理学学士学位（BSc）是三年制本科学位，使每个学生都可以发展自己在理科（理科专业）和相关科目的兴趣。学生可以灵活地将其主要学科与其他科学学科以及全校其他学科的学科相结合。在这个星球上，没有什么比海洋更能将地方，国家和全球问题联系在一起了。奥塔哥的海洋学包括海洋物理学，化学和地质学的研究。它从第一年的大规模全球性系统（如第一年的海洋环流）发展到局部的局部性问题（如第三年的奥塔哥港口疏such）。
This watery world is so challenging to explore, that we have more detailed maps for the surfaces of the Moon, Mars, and Venus. Yet understanding our ocean planet is essential for meeting the challenges of our collective future. The physical, biological, chemical, and geological processes that power the Earth system unite in the ocean, determining Earth's climate, regulating the composition of our atmosphere, supporting human civilisation, and sparking our curiosity. Otago is uniquely placed to study these interlinked processes and their effects on our lives. The Southern Ocean is on our doorstep, with a wide range of marine environments easily accessible to our research fleet. We work from shallow harbours to the deep ocean, around sub-Antarctic islands and in majestic fiords, alongside temperate coastlines and floating over tropical reefs.
