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 removal of carbon dioxide from the atmosphere by the marine biological pump is a key
regulator of Earth's climate; however, the ocean also serves as a large source of nitrous …

Based on four cruises covering a seasonal cycle in 2009–2011, we examined the impact of
the Kuroshio intrusion, featured by extremely oligotrophic waters, on the nutrient inventory in …

The impacts of anthropogenic nitrogen (N) deposition on the marine N cycle are only now
being revealed, but the magnitudes of those impacts are largely unknown in time and space …

To test the hypothesis that particle composition has a stronger influence on the community
structure of particle‐attached than free‐living bacteria, elemental (C/N, δ13C, and δ15N) …

Nutrients from depth have been hypothesized as a primary source of new nutrients that
sustain new productivity in oligotrophic oceans; however, the flux is challenging to quantify …

Abstract Dual isotope nitrate (NO 3−) analysis was performed on the western coast of
Guangdong Province to investigate seasonal changes in the main nitrate sources and their …

Deep ocean microorganisms consume particulate organic matter that is produced in the
surface ocean and exported to deeper depths. Such consumption not only enriches …

Nitrogen (N) transport from terrene to river water is a major source of N in estuarine water,
contributing to eutrophication, harmful algal blooms and hypoxia. However, there is a lack of …

Eutrophication-induced water deoxygenation occurs continually in coastal oceans, and
alters community structure, metabolic processes, and the energy shunt, resulting in a major …
