attribute NC_GLOBAL acquisition_description String Sediment and pore water collection:\n \nShort sediment cores were collected using a Bowers & Connelly megacorer, a\nmultiple coring device that can collect ~20-40 cm long sediment cores with\nundisturbed sediment surfaces. At two sites (stations 41 and 64) longer cores\n(up to ~2 m) were also collected with a Kasten corer.\n \nMegacorer cores were either sectioned for solid phase analysis, profiled with\npolarographic microelectrodes to determine dissolved O2 concentrations, or\nsectioned in a cold van under N2 for pore water sample extraction (for details\nsee, Komada et al., 2016). Kasten cores were brought into a large cold room\non-board ship, laid on their side and one side of the core box removed to\nexpose the sediment in the core. A plastic block was placed against the top of\nthe core to prevent slumping of the sediment during processing, and pore\nwaters were collected from these cores using Rhizon samplers (Seeberg-\nElverfeldt et al., 2005) inserted directly into the cores at measured\nintervals.\n \nPore water samples collected from both types of cores were filtered through\n0.45 \\u00b5m polycarbonate filters and processed as follows. Samples for\nalkalinity determinations were stored without a headspace in 3-ml plastic\nsyringes sealed with 3-way stopcocks. Titrated alkalinity samples (acidified\nto pH ~4 after titration) were stored in plastic snap cap vials, refrigerated\nand returned to ODU for the analysis of dissolved sulfate. Pore water samples\ncollected for the analysis of total dissolved Fe and Mn were acidified to pH\n<2 on-board ship with trace metal grade HCl, and store refrigerated until\nanalyzed back at ODU. Samples for pore water silicate analyses were analyzed\non board the research vessel. Additional samples for the analysis of other\ndissolved nutrients (nitrate, nitrite, ammonium, phosphate) were filtered into\ntightly capped sample vials and frozen for return to NEOL for analysis.\nSelected pore water samples (collected as described above) were also used for\nthe determination of dissolved organic carbon (DOC). These samples were\nfiltered directly into acid-cleaned and muffled (550 \\u00b0C for at least 4 h)\nglass ampules and were then acidified to pH < 2 with 6 N trace metal grade HCl\nand flame-sealed under a stream of UHP N2 gas. The sealed ampules were stored\nrefrigerated and returned to ODU for analysis.\n \nWhile it is possible to recover cores with intact sediment-water interfaces\nusing a megacorer, loss of surface sediments is typical during Kasten coring,\nmaking it not possible to directly determine absolute depths below the\nsediment-water interface in a Kasten core. We therefore determined the\nabsolute depths of pore water and solid phase sample intervals from Kasten\ncores by aligning Kasten core profiles of pore water alkalinity to megacore\nalkalinity profiles from the same site (Berelson et al., 2005; Komada et al.,\n2016).\n \nBottom water collection:\n \nBottom waters were collected by GO-Flo Bottles ~5-10 m off the seafloor. They\nwere filtered through 0.45 \\u00b5m polycarbonate filters and processed as\ndescribed above for pore water samples.\n \nPore water analyses: Sampled collected for alkalinity determination were\ntitrated aboard ship within 12 hours of collection by automated Gran titration\n(Hu and Burdige, 2008). Dissolved sulfate was determined on titrated\nalkalinity samples returned to ODU by ion chromatography and conductivity\ndetection (Thermo-Scientific Dionex ICS-5000; Burdige and Komada, 2011; Komada\net al., 2016). Concentrations of DOC were determined at ODU by high\ntemperature combustion using a Shimadzu TOC-V total carbon analyzer (Komada et\nal., 2013; Komada et al., 2016). Frozen samples for the determination of\ndissolved nutrients were returned to NEOL and analyzed by autoanalyzer for\nnitrate and nitrite (Armstrong et al., 1967; Pavlou, 1972), ammonium\n(Koroleff, 1970; Slawyk and MacIsaac, 1972) and dissolved inorganic phosphate\n(Drummond and Maher, 1995). Pore water silicate was determined on board the\nresearch vessel used fresh pore water samples and a manual colorimetric method\nfollowing Armstrong et al. (1967).\n \nPore water dissolved iron was determined colorimetrically at ODU using the\nferrozine technique (Stookey, 1970; Viollier et al., 2000). Hydroxylamine-HCl\n(0.2% final concentration) was added to the samples before analysis, to reduce\nany dissolved Fe3+ in the samples to Fe2+. The pore water iron results\nreported here therefore represent total dissolved iron (i.e., Fe2+ plus any\nFe3+ in the samples). This was done largely as a precaution against any iron\noxidation that may have occurred during sample storage, since it is assumed\nthat virtually all of the dissolved iron in these pore waters exists in situ\nas Fe2+ (e.g., Viollier et al., 2000).\n \nSamples for the analysis of dissolved manganese were determined with a\nmodification of the colorimetric formaldoxime method (Armstrong et al., 1979;\nGoto et al., 1962). These modifications were made based on the observation\nthat the amount of EDTA typically added to destroy the Fe-formaldoxime\ncomplexes that interfere with the colorimetric determination of the Mn-\nformaldoxime complexes was insufficient because of the complexation (and\npresumed competition) of this EDTA by the much higher levels of dissolved Ca2+\nand Mg2+ in our pore water samples ( 60 mM assuming a pore water salinity of\n~35). Thus it was necessary to increase the amount of EDTA added to the\nsamples so that it exceeded these Ca2+ plus Mg2+ levels.\n \nIn our method we made the formaldoxime mixed reagent by dissolving 8 g of\nhydroxylamine hydrochloride and 4ml formaldehyde (37%) in 200 ml of distilled\ndeionized water. Next we combined 0.5 ml of either a pore water sample or Mn2+\nstandard with 0.5 ml of distilled deionized water and: 50 \\u00b5l of the\nformaldoxime mixed reagent, 50 \\u00b5l of concentrated (50%) NH4OH, 50 \\u00b5l\nof a 20% hydroxylamine hydrochloride solution, and 0.2 ml of a 250 mM EDTA\nsolution. The color of the solution was allowed to develop for 20 min. and\nthen analyzed at 450 nm.

attribute NC_GLOBAL projects_0_acronym String Antarctic Shelf Sediments
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nGeneral Statement:\nThe continental shelf region west of the Antarctic Peninsula has recently undergone dramatic changes and ecosystem shifts, and the community of organisms that live in, or feed off, the sea floor sediments is being impacted by species invasions from the north. Previous studies of these sediments indicate that this community may consume much more of the regional productivity than previously estimated, suggesting that sediments are a rich and important component of this ecosystem and one that may be ripe for dramatic change. Furthermore, under richer sediment conditions, iron is mobilized and released back to the water column. Since productivity in this ecosystem is thought to be limited by the availability of iron, increased rates of iron release from these sediments could stimulate productivity and promote greater overall ecosystem change. In this research, a variety of sites across the shelf region will be sampled to accurately evaluate the role of sediments in consuming ecosystem productivity and to estimate the current level of iron release from the sediments. This project will provide a baseline set of sediment results that will present a more complete picture of the west Antarctic shelf ecosystem, will allow for comparison with water column measurements and for evaluation of the fundamental workings of this important ecosystem. This is particularly important since high latitude systems may be vulnerable to the effects of climate fluctuations. Both graduate and undergraduate students will be trained. Presentations will be made at scientific meetings, at other universities, and at outreach events. A project web site will present key results to the public and explain how this new information improves understanding of Antarctic ecosystems.\n\nTechnical Description of Project:\nIn order to determine the role of sediments within the west Antarctic shelf ecosystem, this project will determine the rates of sediment organic matter oxidation at a variety of sites across the Palmer Long Term Ecosystem Research (LTER) study region. To estimate the rates of release of iron and manganese from the sediments, these same sites will be sampled for detailed vertical distributions of the concentrations of these metals both in the porewaters and in important mineral phases. Since sediment sampling will be done at LTER sites, the sediment data can be correlated with the rich productivity data set from the LTER. In detail, the project: a) will determine the rates of oxygen consumption, organic carbon oxidation, nutrient release, and iron mobilization by shelf sediments west of the Antarctic Peninsula; b) will investigate the vertical distribution of diagenetic reactions within the sediments; and c) will assess the regional importance of these sediment rates. Sediment cores will be used to determine sediment-water fluxes of dissolved oxygen, total carbon dioxide, nutrients, and the vertical distributions of these dissolved compounds, as well as iron and manganese in the pore waters. Bulk sediment properties of porosity, organic carbon and nitrogen content, carbonate content, biogenic silica content, and multiple species of solid-phase iron, manganese, and sulfur species will also be determined. These measurements will allow determination of total organic carbon oxidation and denitrification rates, and the proportion of aerobic versus anaerobic respiration at each site. Sediment diagenetic modeling will link the processes of organic matter oxidation to metal mobilization. Pore water and solid phase iron and manganese distributions will be used to model iron diagenesis in these sediments and to estimate the iron flux from the sediments to the overlying waters. Finally, the overall regional average and distribution of the sediment processes will be compared with the distributions of seasonally averaged chlorophyll biomass and productivity.
