This working group will bring together 45 experts working on marine N2 fixation in a coordinated effort to improve understanding of the distribution and functioning of marine N2 fixers in the world ocean. The objective of the working group is to synthesise the current state of knowledge on the environmental controls of marine N2 fixation, and establish a consensus on current concepts and best practices in experimental, microbial and modelling research on marine N2 fixation.

The multidisciplinary team will identify knowledge gaps, taking account of the potential for past and future global change and linkages to the carbon cycle, and further promote a collaborative future research agenda to be addressed via large integrated international programmes. This will enable the group to strengthen and consolidate collaborations initiated at the initial workshop and help develop a consensus on current understanding of marine N2 fixation. The synthesis of the current state of knowledge and more detailed reviews on specific topics will be published in a special issue peer reviewed literature. The final outcome will be a roadmap, including strategies for future collaborative research projects under European joint research funding programmes.

The working group will act as a nucleus for a new research agenda for improving the understanding of marine diazotrophs and biogeochemistry under on-going anthropogenic forcing. Bringing together experts working on marine N2 fixation with a multitude of tools covering diverse spatial and temporal scales will have an immediate impact on the sharing of ideas and inform the planning of future joint research. 

The workshop will be held back-to back with the 2016 Ocean Sciences Meeting.

The workshop was held on 25th February 2016, in New Orleans, USA, back-to-back with the Ocean Sciences meeting 2016, bringing together 30 marine scientists from 11 countries to discuss current knowledge and pitfalls on marine N2-fixation. Plenary short overview presentations were followed by an open discussion on research priorities and open questions. The wide range of expertise – from molecular biology to global biogeochemistry and from cell to global scales modelling – stimulated dynamic and cross-disciplinary discussions.

The workshop promoted scientific and technical exchange within an interdisciplinary and comprehensive research environment, allowing for the strengthening and consolidation of international collaborations. The group is currently working towards a collection of review, perspectives and original papers to define the current state on knowledge and uncertainties, to be published in the open access journal, within a N2 fixation dedicated Research Topic initiated and managed by the workshop organizers. To date, 18 potential contributions have been submitted from workshop attendees and other researchers who could not attend.
