Nitrogen (N) is one of the primary nutrients required to build biomass and is therefore in high
demand in aquatic ecosystems. Estuaries, however, are frequently inundated with high …

Coastal hypoxia is an increasingly recognized environmental issue of global concern to both
the scientific community and the general public. We assessed the relative contributions from …

The heavily human-perturbed coastal oceans are hotspots of nitrous oxide (N2O) emission
to the atmosphere. The processes underpinning the N2O flux, however, remain poorly …

Present-day estimations of global nitrogen loss (N-loss) are underestimated. Commonly, N-
loss from rivers is thought to be caused by denitrification only in bed-sediments. However …

Nitrification is simulated in existing water quality models by multiplying the rate with the
attenuation factors for water temperature and dissolved oxygen. The effect of pH, substrates …

Coastal mangrove swamps play an important role in nutrient cycling at the land-ocean
boundary. However, little is known about the role of periodic seawater-groundwater …

Phytoplankton assimilation and microbial oxidation of ammonium are two critical conversion
pathways in the marine nitrogen cycle. The underlying regulatory mechanisms of these two …

Coastal oceans, known as the major nitrous oxide (N 2 O) source to the atmosphere, are
increasingly subject to eutrophication and concurrent near-bottom hypoxia. The natural …

The reactive nitrogen (N) emitted from continents significantly perturbs the pristine N cycle
around the land-ocean boundary resulting in eutrophication and hypoxia. As nutrients are …

As a key biogeochemical pathway in the marine nitrogen cycle, nitrification (ammonia
oxidation and nitrite oxidation) converts the most reduced form of nitrogen–ammonium …
