B34B:
The Current and Future Nitrogen Cycle: From Microbes to the Global Ocean III Posters


Session ID#: 9488

Session Description:
New developments in nitrogen biogeochemistry were the subject of a session at the Ocean Sciences Meeting thirty years ago. Since then there have been many unexpected discoveries and new tools have been developed not only for studying the nitrogen cycle, but also for integrating the nitrogen cycle with other biogeochemical cycles and for extrapolating over space and time. This session will cover all aspects of the nitrogen cycle, from unanswered questions remaining from 3 decades ago, to newly discovered processes and features of nitrogen cycling in the global ocean. Speakers will be encouraged not only to talk about their recent work and discoveries, but to reserve time and present a slide on what they see as the future important and significant questions for understanding the global ocean nitrogen cycle, its biogeochemical interactions and impacts of global climate change.
