Environmental Earth & Ocean Sciences (EEOS)

The Bachelor of Science (BS) in EEOS is a 4-year course of study focusing on the physical science basis of humans’ interaction with the earth system. The BS EEOS major provides education and research training in environmental earth sciences with specific focus on the geological and ocean realms. The program offers three tracks, one in Environmental Geology, the second in Environmental Ocean Sciences, and the third in Environmental Earth Sciences. Every BS EEOS student takes common blocks of courses focusing on fundamental environmental Earth sciences, investigative methods, and field techniques. The program offers a high degree of flexibility to allow students to choose courses and curricula that best fit their science interests and career goals.  Students may choose courses to prepare them to enter the geoscience workforce immediately upon graduation or select courses designed to prepare them for graduate work.

New Programs Promote Excellence in Environmental Earth and Ocean Sciences

Millersville University's EEOS degree engages students in hands-on field and laboratory-intensive activities that train them to solve today’s complex environmental problems.

"Today, more than ever, environmental problems require transdisciplinary approaches to affect complex and dynamic solutions. This new EEOS program provides students with the breadth and depth that they will need to become the workforce of tomorrow. At its core, the curriculum is steeped in experiences that are authentic and contemporary, where students learn skills that they will value throughout their careers and allow them to contribute in ways that are relevant and meaningful," says Dr. Richard Clark, Earth Sciences Department Chair.

EEOS students will gain technical expertise in investigative methods and practical experience in communicating environmental science to both novice and professional audiences. Graduates of the environmental geology concentration meet the necessary curricular requirements to be eligible for professional licensure, and graduates of the BS EEOS program will be able to immediately step into a variety of careers including:

  • Environmental Scientist
  • Environmental Monitoring Specialist
  • Geologist/Field Geologist
  • Oceanographer
  • Watershed Manager
  • Hydrologist/Hydrogeologist
  • Hydrographer
  • Remote Sensing/Geodetic Surveying Specialist
  • Coastal Geologist
  • Marine Policy Specialist
  • Government Research Scientist
  • Coastal Resources Analyst
  • Environmental Educator

The new inclusive degree will be accessible to students from a variety of backgrounds and provide flexibility in course requirements so that students may explore their environmental interests.
