Soil Carbon Working Group

The Coastal Carbon Network (CCN) 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 CCN 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 CCN Steering Committee. CCN 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 CCN 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 CCN 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.

Dr. E. Fay Belshe Fay Belshe headshot

Dr. Fay Belshe is interested in how organic matter (OM) forms and decays within soils of coastal vegetated ecosystems, specifically seagrasses. Her work explores the mechanisms and controls governing OM persistence and residence times, with a focus on how living OM (plants, microbes), dead OM, and soil properties interact to determine the dynamic cycling of carbon under a constant and changing climate.

 
 
 
 
 
Dr. Brandon Boyd

Brandon Boyd headshotDr. Brandon Boyd’s research is focused on physical and biological processes in tidal marshes and how those marshes connect with estuary or coastal system. Dr. Boyd uses his expertise in radionuclide chronology and tracers to identify and quantify processes in those systems. His projects are often focused on determining how vertical accretion in restored wetlands may differ from their natural neighbors and designing marsh restorations with balance between storm resilience and ecologic benefit.

Lauren BrownLauren Brown headshot

Lauren completed her MA in Geography at UCLA and is finishing her PhD in the same program working with Dr. Glen MacDonald. While at UCLA she has collected sediment cores from over 10 marshes, spanning the California coast from Humboldt Bay to Tijuana River Estuary. She uses these sediment cores to investigate vulnerability to SLR, carbon storage, and long-term environmental change. Methods she has employed include radiometric dating, LOI, grain size analysis, EA, XRF, macro charcoal, and biological proxy data. Her final year of the PhD will be dedicated to improving her data management and analyses skills.

Dr. Ron CorstanjeRon Corstanje headshot

Dr. Ron Corstanje is a professor of Data Sciences at Cranfield and Head of the Centre for Environmental and Agricultural Informatics. He specialises in the application of spatio-temporal models to understand the nature and behaviour of natural systems and processes. Ron is interested in the application of (spatial) modelling tools to understand the structure and function of environmental systems and processes. Environmental systems are complex, and this expresses itself as complex but determinable spatiotemporal patterns. The application of these approaches has led to significant advances in understanding on the spatial dynamics of ecosystem services, across systems including wetlands. Another key area in which these techniques have proven invaluable is in the area of resilience as applied to ecological systems, allowing significant insights into the nature and functioning of resilience. Both these areas have significant societal significance, in helping inform how to infer resilience in the natural and man-made systems on which we depend, but also in how to design and plan the environment to retain the benefits from the natural capital inherent in our greenspaces.

 
Dr. Meagan GonneeaMeagan Gonneea

Dr. Meagan Gonneea is a research scientist at the US Geological Survey Woods Hole Coastal and Marine Science Center. She utilizes a suite of geochemical tools, including naturally occurring radioisotopes in the Uranium-Thorium decay series, to understand both the magnitude and rate of change within coastal ecosystems. In particular, Meagan is interested in how salt marshes have responded to more than a century of accelerating sea level rise, with a focus on their ability to store carbon and dynamically build elevation. She combines historical ecosystem information, gleaned from analysis of salt marsh peat, with modern environmental drivers to constrain future ecosystem responses.
