Marine Biology and Coastal Sciences represents the wide variety of ecosystems that are linked through water. Study in this field encompasses freshwater lakes and streams, estuaries and coastal marine habitats that are critical for numerous plants and animals, but can be compromised by human activities. Students who pursue this major are interested in understanding the relationships among plants, animals and humans while learning how to protect and restore these necessary ecosystems. The interdisciplinary Marine Biology and Coastal Sciences programs emphasize the four core sciences: biology, geology, chemistry and physics. Along with the Marine Biology and Coastal Sciences (MS) degree, the department also offers a combined BS/MS in Marine Biology and Coastal Sciences.
