Majoring in Marine Science

If you want to understand life on Earth, you have to understand the ocean. Not only are most living creatures actually in the ocean that covers two-thirds of the planet, but many of Earth’s major processes are also connected to its physical properties. Studying marine science at UD, you will learn marine biology, oceanography, geology, and other related sciences, as well as policy and environmental management.
