Marine dissolved organic matter (DOM) contains more carbon than the combined stocks of
Earth's biota. Organisms in the ocean continuously release a myriad of molecules that …

The biogeochemical cycling of soil organic matter (SOM) plays a central role in regulating
soil health, water quality, carbon storage, and greenhouse gas emissions. Thus, many …

Groundwater comprises 95% of the liquid fresh water on Earth and contains a diverse mix of
dissolved organic matter (DOM) molecules which play a significant role in the global carbon …

Dissolved organic matter affects fundamental biogeochemical processes in the soil such as
nutrient cycling and organic matter storage. The current paradigm is that processing of …

Each different molecular elemental composition—eg, CcHhNnOoSs—has a different exact
mass. With sufficiently high mass resolving power (m/Δ m 50%≈ 400,000, in which m is …

The structural elucidation of small molecules using mass spectrometry plays an important
role in modern life sciences and bioanalytical approaches. This review covers different soft …

More than 90% of the global ocean dissolved organic carbon (DOC) is refractory, has an
average age of 4000–6000 years and a lifespan from months to millennia. The fraction of …

Coastal oceans link terrestrial and marine carbon cycles. Yet, carbon sources and sinks in
these biomes remain poorly understood. Here, we explore the dynamics of dissolved …

High-performance, non-target, high-resolution organic structural spectroscopy was applied
to solid phase extracted marine dissolved organic matter (SPE-DOM) isolated from four …

Soils, sediments, freshwaters, and marine waters contain natural organic matter (NOM), an
exceedingly complex mixture of organic compounds that collectively exhibit a nearly …
