2500 meters. The Baffin Bay and the Hudson Strait are the largest freshwater contributors in the Labrador Current. The Hudson Strait is a narrow channel that is about 400 km long and is the opening to the Hudson Bay System, which is connected to the Labrador Sea, and contributes to 50% of the freshwater transport of the Labrador Current. The Hudson Bay is covered in ice in the winter and is ice-free in the summer. The Hudson Bay is made up of 42 rivers, contributing to the river runoff. The Labrador Current is made up of the Hudson Strait outflow, or the southeast flow, that meets with the Davis Strait and the West Greenland Current. This current then flows south, down through Newfoundland and Flemish Cap and along the continental shelf break. Part of this current moves westward along the continental slope near Nova Scotia, eventually reaching north of the Gulf Stream, this is called the Slope Water Current. The southward flow joins in the subpolar circulation, forming the narrow, western subpolar gyre in the North Atlantic. The current interacts with the Gulf Stream and the North Atlantic Current forming the western boundary current that makes up this gyre.
