Ocean deoxygenation could potentially trigger substantial changes in the composition and
reactivity of dissolved organic matter (DOM) pool, which plays an important role in the global …

Nitrite, an intermediate product of the oxidation of ammonia to nitrate (nitrification),
accumulates in upper oceans, forming the primary nitrite maximum (PNM). Nitrite …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

UCYN-A is a globally important nitrogen-fixing symbiotic microbe often found in colder
regions and coastal areas where nitrogen fixation has been overlooked. We present a 3 …

Abstract Analysis of the common and most influential natural and anthropogenic activities on
the spatiotemporal variation in nutrients at a multiannual scale is important. Eleven cruises …

Estuaries at the global scale are significant but highly uncertain sources of atmospheric
nitrous oxide (N2O), which is an intense greenhouse gas and ozone depletion agent. As the …

Deoxygenation of the ocean has been occurring over the last half century, particularly in
poorly ventilated coastal waters. In coastal and estuarine environments, both the water …

Microbial observatories can track phytoplankton at frequencies that resolve monthly,
seasonal, and multiyear trends in environmental change from short-lived events. Using 4 …

The productivity and health of our ocean hold some good solutions to the world's challenges
in socio-economy. However, climate change and waste discharge are changing the marine …
