interoceanic

Interoceanic refers to something that connects or relates to two or more oceans. This term is most commonly associated with transportation routes, particularly canals, that allow ships to travel between oceans without circumnavigating continents. The most prominent example is the Panama Canal, which connects the Atlantic and Pacific Oceans, dramatically shortening shipping routes and influencing global trade.

Historically, various projects have been conceived or undertaken to create interoceanic passages. These have ranged from proposals for canals across continents to the development of transcontinental railways that served a similar purpose by facilitating the movement of goods between ocean ports. The strategic and economic importance of such routes has made them focal points for international relations and infrastructure development.

Beyond artificial waterways, the concept of interoceanic can also apply to natural geographical features or phenomena that link major bodies of water. For instance, certain straits or passages might be considered interoceanic if they provide a vital connection between large oceanic systems. The term emphasizes the linking of distinct, vast marine environments.
