Satellites track Antarctica's climate-regulating underwater waterfalls

Scientists can now track climate-regulating underwater waterfalls in Antarctica using satellites, a breakthrough that could help monitor climate change. This new method measures subtle dips in sea level to observe the deep ocean currents. The discovery allows for monitoring of the deep ocean currents, which are slowing down due to Antarctic ice melt and warming waters. These currents, crucial for global climate regulation, transport heat, carbon, and nutrients. Previously, tracking these underwater waterfalls was difficult and expensive. The new satellite method offers a cost-effective, carbon-neutral way to monitor these critical currents and their impact on the climate.
