  • Glaciers as a source of anc... Glaciers as a source of ancient and labile organic matter to the marine environment
    HOOD, Eran; FELLMAN, Jason; SPENCER, Robert G. M ... Nature (London), 12/2009, Letnik: 462, Številka: 7276
    Journal Article
    Recenzirano

    Riverine organic matter supports of the order of one-fifth of estuarine metabolism. Coastal ecosystems are therefore sensitive to alteration of both the quantity and lability of terrigenous dissolved ...

  • Photochemical and microbial... Photochemical and microbial degradation of dissolved lignin phenols: Implications for the fate of terrigenous dissolved organic matter in marine environments
    Hernes, Peter J.; Benner, Ronald Journal of Geophysical Research - Oceans, September 2003, Letnik: 108, Številka: C9
    Journal Article
    Recenzirano
    Odprti dostop

    Molecular level characterizations of dissolved lignin were conducted in Mississippi River plume waters to study the impact of various removal mechanisms (photooxidation, microbial degradation, and ...

  • Illuminated darkness: Molec... Illuminated darkness: Molecular signatures of Congo River dissolved organic matter and its photochemical alteration as revealed by ultrahigh precision mass spectrometry
    Stubbins, Aron; Spencer, Robert G. M.; Chen, Hongmei ... Limnology and oceanography, July 2010, Letnik: 55, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    Congo River water was filtered and then irradiated for 57 d in a solar simulator, resulting in extensive photodegradation of dissolved organic matter (DOM). Whole-water (i.e., unfractionated) DOM was ...

  • Molecular Trickery in Soil ... Molecular Trickery in Soil Organic Matter: Hidden Lignin
    Hernes, Peter J; Kaiser, Klaus; Dyda, Rachael Y ... Environmental science & technology, 08/2013, Letnik: 47, Številka: 16
    Journal Article
    Recenzirano

    Binding to minerals is one mechanism crucial toward the accumulation and stabilization of organic matter (OM) in soils. Of the various biochemicals produced by plants, lignin-derived phenols are ...

  • Lignin biogeochemistry: fro... Lignin biogeochemistry: from modern processes to Quaternary archives
    Jex, Catherine N.; Pate, Gary H.; Blyth, Alison J. ... Quaternary science reviews, 03/2014, Letnik: 87
    Journal Article
    Recenzirano

    Lignin has been analysed as a proxy for vegetation change in the Quaternary science literature since the early 1990s in archives such as peat, lakes, and intertidal and marine sediment cores. ...

  • Seasonal and spatial variab... Seasonal and spatial variability in dissolved organic matter quantity and composition from the Yukon River basin, Alaska
    Spencer, Robert G. M.; Aiken, George R.; Wickland, Kimberly P. ... Global biogeochemical cycles, December 2008, Letnik: 22, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    The seasonal and spatial variability of dissolved organic matter (DOM) quantity and chemical composition were investigated in the Yukon River basin of Alaska, United States, and northwestern Canada. ...

  • Fractionation of lignin dur... Fractionation of lignin during leaching and sorption and implications for organic matter “freshness”
    Hernes, Peter J.; Robinson, Amelia C.; Aufdenkampe, Anthony K. Geophysical research letters, September 2007, Letnik: 34, Številka: 17
    Journal Article
    Recenzirano
    Odprti dostop

    Much of what we know about the cycling of terrigenous organic matter (OM) in freshwater and marine systems can be attributed to evidence derived from biomarkers such as lignin. Here we report the ...

  • Loss of optical and molecul... Loss of optical and molecular indicators of terrigenous dissolved organic matter during long-term photobleaching
    Helms, John R.; Mao, Jingdong; Stubbins, Aron ... Aquatic sciences, 07/2014, Letnik: 76, Številka: 3
    Journal Article
    Recenzirano

    Two water samples from the Great Dismal Swamp National Wildlife Refuge with high dissolved organic matter (DOM) concentrations (51 and 121 mg C L −1 ) were subjected to ultraviolet (UV) light for up ...

  • Dissolved organic carbon bi... Dissolved organic carbon biolability decreases along with its modernization in fluvial networks in an ancient landscape
    Fellman, Jason B; Spencer, Robert G. M; Raymond, Peter A ... Ecology (Durham), September 2014, Letnik: 95, Številka: 9
    Journal Article
    Recenzirano

    The metabolism of dissolved organic carbon (DOC) along fluvial networks determines what fraction of organic matter is exported to the ocean. Although it is thought fresh rather than older DOC is ...

    Spencer, Robert G. M.; Stubbins, Aron; Hernes, Peter J. ... Journal of Geophysical Research - Biogeosciences, September 2009, Letnik: 114, Številka: G3
    Journal Article
    Recenzirano
    Odprti dostop
