Presentation Title:
Peat Accretion Rates, Carbon Storage, and Sustainability of Marshes in the Sacramento-San Joaquin Delta, California.

Desription of Presentation:
This presentation describes research in the Sacramento-San Joaquin Delta on peat formation and carbon storage processes throughout the past 7000 years. Using radiocarbon dating, we determined the age of peat deposits and used this information to construct age-depth models for three marshes. Next we estimated the entire history of peat accretion rates in these marshes and compared these rates to current and future rates of sea-level rise.

Presenter Name & Contact Info:
Judith Z. Drexler Wetland Ecologist, U.S. Geological Survey, California Water Science Center, Sacramento, CA

Presenter's Biography:
I am a wetland ecologist who has studied peatlands for almost twenty years. My dissertation work was in groundwater-fed fens and now I study tidal marshes. I have worked with the USGS for 8 years and before that with the Forest Service in Honolulu, HI. My current research interests are focused on wetland sustainability, peat formation processes, and the use of peat as an archive of environmental change.

Recommended Reading:

  • This research is part of the Rates and Evolution of Peat Accretion through Time (REPEAT) in the Delta project. We will soon have a web site with our new products posted. In the meantime, if you would like more information please contact me at jdrexler@usgs.gov
