This model is a replica of a core retrieved in the Antarctic Peninsula on ODP Expedition 178. It shows seasonal layers (laminae) composed of different diatoms species that were deposited during the late Holocene and provides evidence for the changing climate and glacial retreat that took place in the region after the last ice age. This core section also contains a drop stone.

How to use the core model with students:

  1.      Revivew the Palmer Deep Core Information*.
  2.      Use What You See Is What You Get< with the core model instead of or along with the core photos referenced in the activity.
  3.      Use A Reader’s Guide to Climate Change< with articles from Climate Change Highlights*.
  4.      Reading the Deglacial seasonal and sub-seasonal diatom record from Palmer Deep, Antarctica* article.
