attribute NC_GLOBAL acquisition_description String Laboratory analysis\n \nNH4+ and NO3- concentrations were measured at the University of Washington\nMarine Chemistry Lab (methods from UNESCO 1994). Concentration values from\n2011 were corrected for rain dilution using the change in salinity measured\nover the incubation period assuming no addition of NH4+ or NO3- to the pools\nfrom the rainfall.\\u00a0\n \nNH4+ isotopic composition was measured according to a modified version of\nZhang et al. (2007) after isotope dilution to less than 500\\u2030 to prevent\nisotopic contamination of the natural abundance-level mass spectrometer\nsystem. Briefly, NH4+ is oxidized to nitrite using hypobromite then reduced to\nN2O using acetic acid buffered sodium azide before analysis on an isotope\nratio mass spectrometer (IRMS). In modification of the prior method, pre-\nexisting NO2- was removed prior to hypobromite addition by reaction with\nsulfamic acid. To a 20 mL sample volume, 340 \\u00b5L 20 mmol L-1 sulfamic acid\nand 10 \\u00b5L 10% HCl was added and allowed to react for 12 hours at room\ntemperature. A second improvement was the addition of 6 mol L-1 HCl to reduce\nthe pH of the sample below 7 prior to the addition of an azide-100% acetic\nacid reagent. Isotope determinations were made at U. Massachusetts Dartmouth\nusing a GV IsoPrime IRMS, a custom purge-trap sample preparation system, and a\nCTC PAL autosampler. Reproducibility was better than \\u00b1 0.5\\u2030. \\u00a0\n \nFilters and algal samples were dried at 60\\u00b0C for 48 h and elemental and\nisotopic analyses were made at the University of Chicago and at Yale\nUniversity. Samples were run using a Costech 4010 Elemental Analyzer\ncombustion system coupled to a Thermo DeltaV Plus IRMS via a Thermo Conflo IV\ninterface (University of Chicago), or using the same Elemental Analyzer\ncoupled to a Thermo DeltaXP Advantage IRMS via a Thermo Conflo III interface\n(Yale University). \\u00a0Reproducibility was better than \\u00b1 0.1\\u2030.\n\\u00a0

attribute NC_GLOBAL projects_0_acronym String Regenerated Nitrogen
attribute NC_GLOBAL projects_0_description String We described patterns of nitrogen isotopes that change over spatial gradients of animal abundance, with isotopic enrichment patterns consistent with a role for animal excretion (Pfister et al, ms). We have quantified the microbes associated with intertidal mussels with metagenomics (Pfister et al. 2010 and 16S rRNA sequencing of the v4 region (Pfister et al, submitted). We used a novel experimental approach in which stable isotope tracers were added to exposed tidepools utilizing them as temporary mesocosms to quantify N transformation rates (Pather et al.,L&O). Large tracer signals were observed over the typical 4-5 hr experimental period in both the dilution of the isotope label in its added form (NH4+ or NO3-) and the appearance of the label in products (e.g. NO2-) The primary advantage was that all members of community participated in the experiment allowing us to recognize the complexity of nitrogen cycling in this system. This funding also supported long-term global change research on Tatoosh Island (Wootton & Pfister 2012 ).   \nProject Summary From Original Proposal\nA fundamental and persistent question in a multitude of ecosystems is the extent to which new versus regenerated nutrients support ecosystem productivity. In coastal marine systems, nitrate derived from upwelling (=new nitrogen) and ammonium regeneration in coastal waters and sediments (=regenerated nitrogen) are major nitrogen sources that fuel coastal ocean productivity. Because inorganic nitrogen availability clearly regulates production in a large number of areas, understanding nitrogen supply is essential. In open coast regions away from river mouths, nitrate inputs are determined by large-scale physical processes promoting upwelling of deep, nutrient-rich water including wind direction and intensity. In contrast, regenerated nitrogen (mainly ammonium) is generally the result of local animal and microbial processes. Along marine rocky shores, where upwelling is typically used as a proxy for productivity, we know very little about the dynamics of regenerated nutrients and their potential contribution to productivity at larger scales; only upwelling is typically used as a proxy for productivity. Associations of the abundant California mussel, Mytilus californianus, with water nutrients, algal productivity, stable isotope signatures, and microbial genetics indicate potentially strong regeneration of nitrogen by these animals and suggests an important secondary role of nitrifying microbes affiliated with these animals.\nWe propose collaborative work to quantify the relative contribution of regenerated nitrogen on rocky shores through censuses and experiments across a gradient of mussel abundance. We will use stable nitrogen and oxygen isotopes of ammonium, nitrite, and nitrate to disentangle the contribution of different biological processes versus upwelling to the nitrogen supply and uptake of rocky shore regions. This includes both natural abundance and tracer addition studies.\n \nRelevant References:\n2010. Pfister, C. A., F. Meyer, D. A. Antonopoulos.

attribute NC_GLOBAL summary String We evaluated the role of mussels by adding 15N-labeled NH4+ to an assemblage\nof tidepools where they were either present at natural abundance levels, or\nabsent through manual removal. \\u00a0The role of phototrophs was separately\nexamined by conducting these experiments both during the day and at night.\n\\u00a0The tidal height of pools varied between 1.2 to 1.5 m above Mean Lower\nLow Water (MLLW). Tidepools were thus isolated from each other as well as the\nnearshore environment during the low tide period when experiments were\nconducted. Each experiment included 4 to 5 mussel removal (MR) tidepools\n(since 2002) and 4 to 5 mussel control (MC) tidepools with natural mussel\ndensities. \\u00a0In June 2010, we performed daytime NH4+ tracer experiments\nand in August 2010 nighttime experiments using the same tidepools. The\nfollowing year (July 2011) these experiments were repeated with the addition\nof bottle incubations (see below) to evaluate the effects of suspended\ntidepool components and extended sampling for 6 days after the initial 15N\naddition to test for long-term retention of NH4+. \\u00a0During the 2011\nexperiments, unforeseen rain reduced the salinity in some pools by up to 51%,\nand we have attempted to correct for the expected dilution of NH4+ in our\ntidepool rate calculations.\n \nBecause isotope enrichment levels were relatively low, we used the\nconventional delta notation instead of atom% to describe variations in 15N\nenrichment (where delta-15NH4+ = {(15N:14N sample \\u00f7 15N:14N standard)\n-1}\\u00d71000\\u2030, where the standard is atmospheric N2. \\u00a0Tracer\nlabeled ammonium chloride (15NH4Cl) was added to the pools to approximate a\n1000\\u2030 enrichment in 2010 (doubling the 15N-NH4+ concentration) and a\n2000\\u2030 enrichment in 2011(tripling the 15N-NH4+ concentration). 15N\nnatural abundance is only 0.365% and these tracer additions thus had a\nnegligible effect on the overall NH4+ concentrations increasing them by only\n~0.4% and ~0.8%, respectively. Tidepool volumes were estimated\nspectrophotometrically using varying concentrations of food dye (Pfister\n1995). Together with estimates of NH4+ concentration (from 2009 data), we\nestimated the tracer addition required to achieve the targeted 15N\nenrichments. However, the actual initial enrichments varied substantially,\n684.4 - 2406.4\\u2030 in 2010 and 781.4 - 3880.2\\u2030 in 2011, likely due to\nerror in tidepool volume estimation and natural variations in initial NH4+\nconcentrations. Fortunately, we sampled immediately following each tracer\naddition allowing for the determination of the true initial 15N enrichment.\n\\u00a0\n \nPrior to tracer addition at ebb tide, 100 mL of tidepool water was syringe-\nfiltered (Whatman GF/F) into separate HDPE bottles for natural abundance\n15NH4+ and concentration determination. \\u00a0To each pool, tracer 15NH4+ was\nthen added and distributed by stirring with a stick. Water samples were\nimmediately collected for measuring initial 15N enrichment and subsequently at\n2, 4, and 6 hour intervals to determine isotope and concentration time\ncourses. All water samples were frozen until analysis. Tidepool oxygen, pH,\nand temperature (Hach HQ4D) were also collected at ~ 2 h intervals throughout\nthe experiment.\n \nIn 2011 we also assessed the contribution of the suspended microbial community\nto NH4+ cycling by enclosing tidepool water in a 250 mL transparent\npolycarbonate incubation bottle. Following tracer addition, the bottle was\nfilled, then left to float in the tidepool for the duration of the experiment.\nSamples from bottles were filtered as described both immediately after\ncontainment and at the end of the experiment (~6 h later).\n \nWe assessed macroalgal contribution to NH4+ removal by transplanting two\ntidepool-dwelling algae species. \\u00a0Prionitis sternbergii were sampled 2\nweeks prior to the experiment for baseline natural abundance 15N values and\ntransplanted into the pools with Z-Spar Epoxy (Pfister 2007). On the day of\nthe experiment, the red-alga, Corallina vancouveriensis from a single source\npatch, was also sampled for 15N natural abundance, inserted into pieces of\nStyrofoam, and floated in each pool.\n \nAt the end of each experiment (~6 h sampling point), we sampled tidepool\nparticulate organic material (POM) by filtering through combusted GF/F filters\nuntil they clogged (~ 600 mL), comparing these samples with POM similarly\nsampled from the immediate nearshore. \\u00a0Floating Corallina spp. samples\nwere collected into clean Eppendorf tubes, and similar sized pieces of\nPrionitis spp. were collected from each pool into clean foil packets.\\u00a0  \n We evaluated the extent of longer-term 15N tracer retention in 2011 by\nsampling tidepool water, POM and transplanted Prionitis 1, 3, and 6 days\nfollowing tracer addition. We sampled at ebb tide and at again at slack water\njust prior to high tide on the first day after tracer addition (that is, 24 h\nlater) and at slack water prior to high tide on Day 3 and 6.\\u00a0\n \nRelevant References:\n \n2014\\.
