See Earth's #oceans in perpetual motion! 🌎🌊 NASA has created a new perpetual ocean video, which traces surface ocean currents in white and deeper ocean currents in dark blue. This clip focuses on the southern tip of Africa. Those white eddies are warm and salty rings detaching from the current after 2 years of travel. The video helps scientists understand the characteristics of these currents better and ultimately understand how heat is transported globally in the ocean. #Earth Watch the whole
