Almost the entire seafloor is covered with sediments that can be more than 10 000 m thick
and represent a vast microbial ecosystem that is a major component of Earth's element and …

Sedimentary organic matter provides carbon substrates and energy sources for
microorganisms, which drive benthic biogeochemical processes and in turn modify the …

Dissolved organic matter (DOM) plays a crucial role in the coastal carbon cycle. However,
eutrophication-induced algal blooms and lateral transport from connected tidal marshes may …

Electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass
spectrometry (FT-ICR MS) has been widely used for molecular characterization of dissolved …

Dissolved organic matter (DOM) exchange in the sediment-water interface of estuaries is
essential for the global elemental cycle. To clarify the interface DOM processing, this study …

Molecular characteristics of natural organic matter (NOM) and their potential connections to
arsenic enrichment processes remain poorly understood. Here, we examine dissolved …

High levels of geogenic ammonium in groundwater is a highly neglected nitrogen pool in
coastal aquatic systems. Although organic matter (OM) mineralization is known to …

Dissolved organic matter (DOM) is a crucial controlling factor in mobilizing arsenic.
However, direct delineations of DOM regarding both optical properties and molecular …

Fungi are ubiquitous in the ocean and hypothesized to be important members of marine
ecosystems, but their roles in the marine carbon cycle are poorly understood. Here, we use …

Elevated concentration levels of geogenic ammonium in groundwater arise from the
mineralization of nitrogen-containing natural organic matter in various geological settings …
