Great course for the non-professional student- keeps the subject matter discussions light and contemporary. Especially loved the idea of ecological proxy, which I had never heard before!
由 KB 提供Jul 18, 2020
The professor, plus the course syllabus, and the way in which they were both presented exceeded all my hopes and expectations for learning as a beginning geology student major.
由 MK 提供Oct 5, 2020
An absolutely amazing course with an enthusiastic, engaging professor. I would give more stars if I could! I learned so much and was constantly excited for the next lesson.
