Oceanography classes offer a wealth of knowledge on the precious and powerful ocean. From the core oceanography principles to aspects of the marine ecosystem, these classes are an exceptional way to learn more about the ocean. From the community college to a university, these classes provide access to the knowledge and field experience needed to understand the natural and economic importance that the ocean has in our lives. Oceanography classes typically involve hands-on marine research, sampling, and analysis. Course topics range from the physical and chemical oceanography to marine biology and ecology. Courses also focus on the ocean-atmosphere interaction, ocean engineering and human influences on the ocean. A typical oceanography course outlines the fundamentals of the ocean, such as its physical properties, formation and circulation, as well as basic ecological principles. Most oceanography classes involve field trips to explore the numerous types of ocean habitat, from beaches with mangroves to the open ocean. Also included in many oceanography courses is the science of GPS, Global Positioning System technology, and ocean remote sensing. Many courses will explore the practice of ocean mapping, charting and navigation, and modern satellite applications used to assess ocean conditions and help us understand the ocean environment. For students interested in gaining a greater understanding of the ocean, oceanography classes are an excellent way to gain insight and knowledge on this dynamic and powerful force. Understanding the ocean and its effects on society, is key in protecting this valuable resource.
