NASA’S LASER SATELLITE JUST STARTED MAPPING THE SEAFLOOR - FROM SPACE
ICESat-2 was built to measure ice sheets. Instead, it’s accidentally become a bathymetry superstar.
Turns out the satellite’s laser - designed to bounce off land - can also pierce crystal-clear coastal waters and reflect off the seafloor.
Now with a new data product (ATL24), NASA and university researchers are using machine learning to map shallow ocean floors up to XXX feet deep - from orbit.
Forget sonar ships. This is seafloor scanning via satellite.
From the Bahamas to barrier reefs, what used to be “uncharted waters” just got a lot more mapped.
