Supporting Stations:  Palmer Station
Research Locations:  Western Antarctic Peninsula / Litchfield and Galindez Islands

Project Description:
This project will assess response of carbon accumulation in moss peatbanks to climate changes in the last 1,000 years in the Antarctic Peninsula (AP). The overall goal is to document the formation ages and temporal changes in these peat-forming ecosystems in response to climate warming and ice retreat in an ice-dominated region. To that end, researchers will target the most recent preindustrial warm period, the Medieval Warm Period about 800 years ago, and the recent and ongoing warming interval over the last several decades. The high-resolution time series of ecosystem and climate changes that they will develop will help put the observed recent changes into a long-term context, and help bridge process-level understanding across decadal, centennial and millennial time scales. The researcher's approach is to evaluate the outcomes of past “natural climate warming experiments” that have occurred on the Antarctic Peninsula to better understand polar ecosystem responses to climate change in the past and future.

Field Season Overview:
Four field team members will sail to the Antarctic Peninsula on the ARSV Laurence M. Gould. They will spend part of their time at Palmer Station, and part at the Ukraine station, Vernadsky. They will use Zodiacs to observe and collect moss, peat and other samples from Litchfield, Galindez, and various other islands. Samples will be returned to the home institution for further study.

Deploying Team Members:

  • David Beilman (Co-PI)
  • Julie Loisel
  • Mary Tardona
  • Zicheng Yu (PI)
