Methane Working Group
Time and Location: December 7 and 8, 2019, hosted at the NASA Ames Research Center, Moffett Field, California
Overarching goal of CH4 working group: Improve predictions of methane emissions from coastal wetlands. Specifically, we aim to compile all methane flux data from coastal habitats (not mangroves) in the CONUS to parameterize and validate a set of nested process-based CH4 models.
- How well can we predict methane emissions from coastal wetlands? In other words, what are the main sources of error? What types of wetlands are the most difficult to model (along spectrum of salinity, disturbance/age, plant community etc.)
- What data streams are needed to improve our predictions?
- Can our process-based models predict interannual variability? If not, why? How does this influence predictions of CH4 budgets in the future?
- What guidance can we give to the science and management communities based on these efforts?
The Coastal Carbon Research Coordination Network (CCRCN) is dedicated to providing a welcoming and supportive environment for all people, regardless of background or identity. However, we recognise that some groups in our community are subject to historical and ongoing discrimination, and may be vulnerable or disadvantaged. Membership in such a specific group can be on the basis of characteristics such as gender, sexual orientation, disability, physical appearance, body size, race, nationality, sex, colour, ethnic or social origin, pregnancy, citizenship, familial status, veteran status, genetic information, religion or belief, political or any other opinion, membership of a national minority, property, birth, age, or choice of text editor. We do not tolerate harassment of participants on the basis of these categories, or for any other reason.
Harassment is any form of behaviour intended to exclude, intimidate, or cause discomfort. Because we are a diverse community, we may have different ways of communicating and of understanding the intent behind actions. Therefore we have chosen to prohibit certain forms of behaviour in our community, regardless of intent. Prohibited harassing behaviour includes but is not limited to:
- Written or verbal comments which have the effect of excluding people on the basis of membership of a specific group listed above
- Causing someone to fear for their safety, such as through stalking, following, or intimidation
- The display of sexual or violent images
- Unwelcome sexual attention
- Nonconsensual or unwelcome physical contact
- Sustained disruption of talks, events or communications
- Incitement to violence, suicide, or self-harm
- Continuing to initiate interaction (including photography or recording) with someone after being asked to stop
- Publication of private communication without consent
Behaviour not explicitly mentioned above may still constitute harassment. The list above should not be taken as exhaustive but rather as a guide to make it easier to enrich all of us and the communities in which we participate. All CCRCN interactions should be professional regardless of location: harassment is prohibited whether it occurs on- or offline, and the same standards apply to both.
Enforcement of the Code of Conduct will be respectful and not include any harassing behaviors. Any changes to the meaning of this Code of Conduct must be approved by majority vote of the CCRCN Steering Committee. CCRCN working group and network members will be informed of these changes and any concerns that are raised will be discussed by the Steering Committee.
Thank you for helping make this a welcoming, friendly community for all.

Members involved in CCRCN collaborations are entitled to their own intellectual property, and distinctions should be made clarifying what is individual property versus group property. Here are the principles to which the Soil Carbon working group adheres to:
- Anything developed as a group is collective intellectual property (IP) that members collectively decide what to do with (such as assigning a creative commons license or signing rights over to a publisher).
- Anything developed outside the group is the intellectual property of the individual who produced it or their institution (whichever is applicable).
- Any outside IP needs to be properly acknowledged and cited in CCRCN work.
- All members agree not to share unpublished work outside the group without explicit permission to do so.
- At the end of the project, working group members commit to making code and derivative data products that the group developed collectively open and available as part of data releases associated with papers and reports.
- The working group will publish products that only include data that is or will be publicly available (via repository) at the time of working group publication.
