It is generally considered a warm current, transporting warmer, saline water from the western Atlantic eastwards.
It originates from the southward turn of the Brazil Current around 40°S and flows eastward across the Atlantic until it approaches the African coast, where part turns north to feed the Benguela Current and part joins the Antarctic Circumpolar Current.
It is a crucial component of global heat distribution, affects marine ecosystems, influences regional weather and climate (e.g., rainfall in coastal Africa), and is part of the larger global 'conveyor belt' that regulates Earth's climate.
Not directly from the surface. Its path and characteristics are mapped using satellite data (sea surface height/temperature), drift buoys, and scientific measurements of water temperature, salinity, and flow velocity at depth.
