斯克里普斯海洋学研究所提供的本科专业是海洋生物学，并获得了学士学位。该专业的本科生将对海洋生物的生物学以及影响这些生物，其种群以及沿海和海洋生态系统的生物和物理过程有所了解。该专业需要自然科学的基础，海洋生物学课程的严格核心以及统一的实验室/野外课程，以使学生更直接地参与发现过程以及数据的分析和解释。专业人士从越来越多的海洋生物学和相关学科的高级斯克里普斯海洋学课程中选择选修课。海洋生物学课程充分利用了加州大学圣地亚哥分校在太平洋沿岸的独特地理位置。实验室工作和潮间带，盐沼和其他海洋生态系统的实地考察是该
The Scripps Institution of Oceanography offers an undergraduate major program in marine biology, resulting in a BS. Undergraduates in this major will develop an understanding of the biology of marine organisms and the biological and physical processes that affect these organisms, their populations, and their coastal and oceanic ecosystems. The major requires a foundation in the natural sciences, a rigorous core of marine biology courses and a unifying laboratory/field course that engages students more directly in the discovery process and in analyzing and interpreting data. Majors select electives from a growing set of upper-division Scripps Oceanography courses in marine biology and related disciplines. The marine biology curriculum takes advantage of the UC San Diego's unique physical location along the Pacific Ocean. Laboratory work and field trips to intertidal zones, salt marshes, and other marine ecosystems are important components of the instructional program. Ocean sciences are relevant to many contemporary environmental issues and problems and central to understanding earth-system evolution, dynamics, climate and sustainability. A major in marine biology is an appropriate start for students who are seeking a career or graduate studies in marine biology and related biological disciplines, a career in fields such as marine conservation, or simply interested in the major to broaden their base of knowledge and experience in the biological sciences. Program advisers and faculty can provide additional information on career and graduate school opportunities. It is strongly recommended that all marine biology majors meet regularly with academic advising staff in the Scripps Institution of Oceanography Undergraduate Education Office in Galbraith Hall and with the marine biology faculty adviser to discuss and update curriculum choices.
