Introduction
1046px-MtBlackburn-KennicottGlacier.jpg
This lab uses a simple 1D numerical model to illustrate how a valley glacier grows and reaches equilibrium. Students can experiment by changing the Equilibrium Line Altitude, accumulation rate coefficient, valley slope, and other parameters.

Classroom organization
Lab is designed for undergraduate students majoring in earth sciences (hydrology, environmental sciences, glaciology, atmosphere and ocean sciences). The notebook is demonstration style and gives participants the possibility to explore interactively.

Learning objectives
Skills
  • basic plotting with the Python matplotlib library
Key concepts
  • equilibrium line altitude (ELA)
  • "thin ice" approximation
  • mass balance in a glacier

Lab notes
Can be used as part of a paper or problem set on glacier behavior.

This lab can be run on the CSDMS JupyterHub. (If you don't already have an account, follow the instructions to sign up at: https://csdms.colorado.edu/wiki/JupyterHub.) Run the lab Notebook by clicking the "start" link under the Run online heading at the top of this page. If you're an educator using this lab in a class, you can get CSDMS JupyterHub accounts for students. For more information, please contact us through the CSDMS Help Desk: https://github.com/csdms/help-desk.

Requirements
If run locally, this lab requires the installtion of the Python packages numpy, matplotlib, and ffmpeg.
