[Geoldept] UW summer internship

[Melissa Rice]

Geology undergrads: see below for a super cool (pun intended) internship opportunity this summer!


---
Are you an undergraduate interested in doing paid research on snow and ice this summer? If so, please apply to the University of Washington Cooperative Institute for Climate, Ocean, and Ecosystem Studies Research Experience for Undergraduates program before 1/31/25! For eligibility and details on the application process, please refer to: https://cicoes.uw.edu/education/internships/<https://urldefense.com/v3/__https://cicoes.uw.edu/education/internships/__;!!IKRxdwAv5BmarQ!a4F-dtMz2QQM7DrH65b__SZ3zLOGackguEpwXANz0GAcJT9QpeLqxowfVIYKVupr1Qo1tWBe6tuBB3syDn0SwQ$>


Effects of surface roughness and impurities on ice thickness and photosynthesis during Snowball Earth
Mentor: Dr. Aditya Khuller, UW Polar Science Center, UW Applied Physics Laboratory

About 700 million years ago, the Earth is thought to have been covered almost entirely with glaciers. During this “Snowball Earth” period, some areas without highly reflective snow overlying bare ice would have existed if conditions favored the evaporation (sublimation) of snow at the surface. If the exposed, underlying ice was thin and clear, photosynthesis could have continued beneath this bare ice. We will use an existing, validated set of models to calculate the penetration of sunlight into ice and calculate the atmospheric energy transfer into different ice surfaces on Snowball Earth. Together, we will explore the effects of: 1) the roughness of the ice, which affects evaporation rates; and 2) the presence of impurities, such as dust in the ice, which affects the amount of sunlight that can be transmitted for photosynthesis to occur.

Skills and requirements:

  *   Experience with coding is preferred; otherwise, a willingness to learn basic coding in MATLAB
  *   Interest in climate science and interdisciplinary research
