Nitrogen fixation is critical for the biological productivity of the ocean, but clear mechanistic
controls on this process remain elusive. Here, we investigate the abundance, activity, and …

Nutrients limiting phytoplankton growth in the ocean are a critical control on ocean
productivity and can underpin predicted responses to climate change. The extensive …

Abstract In the North Pacific Subtropical Gyre, which is one of the largest oligotrophic
regions, there is a lack of information regarding the sources and transport of trace metals …

In regions of the nitrogen limited low latitude ocean, phosphate can also be depleted to
levels initiating stress responses in marine microbes. Here, we associate a broad region of …

Abstract The Pearl River Estuary (PRE), the largest estuary in Southern China, regulates the
fluxes of riverine trace metals into the South China Sea. However, the geochemical behavior …

Although the crucial role that dissolved trace metals (dTMs) play in both carbon cycling and
climate have been revealed over the past three decades, much about the oceanic budgets …

Proton-pump rhodopsin (PPR) in marine microbes can convert solar energy to bioavailable
chemical energy. Whereas bacterial PPR has been extensively studied, counterparts in …

Rivers are a major supplier of particulate and dissolved material to the ocean, but their role
as sources of bio-essential dissolved iron (dFe) is thought to be limited due to rapid, efficient …

A thorough understanding of the biogeochemical cycling of trace metals in the ocean is
crucial because of the important role these elements play in regulating metabolism in marine …

The material and energy exchange at the air-sea interface is an important cause of global
climate and ecological environment change. As the largest shelf margin sea in China and …
