From Mud to Molecules: What Deep Sea Sediments Can Tell Us about Past Climates

Geoffrey Eglington, Woods Hole Oceanographic Institution

This video documents how scientists, using marine algae, can study climate change in the past to help understand potential effects of climate change in the future.

Teaching Tips

  • It is common for high school science classes to study cells. This video could be used in conjunction to a unit on cells tied to current events and climate related studies.
  • Core mud samples could be analyzed with students and could teach students about the secrets that lie within... using a resource like : http://www.ldeo.columbia.edu/res/fac/CORE_REPOSITORY/RHP1.html where a repository of deep sea sediments is available to possibly use.

About the Science

  • The video explains how the marine algae Emiliania huxleyi, aka Emilia, responds chemically to temperature changes making different forms of alkenones at different temperatures. Because ocean temperature is a driver of climate, scientists can use proxy temperature differences as measured by alkenones to understand past climate changes.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Prerequisite knowledge required due to strong ties to biological processes and the biological pump and climate changes that are linked to a small marine algae.
  • This video would probably fit quite well in a marine biology or oceanography course where students would have greater access to background knowledge needed to understand the science in the video.
