What does the term "jurisdiction" refer to in the context of the Coast Guard's duties?

The term "jurisdiction" in the context of the Coast Guard's duties refers to any area under U.S. laws and regulations. This encompasses a broad range of areas, including territorial waters, which extend 12 nautical miles from the baseline, as well as any waters within the United States and its territories. The Coast Guard has the authority to enforce laws, administer regulations, and conduct operations in these areas to ensure maritime safety, security, and environmental protection.

When considering related concepts, jurisdiction is not limited to just the high seas or federal waters, but rather includes any area where U.S. laws apply. This includes state waters and effectively means that the Coast Guard can operate under its jurisdiction wherever U.S. law is in effect. Furthermore, while the Coast Guard does have roles in international waters under specific circumstances, such as when dealing with piracy or drug trafficking, its primary jurisdiction is defined by U.S. laws and regulations, which guide its enforcement capabilities.
