How deep does the surface current known as the Gulf Stream go?

The Gulf Stream is a powerful ocean current that primarily flows at the surface and can extend to a depth of about 1,000 meters (approximately 3,280 feet). However, its most significant effects are typically felt in the upper 400 meters (about 1,300 feet) of the water column. The current can influence deeper water layers through mixing and interactions, but its main dynamics are concentrated near the surface.
