Dr. Jahn's research interests are the climate of the polar regions, particularly the Arctic Ocean, with a focus on sea ice and ocean dynamics, as well as the modeling of geotracers, including miroplastics, isotopes, and idealized tracers. In the temporal space, Dr. Jahn's research spans past climates, the historical period, and future projections of climate. She is known in particular for her work on the future decline of Arctic sea ice and on the variability and change of Arctic freshwater.

ATOC 3700 - Course-Based ATOC Research Experience
Primary Instructor
-
Fall 2023 / Fall 2024
In this course-based research experience in Atmospheric and Oceanic Sciences, students will learn about how scientific research works as well as gain first research experience in Atmospheric and Oceanic Sciences by working on an authentic research project.
