Journal ArticleDOI
Graphical method for analysis of ultrahigh-resolution broadband mass spectra of natural organic matter, the van Krevelen diagram.
TL;DR: This work proposes and demonstrates an approach using the van Krevelen diagram that can be visualized in a way that allows for possible reaction pathways to be identified and presented, and qualitative analyses on major classes of compounds that comprise ultrahigh-resolution spectra.
Journal ArticleDOI
Bulk chemical characteristics of dissolved organic matter in the ocean
TL;DR: Tangential-flow ultrafiltration was shown to recover milligram amounts of >1000 daltons of DOM from seawater collected at three depths in the North Pacific Ocean, and polysaccharides appear to be more abundant and reactive components of seawater DOM than has been recognized.
Journal ArticleDOI
Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere

TL;DR: In this paper, the authors conducted a comprehensive intercomparison of this type (multimethod, multilab, and multisample), focusing mainly on methods used for soil and sediment BC studies.
Journal ArticleDOI
The molecularly-uncharacterized component of nonliving organic matter in natural environments

TL;DR: The origins, reactions and fates of molecularly-uncharacterized organic matter are relatively obscure, in large part because the rich vein of geochemical information that typically derives from detailed structural and stereochemical analysis is yet to be tapped.
Journal ArticleDOI
Natural photolysis by ultraviolet irradiance of recalcitrant dissolved organic matter to simple substrates for rapidbacterial metabolism
TL;DR: In this paper, leachate and humic and fulvic acid fractions of dissolved organic matter (DOM) released from senescent littoral aquatic plants were exposed to varying spectra of ultraviolet radiation as well as natural UV of sunlight over different periods of time.
