  • WIM: EARTHSYS 200, EARTHSYS 191, EARTHSYS 177C, EARTHSYS 149, EARTHSYS 135, or another designated WIM course in a related department- must be approved by an advisor. Your WIM course may not also count towards your track or electives, if counted as a WIM.

(These courses must be taken for a letter grade: EARTHSYS 10, 111, 112, 210 A/B/C, WIM)


A total of seven courses are required from the Land Systems focus areas. Concentrating courses in a single focus area below will allow students to deepen their understanding of the chosen system. For breadth considerations, students are required to take a minimum of one course from each focus area. In addition, two electives are required for this track. All track courses and electives must be taken for a letter grade (nine courses total).
