for undergraduate and graduate students from underrepresented groups. The project will also involve German colleagues, thus strengthening international scientific collaboration.
