The Northwest Atlantic refers to the part of the Atlantic Ocean located off the northeastern coast of North America. This region includes important bodies of water such as the Gulf of Maine and the Bering Sea, and is known for its rich marine biodiversity. It is home to various species of fish, marine mammals, and seabirds, making it a vital area for fishing and ecological research. The Northwest Atlantic is also significant for its economic activities, particularly commercial fishing and shipping. Major cities like Halifax and Boston are located along its shores, contributing to trade and tourism. Environmental concerns, such as overfishing and climate change, are critical issues affecting this region.
