Carbon and nitrogen uptake in the South Pacific Ocean: evidence for efficient dinitrogen fixation and regenerated production leading to large accumulation of dissolved organic matter in nitrogen-depleted waters - Raimbault, GarciaRaimbault, P. and Garcia, N.: Carbon and nitrogen uptake in the ...
iron cycle. Instead of focusing on dust as the major iron source and emphasizing iron’s tight biogeochemical coupling to major nutrients, a more complex and diverse picture of the sources of iron, its cycling processes and intricate linkages with the ocean carbon and nitrogen cycles has emerged...

Here, we examine how microorganisms with key roles in the ocean carbon and nitrogen cycles may respond to these changes in the Earth's largest ecosystem. Some functional groups such as nitrogen-fixing cyanobacteria and denitrifiers may be net beneficiaries of these changes, while others such as ...
Carbon Dioxide in the Ocean and Atmosphere Carbon dioxide (CO 2 ) is considered a trace gas in the atmosphere because it is much less abundant than oxygen or nitrogen. However, this trace gas plays a vital role in sustaining life on Earth and in controlling the Earth's climate by trapping...
The biosphere's uptake and storage of carbon have the potential to either slow or amplify global warming providing a carbon-climate feedback to global warming. The interactions between carbon (C) and the nutrient cycles, especially nitrogen (N) and phosphorus (P), are important to the biosphere...
This article outlines the isotope systematics of the major processes in the ocean nitrogen (N) cycle, their impact on the isotopic compositions of the major N reservoirs in the ocean, and how the N isotopes in the modern ocean and sedimentary record may record current N fluxes and past change...

Siderophores were detected by elemental and organic mass spectrometry. Different carbon sources were added to seawater to maximise siderophore diversity. Siderophores were produced by mixed microbial populations from the Atlantic Ocean. 23 different siderophores were detected in the study.关键词:...
