Bogs and Marshes

    Overall, I think this is a good start, but it is still an outline so you have quite a few questions to answer. I think pictures of each of the processes and structures would be helpful (Taryn Lausch 5/29/20).

    Introduction 

    [insert photo here]

    Intro to bogs and marshes

    - what are they? why are they important? Functions of bog/marshes? What are the answers to these questions?

    - General location of bogs/marshes with relation to other environments

      [insert satellite view/sketch here]

    - Add in some example locations (I would choose famous bogs and marshes, or ones in California close to Davis)

     

    Sediment Transport Processes

    Flow characteristics within bogs and marshes What are the flow characteristics? Generally, they have very low flow and mostly accumulate organic matter, so you want to be sure to include the growth of plants even though that isn't specifically "sediment transport" - I now see that you have this in the characteristics of deposited sediment, which is good.

    What kind of sediment carried through this environment?

    - sed structures and examples There is a huge amount of bioturbation from roots, etc. However, the details vary depending on how much oxygen gets into the sediment.

    Pictures of each of these structures would be great

    Characteristics of Deposited Sediments

    What grain sizes are typical of this environment?

    Relatively low flow velocity here

    - what does this mean about deposited seds

    - organic material

    - carbon sink

    Sed structures

    [insert examples of sed structures in this environment]

    Vertical facies for environment

    - changes through time?

    Case Studies and Significance

    Discuss some relevant studies

    -maybe try to link in current environmental issues? e.g. loss of habitats, marsh rot

    Studies that are closer to home/in California might be useful, as they give students an opportunity to go and visit them

    Additional Reading

    Some links for additional reading if reader is interested in topic

    Links to marsh restoration projects in the Delta would be interesting
