attribute NC_GLOBAL acquisition_description String Surficial sediments were collected using a multi-corer.\n \nFive substrates linked to a 7-amido-4-methyl coumarin (MCA) fluorophore, one\namino acid \\u2013 leucine \\u2013 and four oligopeptides \\u2013 the\nchymotrypsin substrates alanine-alanine-phenylalanine (AAF) and alanine-\nalanine-proline-phenylalanine (AAPF), and the trypsin substrates glutamine-\nalanine-arginine (QAR) and glutamic acid-gylcine-arginine (EGR) \\u2013 were\nused to measure exo- and endo-acting peptidase activities, respectively.\nHydrolysis rates of the substrates were measured as an increase in\nfluorescence as the fluorophore was hydrolyzed from the substrate over time\n[as in Hoppe, 1993; Obayashi and Suzuki, 2005]. For sediment measurements,\npeptidase activities were measured in a 1:2 (vol: vol) sediment: autoclaved\nseawater slurry. 100 micromolar concentrations of substrate were added to\ntriplicate live and single autoclaved killed control incubations. 2 ml of\nslurry was centrifuged at each timepoint (0, 1h ,2h, and 4 h), filtered, and\ndiluted with 1 ml borate buffer; fluorescence was measured in a 4 ml\ncuvette.\\u00a0 Hydrolysis rates were calculated from the rate of increase of\nfluorescence in the incubation over time relative to a set of standards of\nknown concentration of fluorophore.\n \nAll incubations were conducted at 0 C in the dark.

attribute NC_GLOBAL instruments_0_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 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.
