Collaborative Research: Combined Physical Property Measurements at Siple Dome - Spencer_0917509

This award supports a two-year collaborative effort to more fully understand the climatic history and physical properties of the Siple Dome, Antarctica deep ice core. We have released an Excel file with firn depth-density data from 88 sites, with site location and name included in the accompanying pdf file. Also made available is a comma-separated csv file for bubble-number densities in glacier ice, in units of bubbles per cubic centimeter, based on firn densification and grain-growth modeling under steady-state climate conditions. The leftmost column is accumulation rate in centimeters water equivalent, and the top row is temperature in Kelvin.
