The geosciences are distinct from other natural sciences. The study of the earth is interdisciplinary and historical, bringing knowledge from many other fields to help solve problems. Geoscientists investigate continents, oceans, and the atmosphere, and emphasize both the processes that have changed and are changing the earth through time and the results of those processes, such as rocks and sediments. Our fast-rising human population is dependent upon the earth for food, water, shelter and energy and mineral resources.
Study in the geosciences requires creativity and the ability to integrate. Geologists observe processes and products in the field and in the laboratory, merge diverse data, develop reasoning skills that apply through geologic time and create and interpret maps. The field goes beyond pure research science, and includes applied topics like the relationships of natural events such as earthquakes and volcanoes with human societies.
The Department of Geosciences recognizes that it is no longer sufficient just to have knowledge of the facts of the field; successful students must have quantitative skills and be able to communicate clearly through writing and speaking. Laboratory experiences are an integral part of all courses. Many courses involve the use of microscopes, including the department's scanning electron microscope. Computers are used in most courses to help students understand fundamental phenomena, obtain current information, and communicate results. Field trips are included in many courses.
Pacific Lutheran University is located at the leading edge of western North America, in the Puget Lowland, between the dramatic scenery of the Olympic Mountains and the Cascade Range. Pierce County has diverse geology, which is reflected in elevations that range from sea level to more than 14,000 feet.
Geosciences graduates who elect to work after completing a PLU degree are employed by the U.S. Geological Survey, natural resource companies, governmental agencies, and private-sector geotechnical and environmental consulting firms. Graduates who combine geosciences with education are employed in primary and secondary education.
Careers in geosciences often require post-graduate degrees. Many B.S. majors have been successful at major research graduate schools.
Faculty: Whitman, Chair; Benham, Foley, Lowes, McKenney.
The Bachelor of Science degree is intended as a pre-professional degree, for students interested in graduate school or working in geosciences. The Bachelor of Arts degree is the minimum preparation appropriate for the field and is best combined with other degree programs, such as majors in social sciences or the minor in Environmental Studies.
The department strongly recommends that all students complete MATH
140 or higher before enrolling in 300-level and higher courses in
geosciences. Students should also note that upper-division courses are
offered on a two-year cycle. Early declaration of majors or minors in
geosciences will facilitate development of individual programs and
avoid scheduling conflicts.
All courses taken for the major must be completed with a grade of C- or higher.
