Vostok Ice Core: Excel (Mac or PC)
This activity received a gold star rating from a Panel Peer Review.
HideThis resource received a gold-star rating from a Panel Peer Review
These materials were reviewed using face-to-face NSF-style review panel of geoscience and geoscience education experts to review groups of resources addressing a single theme. Panelists wrote reviews that addressed the criteria:
- scientific accuracy and currency
- usability and
- pedagogical effectiveness
- Accept
- Accept with minor revisions
- Accept with major revisions, or
- Reject.
Following the panel meetings, the conveners wrote summaries of the panel discussion for each resource; these were transmitted to the creator, along with anonymous versions of the reviews. Relatively few resources were accepted as is. In most cases, the majority of the resources were either designated as 1) Reject or 2) Accept with major revisions. Resources were most often rejected for their lack of completeness to be used in a classroom or they contained scientific inaccuracies.

Summary
Students use Excel to graph and analyze Vostok Ice core data (more info) (160,000 years of Ice core data from Vostok Station). Data includes ice age, ice depth, carbon dioxide, methane, dust, and deuterium isotope relative abundance (dD). Students use the equation:
Temperature (deg-C)=-55.5+(dD + 440)/6 to infer temperatures from dD.
This is a complete activity that requires a working knowledge of Excel (see teaching notes and tips).
Learning Goals
- Learn about ice cores and what they can tell us about past atmospheric conditions.
- Learn about past atmospheric concentrations of CO2 and CH4.
- Learn about the climate and ice age cycle for past 160,000 years.
- Transfer text data into Excel.
- Use Excel to make and analyze graphs and to perform simple calculations.

References and Resources
- The web site Vostok data from WDC has additional background and more years of data (420,000 years) for those interested in longer records. This might be useful for follow-up discussion in lecture.
- Worldclimate Site for mean temperature and precipitation. Type in Vostok or any other city and you get back temperature and precipitation climatology.
- NASA GISS (more info) surface temperature graphs and data.
