Vostok Ice Core: Excel (Mac or PC)
This material is replicated on a number of sites as part of the SERC Pedagogic Service Project
Students use Excel to graph and analyze Vostok Ice core data ( This site may be offline. ) (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).
- 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.
