Gulf Stream
The Gulf Stream is a strong, warm ocean current in the North Atlantic that flows northward along the eastern coast of the United States and Canada before turning toward Europe.
The Gulf Stream is a strong, warm ocean current in the North Atlantic that flows northward along the eastern coast of the United States and Canada before turning toward Europe. It is part of the North Atlantic subtropical gyre and helps moderate climate on both sides of the Atlantic. As one of the fastest currents in the world ocean, it is narrow, deep, and fast due to western intensification.
Geography and path
The Gulf Stream begins in the Straits of Florida and flows northward along the eastern coast of the United States, extending toward eastern Canada before turning northeast across the Atlantic. It becomes part of the broader North Atlantic current system.
Formation and dynamics
The current is associated with the North Atlantic gyre and is driven by wind stress, the Coriolis effect, and large-scale ocean circulation. As a western boundary current, it is intensified, which makes it unusually narrow and swift.
Climate and ecological effects
By transporting heat northward, the Gulf Stream helps moderate temperatures in the North Atlantic region, including parts of western Europe. It also affects marine life distribution, weather patterns, and potentially hurricane behavior and sea level along parts of the Atlantic coast.
Historical observation and research
Benjamin Franklin is commonly credited with early mapping of the Gulf Stream in the 18th century. Modern research has also examined changes in its strength and position, including reports of weakening in recent decades.
Key facts
- The Gulf Stream is a major warm western boundary current in the North Atlantic.
- It carries warm tropical water northward from the Florida Straits along the U.S. East Coast.
- It is one of the fastest currents in the world ocean.
- It influences climate, weather, and marine ecosystems across the North Atlantic.
- Historical accounts credit Benjamin Franklin with first mapping the current in the 18th century.
The Gulf Stream passes along the Atlantic coast of Canada and influences the climate and marine conditions of Atlantic Canada, including by helping transport warm water northward in the North Atlantic system.[1][3][10]
