The nitrogen (N) cycle involves a set of N compounds transformed by plants and microbes.
Some of these N compounds, such as nitrous oxide (N 2 O) or nitrate (NO 3−), are …

The marine nitrogen cycle is a complex web of microbially mediated reactions that control
the inventory, distribution, and speciation of nitrogen in the marine environment. Because …

Ocean acidification produced by dissolution of anthropogenic carbon dioxide (CO2)
emissions in seawater has profound consequences for marine ecology and …

Nitrification plays an important role in marine biogeochemistry, yet efforts to link this process
to the microorganisms that mediate it are surprisingly limited. In particular, ammonia …

The flux of organic material sinking to depth is a major control on the inventory of carbon in
the ocean. To first order, the oceanic system is at equilibrium such that what goes down must …

To better constrain the dynamics of the dissolved organic nitrogen (DON) pool and the role
of N2 fixation in the nitrogen cycle at the Bermuda Atlantic Time‐series Study (BATS) site …

Nitrification is the process whereby ammonium (NH4 þ) is oxidized to nitrite (NO2 À) and
then to nitrate (NO3 À). It thus links the most oxidized and most reduced components of the …

Although increasing atmospheric nitrous oxide (N2O) has been linked to nitrogen loading,
predicting emissions remains difficult, in part due to challenges in disentangling diverse …

Over the last 30 years, immense progress has been made in understanding the global
significance of marine nitrogen (N~ 2~) fixation. Development of enzymological, isotopic and …

In order to provide biological systematics from which to interpret nitrogen (N) and oxygen (O)
isotope ratios of nitrate (15N/14N, 18O/16O, respectively) in the environment, we previously …
