Taiwan's acidic underwater hot springs

...""The underwater landscape looks like it's from another world," explained Dr Mario Lebrato, who made dozens of dives here as part of a 10-year time series study (2009 to 2018) led by the Institute of Geosciences at the University of Kiel in Germany in collaboration with Taiwanese and Chinese researchers.
