The State of Maine

Maine is a state in the northeastern region of the United States. It is known for its picturesque landscape featuring rocky coastline, dense forests, and stunning mountains. The state has a rich cultural heritage, and it is famous for its seafood, particularly lobster. The state capital is Augusta, and the largest city is Portland.

Understanding State Boundaries

State boundaries are the lines that separate one state from another in the United States. These boundaries are established by law and are typically defined by natural features, such as rivers, lakes, and mountain ranges. State boundaries are important because they determine the jurisdiction of state laws, taxes, and other regulations.

The Importance of Bodies of Water

Bodies of water play a vital role in defining state boundaries. Water bodies, such as rivers, lakes, and oceans, are natural features that can be used as clear markers to establish state borders. They are also important for transportation, commerce, and recreation.

Which Body of Water Bounds Maine?

The Atlantic Ocean forms the eastern boundary of the state of Maine. The state shares its northern border with the Canadian province of Quebec, its western border with the state of New Hampshire, and its southern border with the Atlantic Ocean.

Brief Overview of the Atlantic Ocean

The Atlantic Ocean is the second-largest ocean in the world, covering approximately 20% of the Earth’s surface. It is bounded by North and South America to the west, Europe and Africa to the east, and the Arctic and Southern Oceans to the north and south, respectively.

The Characteristics of the Atlantic Ocean

The Atlantic Ocean is known for its powerful currents, including the Gulf Stream, which affects the climate of the eastern coast of North America and western Europe. The ocean is also home to a diverse array of marine life, including whales, dolphins, sharks, and fish.

How the Atlantic Ocean Became Maine’s Boundary

The Atlantic Ocean has been the eastern boundary of Maine since its statehood in 1820. Before this, Maine was part of the Massachusetts Bay Colony, and its boundaries were not well defined. The Treaty of Paris in 1783, which ended the American Revolutionary War, established the eastern boundary of the United States as the center of the St. Croix River. However, the exact location of the river’s center was disputed, leading to tensions between the United States and Great Britain. In 1842, the Webster-Ashburton Treaty resolved the dispute by establishing the current border, which follows the natural boundary of the Atlantic Ocean.

Historical Significance of the Atlantic Ocean

The Atlantic Ocean has played a significant role in Maine’s history. The state’s economy has been closely tied to the ocean since colonial times, with fishing and shipbuilding being major industries. The ocean has also been a gateway for immigration, with many Europeans arriving in Maine by ship in the 19th and early 20th centuries.

Boundary Disputes in Maine’s History

Maine’s border with Canada has been the subject of several disputes throughout its history. The Aroostook War, which took place in 1839, was a border dispute between the United States and Great Britain over the northern boundary of Maine. The dispute was eventually resolved through arbitration.

Modern-day Importance of Maine’s Boundary

Today, Maine’s boundary with the Atlantic Ocean is of significant importance for the state’s economy and tourism industry. The state’s ports and harbors are critical for the fishing industry, as well as for shipping and transportation. The state’s coastline is also a popular destination for tourists, who come to enjoy the natural beauty of the rocky coastline and pristine beaches.

Conclusion: The Atlantic Ocean and Maine’s Identity

In conclusion, the Atlantic Ocean forms the eastern boundary of the state of Maine. The ocean has played a significant role in the state’s history and identity, from its early days as a fishing and shipbuilding center to its modern-day economy and tourism industry. As Maine continues to evolve, its relationship with the Atlantic Ocean remains a critical part of its cultural heritage and economic future.
